Water Rights
TID holds historic Water Rights on the Tuolumne River on behalf of our diverse community.
Water is a public trust, owned by the people of the state of California. Water rights are not ownership, but the rights to put that water to use.
In California, water rights are property and can be sold or transferred to willing buyers who can put the water rights to reasonable use.
TID, who jointly owns its water rights with the Modesto Irrigation District, has an assortment of pre- and post-1914 water rights that cover diversion, storage, and power generation. These water rights are the most senior known appropriative water rights on the Tuolumne River — the oldest of which is from 1871.
The District hold these water rights on behalf of the diverse community it represents.
In California, water rights are property and can be sold or transferred to willing buyers who can put the water rights to reasonable use.
The Legal structure around water rights provides certainty and clarity to users of water rights. This certainty has allowed for the development of California water infrastructure over the last 150 years. Some 40 million Californians depend on these investments which have led to California being one of the most prosperous places in the world.
Especially in times of drought, there have been calls to greatly expand and increase the authorities of the State Water Board.
It should be noted that the State Water Board already possesses broad authorities to administer the water rights priority system, including, but not limited to:
TID acknowledges that recent events and an extended drought have highlighted areas in which the State Water Board, in order to more efficiently administer the system, would need to make targeted improvements, including:

TID continually meets or exceeds minimum flow requirements for the Tuolumne River. We always carry over the subsequent year’s fish flow requirements in Don Pedro, hence we do not request Temporary Urgent Change Petitions from the SWRCB (California State Water Resources Control Board) to reduce river releases.
TID regularly files both annual and enhanced water rights reports with regulators. These reports are publicly available.
Real-time diversions and river level data is readily available on our website.
TID’s hydrology modeling and forecasting program is recognized as an industry leader. We regularly invest in new technologies and data collection to improve water management. TID has advocated for state and federal investment in these technologies in addition to seasonal and sub-seasonal forecasting.
