LEWISTON, Idaho — Federal officials say they intend to restart a project aimed at adding liquid fertilizer to the Dworshak Reservoir in hopes of growing bigger fish.
The U.S. Army Corps of Engineers released an environmental study Monday saying the addition of liquid fertilizer would not have a significant impact on the 55-mile long lake in north central Idaho.
Dworshak Reservoir Resource Manager Paul Spence told the Lewiston Tribune he hopes to get staff working on an application this week.
In 2007, the corps and Idaho Department of Fish and Game started adding fertilizer to the reservoir as part of a five-year pilot project.
The goal was to balance nitrogen and phosphorus levels and boost growth at the bottom of the lake’s food chain — and ultimately the growth of kokanee salmon.
