A team of partners from the Lake Tahoe Aquatic Invasive Species Program is scheduled to begin implementation of an “Asian clam control” project this month at Lake Tahoe Nevada State Park, Sand Harbor. The goal is to treat a small, isolated population of Asian clams at Sand Harbor before they spread. They will cover about 4 acres of the lake bottom near the boat ramp, with thin rubber barriers. Steel rebar on top of the barriers keeps them in place and deprives the clam population of oxygen. Tears or other damage to the mats will reduce their effectiveness, so they’re asking boaters to not anchor on top of mats, sand bags or rebar.
