Along with the clear-running creek water well water was the mainstay of Timber Cove settlers throughout the 19th and early 20th Century. Often the well water was found to contain iron and manganese.

     A Mutual Water Company was formed on January 31, 1978 to provide water to Timber Cove residents. On August 1, 1984, this company transferred its rights to the Timber Cove County Water District, formed by the Sonoma County Board of Supervisors on April 24, 1984. Among the transferred assets were wells on Cundall Court, Lyons Court, Signaigo Way, and Ruoff Drive.

     TCCWD is formed under the California Water Code §31000-31016.

     The District issued two bonds in 1994 (1994A and 1994B) which included an existing bond issued about 1986. The purpose of all of these bonds was to develop the distribution system. 1994A was for $1,128,828.76 and matured in 2009. 1994B is the California State loan which also included a $400,000 grant from the State of California. Bond 1994B, for $437,164.32, will retire in 2019.

​    The District has two permits to take water from Timber Cove Creek and purchased the site of its creek wells from Caltrans in 2015. The district now provides water to about 270 customers and supports water flow to fire hydrants. A Watershed Sanitary Survey conducted by Forsgren Associates was published December 2011. A Distribution System Evaluation was performed by Brelje and Race Consulting Engineers in December 2011.
