Water Resources

Across our urban and rural communities, Polk County has committed to working with our water resources.  Improving water quality, creating recreational resources and addressing flood challenges all play a key role in reaching a vision for improving water resources in Central Iowa.  From the Raccoon River to Fourmile Creek, all of our water resources require their own unique effort.  Polk County has committed to following the watershed approach to understand our unique resources and achieve our goals.
