Lafayette Reservoir

Notice: Harmful algae present in Lafayette Reservoir

Blue green algae in lakes can result in a buildup of toxins. While near-water activities (picnicking, biking and hiking) are safe, take the following precautions for your safety.

  • Body contact with water is never permitted. Keep children away from the water and the shoreline. Use tap water to rinse any skin that has contacted lake water.
  • Keep pets, especially dogs, out of the water. They should not enter or drink the water.
  • Fish caught here may be consumed after you throw away the guts and liver and rinse fillets with tap water.

Lafayette Reservoir is a recreational reservoir; it is not used for drinking but serves as an emergency supply. For more information, contact EBMUD at 1-866-403-2683.

Rim Trail DetourNotice: Rim Trail detour 

From Fall 2018 to Fall 2019, EBMUD plans to conduct upgrades at the Rheem Reservoir, located off of the Lafayette Reservoir's Rim Trail and Rheem Boulevard. The project will include replacement of the existing roof, recoating the tank's interior, installation of safety stairs, replacement of the drinking fountain and electrical improvements. This project will allow EBMUD to maintain high quality drinking water by updating the reservoir to current standards and improve water service reliability in the area. A portion of the Rim Trail will be inaccessible and a detour will be located at Canyon Trail and Rheem Trail allowing visitors to complete a full loop around the Reservoir. This is to ensure the safety of hikers, bikers and pets during construction. Schedule subject to change.

Notice: Playground closure

 From March 12 to March 28, 2019, the playground will be closed every day for a refurbishment project.

Notice: Partial closure of Lakeside trail  

The western portion of the Lakeside trail has reopened. The eastern segment will be temporarily closed for maintenance until further notice but will remain open on Saturdays and Sundays. All connecting trails and recreation facilities are open.

The Lafayette Recreation Area is an all-year day-use area ideal for hiking, jogging, fishing, boating and picnicking, located off Highway 24 only one mile from the Lafayette BART station.

Things to do


A children's playground is located on the east lawn.


Picnic tables (125) are available on a first-come, first-served basis; 44 have barbeques for cooking your favorite outdoor meals. Four group sites available for reservation; the Large, Stage and Upper sites all accommodate 250 people each. The small site can hold up to 75. Make your online picnic reservation here.


EBMUD plants trout during the fall, winter, and spring months, and plants catfish in the summer. Come to the visitor center to pick up basic fishing tackle and bait to get a line in the water. A daily fishing access permit is required.


Rent rowboats, pedal boats and kayaks at the Visitor Center. If you bring your own boat, there is a launch area (fees apply), and you will need to have your boat inspected to keep EBMUD waterways safe from Quagga mussels. Gasoline engines and trailers are not allowed.


There are two main trails at Lafayette Reservoir. The Lakeside Nature Trail (paved, 2.7 miles) and the Rim Trail (unpaved, 4.7 miles). Additionally, there are 928 acres of open space for hiking, wildlife viewing, photography, and enjoying beautiful vistas.


Bicyclists and people on roller skates, roller blades and scooters are allowed on Tuesdays and Thursdays from noon until closing and on Sundays from opening until 11:00 a.m. on the paved Lakeside Trail and roads.
