-map of anoxic area of Threemile Pond
-46%of surface area of lake is over anoxic water
-levels below 1ppm can cause phosphorus release from sediments
which in turn can cause algal blooms
-and cause fish kills
-- -low levels of do indicate poor water quality
-these anoxic conditions could cause problems for the fisheries in TMP
