  3. 3. Grand Lake St. Marys Current Condition GLSM is very hypereutrophic : Hypereutrophic is defined by having Total Phosphorus (TP) > 100 mg/L Chlorophyll a (Chl) > 50 mg/L GLSM has summer TP that ranges from TP ~ 170 to 200 mg/L GLSM has Chl that can reach Chl ~ 250 mg/L 3
  4. 4. Sources of Phosphorus to GLSMExternal P Sources Include: Agricultural Landscape All land-uses including yards Infrastructure – roads/builds/homes Wildlife Streams and Rivers Atmosphere GroundwaterInternal P Sources Lake Sediments Lake Biota – fish, algae, plants, waterfowl 4
