BOATING — The Washington Department of Fish and Wildlife public access site at Newman Lake will be closed June 3-5 to allow treatment of the lake with herbicide to control Eurasian milfoil and other aquatic invasive weeds.
The Newman Lake Flood Control Zone District, under permit from the Washington Department of Ecology, has hired Aqua Technex to treat milfoil infestations on about 80 acres throughout the 1,200-acre lake with 2-4-D (dichlorophenoxyacetic acid, dimethylamine salt).
A swimming restriction will be in force during treatment and for 24 hours after treatment. Boating and swimming will be discouraged the day of treatment and for two days after. Signs with that information will be posted. The boating restriction is needed because wave action reduces the herbicide’s effectiveness.
Karen Kruger, Spokane County Water Resources Technician, says last summer’s aquatic weed treatment at Newman Lake went well, thanks in part to volunteer efforts to help keep boaters out of the herbicide application area.
Aquatic herbicide application permits authorized by Ecology include requirements and restrictions to protect fish and wildlife.
WDFW lands manager Brian Trickel said the gates to the area will be closed early on Tuesday, June 3, and re-opened early on Friday, June 6.
Newman Lake is about 20 miles northeast of Spokane, about two miles west of the Idaho border, and is open year-round for fishing.
WILDLIFE WATCHING — The Eurasian collared-dove is an exotic species that's unprotected in Washington and Idaho and can be shot by licensed hunters year-round where hunting/shooting is allowed. They're delicious, too.
- See today's outdoors column on this imported and not necessarily welcome species.
- See an eBird chart that graphically shows the spread of ECD sightings across North America in two-year intervals.
But it's important to be able to distinguish the collared-dove from the similar mourning dove, which can be hunted only during designated September seasons.
Eurasian collared-doves are larger than mourning doves and slightly lighter in color. Aside from the diagnostic black collar on the backs of their necks, they also have a squared tail as opposed to the pointed tails on mourning doves.

BOATING — Mandatory watercraft inspection stations have barely opened for the season in Idaho, and they already have reported finding the year's first boat fouled with quagga mussels, a potentially devastating invasive species.
The boat was checked at the Cotterell Port of Entry station on Interstate 84 near Burley.
The program aims to inspect boats that are entering the region from mussel-infested states. The boat intercepted at the Cotterell inspection station recently spent time in Lake Powell in the Glen Canyon National Recreation Area. Lake Powell, operated by the National Park Service, recently was identified as infested with quagga and zebra mussels.
The National Park Service still does not require decontamination of watercraft leaving its facilities with mussel infestations, even though it means possible introduction of these invasive species to the clean waters of the Pacific Northwest. This also indicates that potentially infested boats are being transported outside of the traditional boating season, which is a concern for Pacific Northwest states.
Since Idaho initiated its watercraft inspection program in 2009, nearly 200,000 boats have been inspected. About 100 mussel-fouled boats have been intercepted and decontaminated before they launched into Pacific Northwest waters, the Idaho Department of Agriculture reports.
“Idaho’s watercraft inspection program underscores the importance of preventing these mussels from becoming established in Idaho’s waters,” Agriculture Director Celia Gould said. “All of Idaho’s waterbodies have tested negative for these species, but they have been found in waters of other western states, and are causing severe economic and environmental harm in other regions of the country. We continue to work with our regional partners to prevent these fouled boats from launching in Pacific Northwest waters.
“Catching mussel-fouled boats so early in the season is a real wake up call. The more the public is educated about these invaders, the more enthusiastic and vigilant they are in joining efforts to keep them out of the Pacific Northwest.”
Idaho law requires all boaters must stop at the stations, such as the one on Interstate 90 near Fourth of July Pass.
Watercraft inspectors are looking for high-risk boats that have been in quagga- and zebra-mussel impacted waters such as Lake Powell, Lake Mead, Lake Havasu and Lake Pleasant.
If you have launched in a mussel-infested waterbody in the last 30 days, you must have an inspection before you launch in Idaho. For a complete list of infested waters, a five-year summary of inspection efforts, and a list of Idaho inspection stations, see: www.invasivespecies.idaho.gov

INVASIVE SPECIES — Having the invasive quagga mussels booming in Utah's Lake Powell is like having a deadly contagious disease at a major national airport with folks coming and going in all directions — including Idaho, a federal biologist says.
He's trying to get the word out before boaters flood out of Idaho to Utah for spring break.
Here's the story from Rob Thornberry of the Idaho Falls Post Register:
With Utah finding more quagga mussels in Lake Powell, the likelihood they will find their way to Idaho is increasing, said Lee Mabey, a forest fisheries biologist with the Caribou-Targhee National Forest.
Having the mussels in Lake Powell is like having a deadly contagious disease at a major national airport with folks coming and going in all directions, including Idaho, Mabey said. The rate of spread of the mussels could be very rapid now that Lake Powell is infected.
Mabey is trying to raise awareness of the problem before people travel south for spring break.
Data from the Idaho Department of Agriculture’s five years of boat inspections indicates Lake Powell is the most frequently visited mussel-fouled water body by Idaho boaters. Many of these vessels have been out of the water less than 30 days at the time they are inspected, posing a significant risk of transporting larval or adult mussels to the Gem State.
In 2013, Idaho inspected 568 boats that had recently come from Mead, Powell, Mohave, Havasu or Pleasant lakes. All those waters have mussels.
Idaho does not, and officials are keen on keeping it that way.
If quagga or zebra mussels take hold in Idaho, the state’s lake fisheries will be forever changed and the irrigation and hydropower industry could face millions of dollars in added expenses. Undoubtedly these expenses will be passed on to the consumer, Mabey said.
Quagga mussels are prolific breeders and attach themselves to hard and soft surfaces. Once in a lake, they filter plankton from the water, robbing fish of food.
“If we get these mussels in our lakes, it is going to turn the ecology upside down,” Mabey said. “Our fish populations would crash. It is simple biology — a lake only supports so much biomass. You can have plankton and fish or you can have plankton and mussels.”
Mabey encourages all anglers and boaters to take the threat seriously and learn about proper precautions to keep the marauders out of Idaho.

“We need everybody to take part in prevention,” he said. “We can’t rely on just inspection stations. We need to have a change in mentality of all users. Just like anglers have adopted catch-and-release regulation, we need boaters and all water users to adopt clean, drain and dry after each excursion.”
Jordan Nielson, a Madison High School graduate, is the aquatic invasive species coordinator for the Utah Division of Wildlife Resources. He said government agencies are doing well to slow the spread of mussels, but those efforts will be wasted if boaters don’t change their habits.
“We need a paradigm shift,” he said. “The state agency can only do so much. People have to realize they have a responsibility when they go boating to make sure they aren’t moving things around. It is essential.”
At the recent Western Governors Association meeting in Las Vegas, Idaho Gov. Butch Otter brandished a license plate that had been soaked for a year in Lake Mead and was encrusted with invasive quagga mussels, asking Interior Secretary Sally Jewell when the Obama Administration would get inspection and contamination stations up and running at the infested lake to help halt the spread of the invasive species. BSU political science professor Justin Vaughn was in the audience, and reported that Jewell made it clear she’s aware of the issue and said she’d look into it; his full report in the Blue Review is online here. Vaughn reported that Otter offered Jewell the mussel-encrusted license plate to take back to Washington, D.C., but she declined – it’s illegal to transport invasive species.
Idaho Rep. Eric Anderson, R-Priest Lake, soaked 500 of the license plates in the infested lake for displays to help make the point about the threat from the mussels, which haven't yet invaded Idaho. “We'll lose so much if these get into our region,” he said, adding that he was “thrilled” to see the issue take center stage so dramatically at the WGA conference.
INVASIVE SPECIES — An Independent Economic Advisory Board update released last week indicates that the money spent – an estimated $5 million per year from a variety of sources — in attempts to ward off an invasion of non-native zebra and quagga mussels into the Columbia River basin is money well spent.
However, the report acknowledges there's still a probability the damaging species will eventually get into the Columbia and Snake River systems and raise havoc for irrigators, municipalities and hydropower managers, not to mention boaters and anglers.
See the story from the Columbia Basin Bulletin.
FISHING — This story took me back to the Pend Oreille River about 10 years ago…
Northern pike have made their way into the Upper Colorado River
Utah has already put a $20 bounty on northern pike, the toothy adversary of a healthy trout population, and with a confirmed catch of the invasive predator—and, unfortunately, its live release into the Colorado River at Pumphouse Recreation Area, Colorado should consider a similar program to rid the waters of pike—which have no place in the Colorado River.
A column by Scott Willoughby, Denver Post; Aug. 7
STATE PARKS — A group of volunteers from various local groups — more are needed! — are meeting Wednesday in an effort to curb the spread of knapweed in Mount Spokane State Park.
To join the group, wear good boots and meet at 10 a.m. at the hairpin turn parking lot inside the park at the Mount Kit Carson Loop Road trailhead.
- RSVP to firstname.lastname@example.org
- Info: Jeanie, (509) 467-8149.
Bags will be provided but bring gloves and whatever else you need to be comfortable working outdoors in the sun (water, hat, sun glasses, snacks/lunch, sun screen etc). A small spade or old screwdriver might also help.
The group plans to work for a couple hours, break for lunch and then perhaps hike the park trails in the afternoon.

ENVIRONMENT — Anglers wading in rock snot or hikers walking through fields of spotted knapweed should be easy converts to the U.S. Department of Agriculture's new campaign to raising awareness of invasive species.
Native plant and wildlife species suffer the most from invasions of exotics.
If everyone chips in, the costly battle against a long list of invasives could be more effective.
USDA's Animal and Plant Health Inspection Service has summarized the campaign in “Seven Simple Steps” to leave invasive pests – non-native insects, other animals, plants and diseases that feed on America’s crops, trees and plants – behind.
The national “watch list” has been expanded to include 15 of the most damaging “Hungry Pests” that can cause havoc with our native flora and fauna.
A new invasive insect has turned up in Ada and Kootenai counties, prompting warnings from the state Department of Agriculture. The Japanese beetle, a half-inch-long, shiny metallic-green bug with copper-brown wing covers, destroys trees, rose bushes, stone fruits, garden and field crops, and its larvae or grubs destroy turf by feeding on the roots of grass. If you seen green and yellow traps, that's what they're for; Ag is also asking anyone who finds one of the bugs to place the dead specimen in a baggie and mail it in - there's more info here. The beetle first was introduced to the United States in plants imported from Japan.
Idaho, Oregon and Washington have jointly launched a “Squeal on Pigs” campaign to combat the latest invasive species - feral swine - that's turned up in all three states. Originating in Europe and Asia and imported for domestic use, the wild pigs, also known as the Russian boar, can grow to several hundred pounds and cause extensive damage to crops, wildlife and habitat; the three states' invasive species councils want folks to be on the lookout for the swine in the wild and report them if seen.
It's not just their destructive rooting and grubbing. Feral swine, defined as any pig that is not confined within a fenced property, often carry diseases that may be transmitted to livestock or humans; they prey on lambs, calves, fawns, upland birds and other wildlife; and they're remarkably fertile, producing a couple of litters of four to eight piglets a year and traveling long distances to invade new watersheds. Oregon has the most of the three states right now - 3,000 to 5,000 - and the Northwest states don't want to end up like heavily infested Texas, which sees more than $50 million a year in damage from feral swine.
“We don't know who brought 'em in or how they came,” said Amy Ferriter, Idaho's invasive species council coordinator. “That's really why we're trying to get the word out. If people see these things in the wild, they should report them to us.” The “Squeal on Pigs” campaign includes a toll-free hotline number to call: (888) 268-9219. The campaign's full slogan is: “Squeal on Pigs! Protect our Water and Land from Feral Pigs.” You can read my full story here at spokesman.com.
INVASIVE SPECIES — A dive team to assess an outbreak of invasive asian clams in the Hope area of Lake Pend Oreille is being organized for Monday by the Idaho Department of Agriculture and Bonner County.
The clams were detected recently during the pre-runoff lake drawdown.
- Meanwhile, Idaho boat inspection stations already have intercepted 11 boats bringing invasive species into the state.
This is serious business. Somebody let down their guard and brought these clams into the lake, probably by not cleaning their boat after using it outside the area.
The clams multiply fast, suck in algae and excrete high-nutrient pellets that can foul water and turn those famous clear-water bays green.
Apparently we need to crank up the penalties to thousands of dollars and JAIL TIME to get the message out.
Idaho Department of Agriculture’s boat inspection stations, open since March 1, already have caught 11 boats entering Idaho carrying invasive mussels into Idaho.
The department has set up 15 inspection stations across the state as a line of defense against the invasion of zebra or quagga mussels.
If you think it's an inconvenience, you're not educated on the subject.
INVASIVE SPECIES — Washington, Idaho and Oregon are among the Northwest states and provinces involved in lobbying the federal government to assure that a $1 million appropriation line item in the Department of Interior’s 2012 budget is spent to help cut off the spread of invasive quagga mussels from a main source – the Lake Mead National Recreation Area.
Other states and groups involved in the campaign include the Northwest Power and Conservation Council, Colorado River Fish and Wildlife Council and Pacific Northwest Economic Region, according to a Columbia Basin Bulletin report.
Last year several boats infested with invasive species from Lake Mead were intercepted by Northwest states at highway check stations. The Northwest region’s water-related infrastructure such as hydro projects and irrigation systems is at risk, as well as recreation and aquatic environments.
Tens of thousands of boat inspections later, Idaho and Washington have come through another boating season without getting invasive quagga or zebra mussels established in either state's waters - but there were plenty of close calls. Idaho intercepted 24 mussel-contaminated boats entering the state, and Washington decontaminated 20. While most were coming from the heavily infested Great Lakes region, nearly half were Northwest-bound from federal waters in Arizona and Nevada - and that has officials in both states concerned.
“Mussel-fouled boats continue to leave infested waters without proper decontamination,” Idaho Department of Agriculture Celia Gould said. “The federal government needs to do a better job of containing infestations in their waters and preventing the spread of these species to the Pacific Northwest states.”
Allen Pleus, aquatic invasive species coordinator for the Washington Department of Fish and Wildlife, said the good news is this: “To our knowledge, there are no established or known detections of zebra or quagga mussels in any Columbia River Basin locations, including British Columbia, Montana, Idaho, Oregon and Washington. So we're the last great water basin without these species in the United States.” You can read my full story here from Sunday's Spokesman-Review.
BOATING — Idaho’s $7 invasive species sticker, which is required on all boats and inflatables longer than 10 feet, cannot be transferred from one vessel to another, Idaho Parks and Recreation officials say.
A story in the Sunday Outdoors section (Aug. 7) suggested otherwise, noting that some boaters were laminating the stickers for more practical attachment such as a cord or zip tie, especially in the case of their rafts.
“Vendors that offer convenient solutions to affixing them to inflatable rafts with rope rigging are doing just that – providing a convenient solution to affixing them to a designated vessel,” said Jennifer Blazek, department spokeswoman in Boise.
But she advised, “The rules are still the rules. The sticker is non-transferrable.” Here's the Idaho Code to prove it.
She acknowledged that nothing on the sticker says it can’t be transferred, but said it’s stated in the rules.
Beyond that, she said the fee is for a good cause dear to the hearts of all boaters.
“Contributions to the Idaho Invasive Species Fund are put to service protecting our coveted waters from invasive species that can devastate a recreational hotspot in a year or less,” she said. “It’s an important program that should be taken seriously.”
EXOTIC SPECIES — Care for a nutria burger? Or maybe a dab of didymo “rock snot” on your ice cream?
With a boost from creative marketing, the bloated American appetite could help control exotics while conserving imperiled native species.
An invasive species called lionfish is devastating reef fish populations along the Florida coast and into the Caribbean. According to a New York TImes report, an increasing number of environmentalists, consumer groups and scientists are seriously testing a novel solution to control it and other aquatic invasive species — one that would also takes pressure off depleted ocean fish stocks: they want Americans to step up to their plates and start eating invasive critters in large numbers.
The United States Fish and Wildlife Service is now exploring models suggesting that commercial harvest of Asian carp in the Mississippi would most likely help control populations there, “as part of an integrated pest management program,” spokeswoman Valerie Fellows told The Times.
When they find tastey recipes for spotted knapweed, cheatgrass, rush skeletonweed, milfoil and zebra mussels, we'll be on the road to recovery.
BOATING — Aquatic Invasive Species (AIS) check stations will be set up this weekend in several locations in Eastern Washington, the state Fish and Wildlife Department announced this afternoon.
These are mandatory stops for anyone on the road with watercraft of any kind.
Officers will be looking for zebra and Quagga mussels and other plant and animal invasive species that can be extremely hazardous, both to native fish and wildlife and to water systems, if introduced to Washington waters.
The Check Stations will run from 8 a.m. through at least 3 p.m., and will be highly visible with signs, as follows:
- Saturday, on Highway 2 just north of Spokane (near Chattaroy transfer station).
- Saturday, on Lake Roosevelt, at National Park Service boat launch sites, including Kettle Falls.
- Sunday, on Snake River boat launch sites, including Clarkston.
For more info on AIS, see the Fish and Wildlife Department's webpage at http://wdfw.wa.gov/ais/.
BOATING — North Idaho has five invasive species boat inspection sites open through Sept. 9 to check boats for zebra and Quagga mussels that could infest the state's waters.
The state Agriculture Department's Invasive Species Program is operating the sites 7 a.m.-7 p.m. as follows:
- Cedars, on westbound Interstate 90 at Fourth of July Pass.
- Huetter Rest Stop, on westbound I-90 between Post Falls and Coeur d’Alene.
- Garwood, moved this year to Highway 53 (Trent) near the state line.
- Old Town on Highway 2 east of Newport.
- Samuels on Highway 95 north of Sandpoint.
People transporting a watercraft near boat inspection stations are required to stop.
When going to any different water, remember to Clean, Drain, and Dry your boat.

INVASIVE SPECIES — Mike Wilkinson, the Washington Fish and Wildlife Department’s aquatic invasive species biologist, will give a free program focusing on the threat of zebra mussels invading the region’s waters on Tuesday, 7 p.m., at the Inland Northwest Wildlife Council office, 6116 N. Market St.
INVASIVE SPECIES — Washington officials found invasive zebra mussels on a boat coming into Washington Saturday at the stateline port of entry near the Idaho border.
Both Idaho and Washington are ramping up their surveillance for these invasives with horrible consequences to our waterways.
Read on for more about this particular case as well as about Idaho's mandatory boat check stations.
INVASIVE SPECIES — Washington state is keeping a close eye on the feral pig populations in Oregon, where the fish and wildlife department has ordered farmers to determine the size of the destructive pig populations on their land and get rid of them.
An Oregon Department of Fish and Wildlife official says the feral pig populations are likely moving north from groups in California, where they are hunted as game.
The Capital Press reports a group of between 50 and 100 feral pigs in southwestern Idaho was culled to 20 through surveillance and tracking in the area, and Oregon hopes to duplicate that success.
States in the Midwest and Southeast suffer from massive feral pig populations that wreak havoc on valuable crop land.
Oregon officials hope to eradicate them before that happens.
WATERWAYS — Two boats infested with invasive mussels were intercepted at a North Idaho checkpoint, state officials said Monday.
Idaho Department of Agriculture said in a press release the boats were stopped at a station on Interstate 90 near Wallace on Thursday. The Coeur d’Alene Press reports one of the boats was headed to Lake Coeur d’Alene in Idaho, while the other was destined for Gig Harbor in western Washington.
The mussels have many western states taking preventative steps because they can destroy food chains, threaten waterways and fisheries. So far, Idaho waters are free of the invasive species, but two years ago the state Legislature passed laws requiring that all boats be tested.
Post Falls Mayor Clay Larkin says last week’s incident underscores the threat that invasive mussels pose to Idaho.
INVASIVE SPECIES — You've probably heard about the dangerous investations of “flying” silver carp in the Midwest. Trust me: we don't want them.
Check out this video and consider whether it would be any fun to take a kid fishing and boating in Indiana's Wabash River.
INVASIVE SPECIES – Sandpoint-area residents are organizing this week to pounce on an new unwanted aquatic invader to Lake Pend Oreille.
A public work party to stop the spread of flowering rush will begin Saturday, 1 p.m., at Sandpoint City Beach.
Like other aquatic invasive plants, flowering rush crowds out native vegetation and interferes with swimming and navigation. Yet, in some places, it's sold as a decorative plant.
According to the Bonner County Aquatic Invasive Species Task Force, the infestation is still at a manageable level, but the group is devoting the week to coordinating with school groups to tackle flowering rush infestations in Boyer slough, Denton Slough, Clark Fork Delta and Dover.
Read on for details.
BOATING — Mandatory watercraft inspection stations targeting invasive species have opened at three sites in the Idaho Panhandle, with two more to open in May.
And don't forget Idaho's invasive species sticker requirement for most vessles. The sticker comes with Idaho boat registrations, but a separate sticker must be purchased if your boat is registered out of state or if you have an unregistered non-motorized craft. All non-motorized boats over 10 feet long, including inflatables, are required to have a sticker.
Idaho's boat inspection sites will check vessels for standing water and signs of quagga and zebra mussels. Inspectors will ask boaters where their craft has been in the previous 30 days. All boats should be clean, drained and dry when they arrive in Idaho.
Inspection stations the state Agriculture Department has opened so far are:
- Cedars, on westbound Interstate 90 at Fourth of July Pass.
- Huetter Rest Stop, on westbound I-90 between Post Falls and Coeur d’Alene, operating Friday, Saturday and Sunday until May 15 when it will begin opening daily.
Garwood, moved this year to Highway 53 (Trent) near the state line, open on same schedule as Huetter station.
These stations will be open 7 a.m.-7 p.m. through Sept. 9.
Stations at Old Town on Highway 2 east of Newport and Samuels on Highway 95 north of Sandpoint, are set to open on May 15.
The inspections are an effort to keep invasive mussels out of Idaho’s waters.
Zebra and quagga mussels are prolific breeders, attaching themselves to hard surfaces where they clog intake pipes and foul freshwater ecosystems. The mussels have infested the Great Lakes. In recent years, they’ve been found in parts of Nevada, Utah, California, Arizona and Colorado.
INVASIVE SPECIES — Eloika Lake's “milfoil monster” will be addressed in an upcoming program geared to anglers, property owners and anyone else who wants information on this threat to a popular lake — and the waters downstream.
Local Wildlife” photos and the “Eloika Milfoil Monster” are two visual presentations scheduled by the Eloika Lake Association on Thursday, March 31, 6:30 p.m. at the Inland Grange in Elk. Folks who sign in will be entered in a free drawing for an air boat tour of Eloika Lake courtesy of Lake Restoration Services.
Jim Bottoroff, Department of Natural Resources wildlife biologist, and David Ross, Spokane Conservation District resource technician, will present photos and stories and answer audience questions about wildlife and wild aquatic weeds commonly found near Eloika starting at 6:30 p.m. at Inland Grange.
The grange is located at 37147 N. Conklin Rd., southeast of Elk at the corner of Conklin and Nelson roads.
Even though fishing on Eloika Lake remains good, a project is underway to address the threat invasive Eurasian Water Milfoil plant poses to fisheries. This summer marks the second year that milfoil will be treated as part of a state grant acquired by the Eloika Lake Association in cooperation with the Spokane County conservation district.
“Last year there was a 95percent success rate in the areas treated for Milfoil, so this is really good news for anyone who recreates here,” said Tammy Magnuson, Vice President of the Eloika Lake Association.
WILDLIFE — An exotic furry critter resembling a cross between a beaver and a muskrat is gaining ground in the Pacific Northwest, and that's not something to get all warm and fuzzy about.
The U.S. Fish and Wildlife Service released videos this week about thegrowing presence of non-native nutria in Oregon and Washington, two of 15 states with stable or increasing nutria populations.
The invasive mammals, native to South America, cause ecological damage and are potentially harmful to native wildlife, native plants and potentially to humans.
Nutria prosper in urban and suburban areas. Louisiana and Maryland are considered beyond eradication, a fate that could come true in the Pacific Northwest. Under the right conditions, biologists say, a breeding pair of nutria can lead to 16,000 offspring in three years.
“Nutria are symbolic of many aquatic invasive species, in that they're often out-of-sight, out-of-mind and even frequently mistaken as native wildlife,” said Paul Heimowitz, the Service’s Pacific Region Aquatic Invasive Species Coordinator.
The rodents over-graze wetland habitats, compete with native species, and can cause erosion by tunneling
into stream banks. In the future, climate change could increase nutria populations, whose range is currently limited by cold winter temperatures.
INVASIVE SPECIES – Idaho’s Invasive Species program and mandatory boat inspection law got a shot of credibility this week as an exotic quagga mussel was found in Montana on the hull of a sailboat that had been in Nevada’s Lake Mead.
Mandatory watercraft inspections kick in at two sites in North Idaho on Tuesday, according to today's SR story.
Montana Fish, Wildlife and Parks officials and a volunteer certified mussel inspector found the quarter-inch mussel Saturday during an inspection at the Dayton Yacht Harbor on Flathead Lake. The mussel appeared to be alive, according to an Associated Press report.
The sailboat had been decontaminated at Lake Mead in Nevada and was inspected by the Idaho Department of Transportation.
Montana officials were notified by the Columbia River Basin Network inspectors last Friday that the decontamination might have been inadequate.
The local inspection led to further decontamination. The boat is in dry dock and won’t be launched for at least two months.
Quagga and zebra mussels can cover beaches with sharp shells, foul boat motors and moorage and overwhelm a lake’s ecosystem.
