Stormwater Outfall Inventory

This inventory involves identifying and mapping stormwater “outfalls” – every point where a conveyance of stormwater system discharges into streams, lakes, and wetlands. More than 1600 outfalls have been identified in Portage

Portage County Stormwater District’s Outfall Inventory Manual describes the process for conducting the inventory and contains relevant mapping. Specific attributes (receiving stream, pipe shape, etc.) were collected for each outfall. It was noted whether flow is present in dry weather, which may point to a pollution source upstream
