Watershed Management

Watershed Series Maps

Watershed Management has mapped detailed boundaries of watershed features in the Anchorage area, generally conforming to NHD defining criteria. All watershed boundaries have been mapped at a high level of detail applying automated and heads-up computer techniques, stereo photo interpretive methods and field checking, and reflecting recent small-scale elevation data and pipes and drainageways mapping. The map views below are depictive—technical users can obtain the latest watershed map data (and metadata summarizing the methods used in mapping these features) from our data library.

Watershed Characterization Maps

Watershed Management has prepared draft Watershed Characterizations for Ship Creek, Chester Creek, Little Campbell Creek and Rabbit Creek watersheds. In these documents, storm drainage and receiving water characteristics of a watershed are mapped and analyzed with the intent to identify specific 'opportunities and constraints' for storm water management strategies within that watershed. A sample series of maps graphically summarizing results for Chester Creek are available below. The complete set of watershed characterization documents can be reviewed at Watershed Management offices.
