Parent Layer: HUC8 Alteration Assessments

Name: HUC 8 Canal Intensity

Display Field: REGION

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer is comprised of U.S.G.S. sub-basins categorized based on the intesity of canals within the sub-basin (a ratio of total canal length to total stream length) into 'Low', 'Medium-Low', 'Medium-High', and 'High' categories. For more information about how canal intensity was calculated, see our <a href='methods/Canal_Intensity_methods.pdf' target='_blank'><b>Methods</b><a><font color ="black"> page. </font></br> <br> <img src="img/Canals_thumb.png"> <a href='img/Canals.jpg' target='_blank'><b>View larger image</b><a>
