Document Description
Canyon Lake was formed in 1928 when the Canyon Lake / Railroad Canyon Dam was constructed. Canyon Lake is located in Riverside County, and is within the City of Canyon Lake. It is owned and operated by the Elsinore Valley Municipal Water District (EVMWD). EVMWD has used the reservoir as a potable water source since 1957 when the Canyon Lake Water Treatment Plant began operation. The reservoir is supplied by stormwater runoff from both the upper San Jacinto River Watershed and Salt Creek watershed. The reservoir, covers approximately 525 acres (212 ha), has 14.9 miles (24.0 km) of shoreline, and has a storage capacity of 11,586 acre-feet (14,291,000 m^3). The lake has three main sections - the relatively shallow East Bay (depths generally less than 10 ft), the deeper Main Lake portion of the lake (depths in excess of 40 ft), and the area north of the causeway that connects with the San Jacinto River. The proposed Project consists of application of alum to Canyon Lake to remove nutrients that contribute to algal blooms. A wide-range of management options, ranging from oxygenation, aeration, mixing, and dredging to application of alum, Phoslock, and other nutrient binders have been considered.
