“Peak” isn’t a common desert term, except at Moses Lake, a 6,800-acre splash among sand dunes where biologists have documented peak walleye populations, and the season’s peak walleye feeding activity is late May and early June.
Nearby Potholes Reservoir also produces good walleye fishing, along with a range of other fish including net-pen rainbows.
Walleye limits are liberal at these lakes, yet the fish range into the teens.
“Hot spots tend to move around since the voracious post-spawn predators eat themselves out of house and home,” said John Carruth, tournament angler from Davenport.
At Moses Lake, check out these areas:
•Rocky Ford Creek mouth at the north end of the lake, where walleyes generally are in 8-10 feet of water except in low light conditions, when they might be as shallow as two feet.
•McConnahie Flat just uplake from Conully Park.
•Heron Island (north of Interstate 90) and the rock shelf that extends north.
•Goat Island in the Pelican Horn (south of I-90) at the easternmost part of the lake and the entire area off the Peninsula boat launch.
In mid-April, check out Parker Horn, where walleye move into spawn in the waters coming in from Crab Creek.
This is one of the few shoreline fisheries for walleye. It’s accessible from Alder Street.
Some anglers cast plugs downstream, others look as though they’re steelheading by bottom bouncing jigs with a No. 6 hook and 2-inch grub.
Go at night and you can see walleye eyes glowing in the streetlights.
