Topic	Sediment: Road Densities for Rockpile Creek Calwaters

 

Caption:  The Chart above shows the density of roads in miles per square mile for Rockpile Creek basin Calwaters. The highest road densities are in the Red Rock (7.5 mi/sq mi) Middle Rockpile Creek (5.9 mi/sq mi) and Lower Rockpile Creek (5.9 mi/sq mi) Calwater areas and are associated with timber harvest. The Upper Rockpile Creek Calwater has lower road densities because it is largely within the Central Belt Franciscan Formation, which makes it difficult to build and maintain roads. The threshold of 3 miles per square mile comes from Cedarholm et al. (1984). Roads mapped by UC Davis ICE for NCRWQCB as part of TMDL and densities calculated by KRIS IFR staff. See Info Links for more information. See Picture for a map of roads in this area from the KRIS Gualala Map project.
