A watershed is an area of land that drains or “sheds” water from rainfall or snowmelt into a specific waterbody. Every lake has a watershed. As water runs over agricultural land and lakeshore development it becomes contaminated with chemicals and sediment. Once this "run-off" drains into a lake it can raise the amount of phosphorus or nutrient pollution. 


Watershed management includes goals such as reducing nutrient pollution from primary sources: fertilizers, animal manure, storm water runoff, failing septic tanks and pet waste.


We are working to raise awareness in addressing our lake's problems.



PHASE I Diagnostic Feasibility Study

Final Report, 1996

"Every opportunity to limit the amount of phosphorous

delivered to the lake should be pursued, so that the

inlake concentrations of phosphorous will be lowered

and consequently, limit the growth of the algae."

Lake Poinsett Watershed
Strategic Plan, 2013

“Lake Poinsett is a lake highly developed for both recreational and commercial purposes. Excessive
algal blooms have historically plagued the lake and hampered recreational uses during the summer
months of the year."

Lake Poinsett Watershed

Implementation Reports I & II

Final Report EPA Section 319 Nonpoint Source
Pollution Control Program

Project Coordinator: RICK SMITH


"The Phosphorus reduction milestone was reached. The current South Dakota Integrated Report lists the lakes in full support of all assigned beneficial uses. Therefore, the project goal was attained."
