2 Canyon Lake Dam

3 The basics 383 acres 13.8 miles of shoreline 3 main beaches, additional smaller ones 3 mile championship water ski course (wakeboard, sky ski) Jump Lagoon water ski ramp 2 marinas, 10 common dock areas Concrete dam 80 feet high, 510 feet wide (1929) Dam height 1381.76 feet above sea level


5 Lake Quality Canyon Lake is considered impaired according to the EPA regional standards Levels of phosphorus and nitrogen must be reduced to specific targets by 2020. Levels of dissolved oxygen must be increased to desired targets by 2020. Benchmarks are to be in place by 2015, showing progress to date and a plan for reaching the targets

6 Drainage culvert from QV

7 CLPOA Lake Lease Since 1969, the CLPOA has paid an annual lake lease to EVMWD which now costs $1,200,000 for 2011 for surface rights including swimming, fishing, and boating (body contact) CLPOA operates the lake and provides treatments for algae, fish kill clean up, etc. CLPOA operates two launch areas and 10 common docks CLPOA marine patrol monitors the main lake and East Bay and issues citations for infractions

8 Salt Creek entering Canyon Lake

9 Sedimentation East Bay receives 3 inches a year on average of sedimentation mostly through Salt Creek A dredging project was undertaken in 2003 Goal was removal of 200,000 cu. ft. Operation of the dredge was sporadic Actual removal: 20,000 cu. ft. Two lawsuits stopped the process in 2007 and the CLPOA sold the dredge, returning the money to LESJWA

10 When the water overflows the dam

11 Elsinore Valley Municipal Water District Operates the dam Processes the water from Canyon Lake into drinking water for the district’s customers CL reservoir provides 10% of district drinking water supply Removes as much as 9 million gallons per day for processing when the plant is operating Can remove from 1381.76 feet above sea level to 1372 contractually but usually tries to maintain a level of 1375 Buys water from MWD when necessary, not from the Colorado Rover Aqueduct because of Quagga mussel issues

12 EVMWD Crew

13 Quagga Mussel Program Every boat entering the gates must be inspected for Quagga mussels as of June, 2010 Cost of inspection: $20.00. The program costs the CLPOA $76,000 per year. Wet boats or those from any other water body are red tagged for future inspection Red tagged boats may not be launched before inspection Boats leaving for gas or tune-up only are sealed. If the seal is unbroken they are not inspected. Two live cases so far. Owners cooperated fully. Number of inspections per year: 2583, quarantined 1275

14 Special Enforcement CL Special Enforcement patrols the main lake and east bay by boat on holidays CLSE patrols the North Ski Area by boat every weekend and for special events. CLSE patrols the 800 acres of BLM land on both sides of the North Ski area and the 60 acres around the Jump Lagoon for compliance on foot, on bicycle and by vehicle

15 Special Enforcement: traffic control

16 City NPDES responsibility The city of Canyon Lake is responsible for NPDES compliance Reported spills get immediate action from Special Enforcement and contracted clean up companies Citations are issued if the owner is uncooperative Unreported spills are cited if the owner is eventually reported No major spills on record


18 Rain Events 2004-2005 rain event resulted in closing of the lake from early December, 2004 to early March, 2005 Lake is posted for contamination after each event as a precaution per Health Dept. Testing 72 hours after the last raindrop Tests conducted by lab at EVMWD Signs are removed after test results show no contamination Lake closed by POA when debris is present

19 Holiday Harbor Launch Ramp

20 Salt Creek Flooding

21 Quail Valley Environmental Coalition A 501 c 3 formed in 2010 to raise awareness of the moratorium on building in Quail Valley, the public health threat from failing septic systems, the need for a sewer system in Quail Valley, and the importance of getting the 2006 SARWQRB moratorium on building lifted QVEC works to further the plans of EMWD and the City of Menifee to sewer Area 4 and Area 9 QVEC strives to encourage the city of Menifee to get an emergency plan in place for winter rain events in QV QVEC provides outreach for the QV community on public health and safety issues related to failing septic systems

22 Dr. Anderson’s Analysis Lake is stratified with the lowest stratum anaerobic To reduce phosphorus and nitrogen and increase dissolved oxygen, he modeled the use of alum, aeration and oxygenation The model that would get closest to targets would be oxygenation Conceptual design of a HOS completed by PACE Engineering in 2010

23 Next Steps The TMDL has possible options on what to do to reduce nutrients in CL and no identified funds 1. HOS for the main lake paid for by a credit system for nutrient producers in the watershed 2. The use of PHOSLOK, a chemical treatment that binds phosphorus and captures it at the lowest layer of the lake strata 3. The East Bay will have to be dredged at some point. The SARWQB will decide which approach will be approved

24 No diving, no jumping
