Location & official information
Public marina and launch
Diamond Valley Lake Marina operates the public launch ramp, small-boat rentals, and support facilities on behalf of the Metropolitan Water District. Operating days and seasonal hours vary — confirm on the official page before towing.
Clean-drain-dry and inspection
As a drinking-water reservoir, DVL enforces clean-drain-dry rules for trailered vessels and screens for invasive species. Vessel-eligibility rules (size, hull type) are set by MWD and the marina operator.
Body-contact prohibition
Swimming, wading, water-skiing, wakeboarding, and personal watercraft are prohibited to protect drinking-water quality. Fishing and permitted boating are the primary on-water uses.
Operating schedule caveat
Operating days and access can change; historically DVL has not always been open every day of the week. Always confirm current schedule with the operator before planning a trip.
Hemet / Riverside County context
DVL sits near Hemet in Riverside County. Access is via SR-79 and local roads; the park adjoins the Southwest Riverside County Multi-Species Reserve.
Boat-owner care considerations
Inland dust, hard water, and strong sun are the recurring stressors. Owners typically maintain boats at home between visits and manage light spotting after each trip.

Frequently asked questions
Does listing here mean the harbor endorses Boat Detailing LA?
No. Directory pages are editorial context for boat owners. We are not affiliated with any marina, harbor, harbor district, or yacht club unless we explicitly say so, and no listing implies endorsement, partnership, or preferred-vendor status.
Do you service boats at this location?
In most cases, yes — service is confirmed by the boat’s exact slip or storage location and the marina’s vendor-access rules. We coordinate access after your estimate request and before scheduling anything on the dock.
Where does the information on this page come from?
Facts on this page come from the operating agency’s official website (linked below). We only publish details we can verify from an authoritative public source, and we mark when the record was last reviewed.
Can I swim or ski at Diamond Valley Lake?
No. Because DVL is a drinking-water reservoir, body-contact uses — swimming, wading, water skiing, wakeboarding, and personal watercraft — are prohibited.
Is DVL open every day?
Historically DVL has not been open every day of the week. Check the operator’s current schedule before planning a trip.
