ARBOR LAKE
WATERSHED
PROJECT

Check the Map. The watershed is outlined on the map. If you live within the outline, you live in the Arbor Lake Watershed.

The Arbor Lake Watershed Project was developed by Imagine Grinnell and is administered by the Poweshiek Soil & Water Conservation District. Funding is provided by the Iowa Department of Agriculture and Land Stewardship-Division of Soil Conservation, through Water Protection Funds and by the Iowa Department of Natural Resources through a grant from the U.S. Environmental Protection Agency under the Federal Nonpoint Source Management Program (Section 319 of the Clean Water Act). Technical assistance is provided by the U.S. Department of Agriculture, Natural Resources Conservation Service. All SWCD programs and services are offered on a nondiscriminatory basis without regard to race, color, national origin, religion, sex, age, disability, political beliefs, and marital or familial status.

Restore patterns of historic

Treat water as a vital resource


ARBOR LAKE WATERSHED
PROJECT OBJECTIVES

  • Implement Best Management Practice that reduce the amount of sediment and nutrients entering the lake.

  • Initiate an information and education program within the community to both the urban and rural areas.



Working Together To Make The Pieces Fit

All water, except sanitary sewers, within the watershed flows to Arbor Lake. Everything that gets into the water on its All journey (road salt and sand, soil, fertilizers from fields and lawns, trash, pet waste, oil, discarded paint, grass clippings, leaves, and many other things) end up in Arbor Lake.

Even if you do not live in the watershed, you probably conduct business, leisure, or other activities within its boundaries. Check the map again for familiar travel routes, schools attended, work places, businesses you patronize, and places you visit. Everything you do within the watershed affects it in some way.

We all must work together to restore Arbor Lake and keep it clean. Like pieces to a puzzle, each small piece adds up to the whole picture.
