 * Briones Reservoir

Looking at the things that WikiEdu for asked I will try to do the following: -add information about where the water in the reservoir comes from and goes to     -add information about the trails -I will take more pictures to add to the Wikipedia page as requested.

sources are hard to find and EDMUD itself was not willing to help me because they "do not update their social media" as a representative told me.

Sources https://www.ebmud.com/sites/default/files/pdfs/water-system-revenue-refunding-bonds-series-2009a_2.pdf -this document includes information about the infrastructure that supplies Briones with water.

Bay Nature. Apr-Jun2014, Vol. 14 Issue 2, p16-16. 1/3p. -writes about Bear Creek and how it is dammed by Briones

Briones Reservoir is an open cut terminal water storage reservoir owned and operated by the East Bay Municipal Utility District (EBMUD). It is located in the hills northeast of Orinda, California. It is formed by Briones Dam, an earthen dam completed in 1964. The reservoir is the largest of EBMUD’s five East Bay terminal reservoirs with a total capacity of 60510 acre.ft, and it has a total watershed of 8.59 square miles (22 km²).

Water Source
The Briones Reservoir has two sources for its water. Its watershed of 22km² which includes Bear Creek. Bear Creek once ran down the valley where the reservoir is currently located and still enters the lake in its most Eastern point. Another major, and more important, water source for the Briones Reservoir is imports from the Briones Diversion Works near Orinda through the Briones Aqueduct. This Aqueduct is a 7-foot, 6-inch steel pipe, operated by four pumps that can deliver up to 60 million gallons a day. This is water that originates from EDMUD’s biggest water source: the Mokelumne River. Water drains out of the Briones Reservoir into the San Pablo Reservoir, which is located just in the lower part of the valley. From here, the water is taken into a pumping plant in Kensington.

Recreation
Because the water in the reservoir is mainly for urban use, EBMUD is very strict about recreational activities. Fishing, swimming and wading are not allowed. However, college rowing teams from Mills College, UC Berkeley and Saint Mary's College have permission to use the lake under certain rules. For example, all boats have to be inspected before they are allowed to be used on the lake to prevent contamination. Two trails, the Bear Creek trail and the Oursan trail, form together a 14 mile (23 km) hiking trail that circumnavigates the reservoir. The hike begins at the Bear Creek Staging Area, which is part of Briones Regional Park. A Trail Use Permit issued by EBMUD is required by all hikers, which can be obtained online at the EBMUD website for 10 dollars. No biking is permitted on the trail. Horseback riding is allowed. Dogs are allowed on Oursan Trail segment only and must be leashed.
