Currently, Flint Lake’s main nuisance aquatic plant is curly-leaf pondweed (Potamogeton crispus), with small scattered beds of Eurasian watermilfoil {Myriophyllum spicatum). Long Lake, is 65 acres with a maximum depth of 26 ft and an average depth of 8 feet and connected to Flint Lake by a channel on the south end of the lake.

The Valparaiso Lakes Area Conservancy District {VLACD) was granted cost-share assistance from the Indiana DNR (INDNR) Lake and River Enhancement program (LARE). The initial Aquatic Vegetation Management Plan (AVMP) was completed in 2006 and established specific goals to reduce and control invasive plant life in Flint and Long Lakes while maintaining diverse and flourishing native plant population.
