Canyon Watershed is located north of the Cal Poly campus up from
Indonesian Reservoir next to (#14) on Caballo Peak. The USGS (United
States Geologic Service) defines a watershed as all precipitation
that falls within a topographic area and can contribute to streamflow
exiting the watershed outlet. Watersheds are useful for land designation
purposes by forming natural boundaries. Horse Canyon Watershed
is one of the larger watersheds on Cal Poly's land.
