Workshop focus is use of Russian River water to combat frost

From the California Farm Bureau Federation:

While the threat of killer frosts is passing, discussions among farmers and other water users in the Russian River watershed about how to protect crops and fish are heating up. Those who divert water from the river, particularly winegrape growers who use water for frost protection, find themselves threatened by agencies that believe frost protection measures could harm salmon.

“While it’s important for farmers to be careful that their diversions do not take endangered species, agencies should not blame frost protection for the recent statewide declines in salmon numbers,” said Jack Rice, California Farm Bureau Federation Natural Resource and Environmental Division associate counsel. “We welcome constructive discussions of this essential agricultural practice and will continue to work on permanent solutions.”

During a packed workshop before the State Water Resources Control Board in Sacramento last week, experts explained why water taken from the Russian River and sprinkled on grapevines during subfreezing temperatures is the best way to protect vineyards.

But others explained that drawing water from the river when watershed flows are low can strand and kill endangered and threatened salmon species. This situation allegedly happened during the worst frost in 30 years in 2008 and, to a degree not yet fully determined, it may have happened again several weeks ago when the area was hit with subfreezing temperatures.

Derek Roy, representing the enforcement arm of the National Marine Fisheries Service, told the state water board last week: “The Endangered Species Act is why we’re here today. Harm is what we’re talking about.” Roy also blamed two fish kills in 2008 on “the cumulative effect of frost prevention pumping practices.” It is important to recognize, however, that these allegations have never been substantiated and totally ignore other potential causes of stranding.
