Lafayette Reservoir offers paddling opportunities amid scenic forested shoreline in Contra Costa County. The reservoir features numerous coves to explore and calm waters ideal for family outings. Boat access is managed by EBMUD (East Bay Municipal Utility District), which maintains strict restrictions to prevent invasive mussels - boats from outside California, southern California, and San Benito/Santa Clara counties are not permitted.

The marina rents kayaks, paddle boats, and rowboats, though prices can be high. Only car-top boats measuring 7'10" or longer are allowed to launch, and only electric trolling motors are permitted. Stand-up paddleboards are prohibited. All boats require inspection for zebra/quagga mussels, with a $6 inspection fee valid for 30 days.

Wildlife viewing opportunities include eagles, bobcats, and deer around the 1.4-billion-gallon reservoir's 928 acres of open space. The shoreline features extensive tule reeds, creating diverse habitat areas to explore. Swimming and body contact with the water are strictly prohibited as this is a domestic water supply.

Elevated levels of mercury and PCBs have been detected in fish, so paddlers should be aware of water quality concerns. Operating hours vary seasonally, with summer hours (June/July) running 6:00 AM to 9:00 PM and winter hours (December/January) from 6:30 AM to 5:30 PM.

The reservoir offers several amenities, including restrooms, drinking water, and picnic areas. Multiple trails circumnavigate the water, including the paved 2.7-mile Lakeside Nature Trail. All boats must be off the water by the time the Visitor Center closes, and proper permits are required for launching.
