Caption: This chart shows the road density within all Elk River Calwater Planning Watersheds as miles of road per square mile of watershed. Although Lower Elk River (Low Elk) has some suburban development, most roads in the Elk River watershed are related to timber harvest. Roads on timberlands may not reflect skid trails, temporary roads or tractor trails and so should be viewed as conservative. Proper watershed function for salmonid habitat according to National Marine Fisheries Service (1996) is 2.5 miles per square mile, which is shown as a reference above. Data from Legacy the Landscape Connection with summary statistics generated by the Institute for Fisheries Resources. See Info Links for access to more background information.
