Lake Improvement Association
The purpose of the Lake Improvement Association is to promote closer fellowship and cooperation among farmers, landing owners and park operators; to advance the general improvement of the lake, its shores, channels, creeks, landings, parks and land in order to promote good health, soil stability, and clean, wholesome recreation for the public and private use of the area adjacent to the shores of the Grand Lake St. Marys, located in Mercer and Auglaize counties in the State of Ohio.

GLSM has a problem… Too much phosphorus!
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
4
Sources of Phosphorus to GLSM
External P Sources Include: Agricultural Landscape All land-uses including yards
Infrastructure – roads/builds/homesWildlife Streams and Rivers AtmosphereGroundwater
Internal P Sources Lake Sediments Lake Biota – fish, algae, plants,
waterfowl
6
Ecological Sustainability of GLSM is Dependent Upon External Phosphorus Load Reduction and Continued Management
How to speed the lake recovery along while watershed sources are controlled?
Reduce in-lake phosphorus concentrations
