 In 2006 residents of the lake asked the Alaska Department of Fish and Game (ADF&G) for help in removing northern pike from the lake and initial planning began resulting in the application of the fish poison rotenone in 2009 to restore the fishery.In 2010 surveys confirmed that the lake was free of northern pike and ADF&G restocked the lake with rainbow trout, Arctic char, and Arctic grayling.In July 2011 an invasive aquatic plant, Elodea, was discovered in dense growths in Sand Lake as well as nearby DeLong and Little Campbell Lakes.
