Name: HUC12 Channelization

Display Field: HU_12_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer is comprised of U.S.G.S. sub-basins categorized based on the intesity of channelization within the sub-basin (a percentage of the length of all streams that has been channelized) into 'Low', 'Medium-Low', 'Medium-High', and 'High' categories.
