RESERVOIRS -- As the water level in Lake Roosevelt continues to rise behind Grand Coulee Dam, more boat ramps are becoming viable again and anglers are becoming more versatile.
A nifty new NOAA hydrograph web page helps boaters with constantly updated information on lake levels, projected elevation changes and boat ramp launching levels. It also shows when the lake is too low for running the Gifford and Keller Ferries.
"I recently added low-water impacts to the web page with the short term Lake Roosevelt forecast to help prevent more recreationists from hauling their boats out only to find their ramp high and dry," said Katherine Rowden, the National Weather Service hydrologist who helped worked up the site.
"The 'Low Flow' line on the hydrograph is when the Gifford Ferry stops running (first significant impact), but if you scroll down below the map, I've also listed all the boat ramps (per elevations on the Park Service's website) so folks can match up current and forecasted levels if they have a certain spot they like to launch from.
"The forecast is updated daily and incorporates planned reservoir operations."
