Monitor or Propose 303(d) Listing
East Alaska Lake (WBIC: 94200) is currently listed as impaired because of contaminated fish tissue. Major watershed modifications have been installed which has significantly decreased external phosphorus loading to the lake. In 2009, water quality sampling and an aquatic plant survey was completed on East Alaska Lake. This project would be a continuation of the water quality monitoring effort. These data are needed to assess the existing condition of the lake and determine 1). If East Alaska Lake should be added to the 303(d) list in 2012 for additional impairments, and 2). How significant the internal phosphorus loading is to the lake and if an alum treatment is recommended to reduce summer algae blooms.
