Caption: This chart shows the number of road crossings per stream mile in all Elk River Calwater Planning Watersheds. Stream crossings can be sources of pollution and pose risk in some locations of catastrophic failure. Road-stream crossings may be under-represented because both streams and road maps are not detailed, so these data should be considered conservative. Data provided by Legacy the Landscape Connection and summary statistics calculated by the Institute for Fisheries Resources. See Info Links for access to more background information.
