Watershed Management

We all live in a watershed. A watershed is a catchment area for all the water that drains from streets, hills and and mountains back toward  lakes, streams, rivers etc. There are four watersheds within Gresham’s boundaries (see a map of Gresham's watersheds). Help protect watersheds with our resident resources and tips.

Watershed Management works to improve flood protection and water quality through the construction and maintenance of the City’s public stormwater system and preservation and restoration of area waterways.
