Name: HUC 8 Dam Storage

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer is comprised of U.S.G.S. sub-basins categorized based on the water storage capacity of dams within the sub-basin (normalized for watershed area) into 'Low', 'Medium-Low', 'Medium-High', and 'High' categories. For more information about how dam storage was calculated, see our <a href='methods/Dam_Storage_methods.pdf' target='_blank'><b>Methods</b><a><font color ="black"> page. </font></br> <br> <img src="img/Dam_storage_thumb.png"> <a href='img/Dam_storage.jpg' target='_blank'><b>View larger image</b><a>
