North Central Storm Water Project

Project Overview
The North Central Storm Water Project was designed to relieve overland flooding in the area of Storm Lake that is north of the Storm Lake High School from Spooner St. on the west and to Russell Street on the east. The project will also collect and treat run off from the residential sub-division that includes Walnut, Oak, and Hickory Lanes around East 9th Street and East 8th Street.

The project when finished will use the current best management practices to collect and control storm water in a way that will filter the water prior to out letting the water to Poor Farm Creek to the north of Storm Lake.
