Data, Facts and Consequences of a Thermal Curtain in Lake Almanor
| data_facts___consequences_of_a_thermal_curtain.pdf |
At one of last year's Town Hall meetings, Wendi Durkin, chair of the task force, presented updates to the community on the state of the 24-year relicensing saga. Wendi’s presentation included information on a draft report recently released by PG&E with over 20 years of data indicating cold water releases from Lake Almanor have not been successful in decreasing temperatures in the lower reaches of the Feather River.
The draft study will go before the Rock Creek Cresta Ecological Resources Committee ERC for comment. The comment period is now open for others.
Conclusions from the study indicate:
• For over 20 years the Rock Creek Cresta Reaches have been watched very closely, visually, and scientifically.
• No impact on the fishery has been see. This section of the Upper North Fork of the Feather River is likely not classified correctly and should be reclassified.
• The measures researched and tested have been exhaustive and costly and found to be ineffective.
• Natural environmental factors like ambient temperatures and sun are responsible for the observed water temperatures in the Rock Creek Crest Reaches.
• PG&E recommends incurring no more customer funded efforts to change the temperature.

The conditions of a new license for the Project, which will be in effect for a period of 40 to 50 years, will have serious impacts on businesses and residents of Lake Almanor. Of greatest concern is that the State Water Resources Control Board (Board) is seeking to require increased cold-water releases, beyond those under the provisions of the April 22, 2004, negotiated Settlement Agreement, as a condition of the new license purportedly to reduce downstream water temperatures for aquatic habitat and to reserve its authority to require the installation of thermal curtains during the new license term.
The Defend Lake Almanor Task Force is working with its partner organizations to call for license conditions that will not require increased cold-water releases from Lake Almanor or installation of thermal curtains at the water intakes that would have devastating impacts to the pristine environment and local economy of the Lake Almanor basin. Damage to existing ecosystems of the Lake Almanor basin will be far greater than the unproven and unquantified gains in downstream aquatic habitat from increased cold-water releases. The Defend Lake Almanor Task Force and its partners are urging FERC not to consider, nor incorporate conditions advanced by the Board into the new license.
