 | | The biomass in South Duck Lake appears to be increasing and approaching that measured in Mid-Duck Lake. |
 | | Lakes infested include, but are not necessarily limited to: Duck Lake, Ocean Shores; Lake Limerick, Mason County; Big Lake, Skagit County; Silver Lake, Cowlitz County; Leland Lake, Jefferson County; Ohop Lake, Pierce County; Lacamas Lake and Battleground Lake, Clark County; Fenwick Lake, King County, Loomis Lake and Black Lake, Pacific County. |
 | | However, the 2000 spring survey showed that the mean biomass of Egeria densa in the lake was still only 11 percent of the biomass present in the lake before treatment and five years after the whole lake Sonar® treatment. |
