To hear the Modesto Irrigation District tell it, selling 2,000,000 gallons per day of Tuolumne River Water will have no significant impacts on the river. Stanislaus County Supervisor and Westside farmer Jim DeMartini finds such a claim hard to believe.
“I just had my water allotment reduced by fifty percent,” said DeMartini recently. “I get my water from the Turlock Irrigation District (TID) and TID gets its water from the Tuolumne River, the same source as the MID.”
DeMartini isn’t the only one who thinks the MID has overstated the Tuolumne’s capacity for water deliveries. Former Palo Alto Mayor Peter Drekmeier is the Bay Area Director for the Tuolumne River Trust. The Trust works closely with the San Francisco Public Utilities Commission (SFPUC) and a host of other agencies to insure the health of the river and associated ecosystems. On March 28, Drekmeier sent a letter to SFPUC expressing “serious concerns about the proposed water transfer.”
Drekmeier’s letter lists a number of issues the MID has either overlooked or ignored in its “excess water” scenario. Among the most damaging factors to the MID assessment, Drekmeier noted that the water transfer relies on, “stale baseline data regarding biological resources dependent on the Tuolumne River below O’Shaughnessy Dam.”
Moreover, especially since the Tuolumne has been added to the Environmental Protection Agency’s “Impaired Waters” list, most experts expect the Federal Energy Regulatory Commission to require enhanced flows on the lower Tuolumne River when it completes its relicensing process in 2016. That means in the very near future, less water will be available higher up on the river.
The most frightening section of Drekmeier’s letter summarizes a report generated by the SFPUC itself. Titled, “Sensitivity of Upper Tuolumne River Flow to Climate Change Scenarios,” the report concludes that in “critically dry years” runoff at Hetch Hetchy could decrease up to, “46.5% by from present day conditions,” by the year 2100. In the interim, there will most likely be a steady decline in runoff.
There was a time in the not too distant past when few people cared about water issues and even fewer understood them. Those days are gone. Farmers like Jim DeMartini have learned losing the water wars means losing the farm, so they’ve become both expert and vigilant on water issues. The Tuolumne River Trust Board of Directors and Advisors include a “Who’s Who” list of prominent and informed citizens, all of them keenly aware of the west’s rapidly diminishing water supply.
Given these realities, it’s hard to fathom why the MID has arrived at its “excess water” scenario, but one thing’s for certain: MID Directors have a lot of explaining to do.

With all very sincere respect for Director Larry Byrd, the rest of the Directees simply
have not demonstrated the capacity to understand either the issues or the arithmetic
involved in this matter, and hence lack the ability to do any, let alone a lot, of

I think an article on the re-licensing, and what people can do, would be great.
