FERC on Jan. 28 released a final environmental impact statement for relicensing the 84.8 MW Bucks Creek hydropower project in California's Plumas County.

Washington's Department of Ecology on Dec. 30 adopted revisions to its water quality standards that will allow operators of the eight lower dams on the Snake and Columbia rivers and five mid-Columbia dams to increase spill that would create up to 125 percent total dissolved gas saturation du…

FERC staff on Oct. 30 issued the final environmental assessment for a proposed 5 MW pumped-storage hydro project on the Columbia River, concluding its potential environmental impacts, with "appropriate" protective measures, would not "significantly affect the quality of the human environment."

The Trump administration finalized repeal of the 2015 "Waters of the U.S." rule effective Dec. 23, reverting to previous regulations, according to a Federal Register notice EPA and the U.S. Army Corps of Engineers published Oct. 22.

A June report from the Department of Interior’s Inspector General found “significant control weaknesses” in account management and personnel security practices at two of five U.S. Bureau of Reclamation dams that are considered national critical infrastructure.

The U.S. Senate on June 28 passed a bill from Sen. Lisa Murkowski (R-Alaska) extending hydropower preliminary permit time frames, seeking to improve the Federal Energy Regulatory Commission’s preliminary permit licensing process. The Senate also passed the same day a number of other bills an…

Hydropower generation in California picked up substantially in 2016, but still fell short of a peak hit in the state in 2011. Gross generation from hydro facilities edged up to just over 30 million MWh last year, up substantially from about 12 million MWh in 2015 (see chart at right).

The U.S. Army Corps of Engineers is now proposing underwater construction instead of a one- to two-year drawdown to build a water temperature control tower and fish collection structure at Detroit Dam on the North Santiam River southeast of Salem, Ore.

A federal judge has denied a request from three environmental groups to order additional drawdowns and spills at Willamette Valley projects, saying they were unable to show that irreparable harm to Endangered Species Act-listed fish would occur without a preliminary injunction.

The Federal Energy Regulatory Commission on April 18 approved a rule establishing voluntary ­processes for expedited licensing of hydroelectric facilities at ­nonpowered dams and closed-loop pumped storage projects.

The enactment of the Washington Clean Energy Transformation Act on May 7 expanded hydropower’s role in addressing the decarbonization of the state’s power supply, by letting it directly count toward the act’s 2030 carbon-neutral and 2045 carbon-free mandates.

The newly reconstructed main spillway of Oroville Dam was opened April 2, returning it to normal ­operation for the first time since February 2017, when record winter rains in California increased the reservoir level to its full 901-foot capacity and severely damaged it and the ­emergency sp…

The U.S. Army Corps of Engineers is ­reviewing public comment submitted on its plan to build a ­downstream fish-passage facility at Cougar Dam in the upper Willamette River basin, about 42 miles east of Eugene, Ore.

The newly reconstructed main spillway of Oroville Dam was opened April 2, returning it to normal operation for the first time since February 2017, when record winter rains in California increased the reservoir level to its full 901-foot capacity and severely damaged it and the emergency spil…

Bids are due March 26 for Chelan County PUD’s latest auction of up to 5 percent of the output from its Rocky Reach and Rock Island hydroelectric projects, for either a 2.5-percent slice or for the entire 5-percent slice.

The California Independent System Operator issued its draft final proposal for a series of enhancements to its market-power mitigation rules aimed at several issues that have developed, particularly for hydroelectric resources operating in the Western Energy Imbalance Market.

Bids are due March 26 for Chelan County PUD’s latest auction of up to 5 percent of the output from its Rocky Reach and Rock Island hydroelectric projects, for either a 2.5-percent slice or for the entire 5-percent slice.

California regulators should require Pacific Gas & Electric to spread the projected losses from its sale of the 5.7-MW Deer Creek hydroelectric project to the Nevada Irrigation District over several years, The Utility Reform Network said.

A proposal to modify Washington state’s total dissolved gas standards to 120 percent in both forebays and tailraces at eight dams this year would allow for more spill and reduce powerhouse encounters by salmon and steelhead smolts, which should eventually result in more adult returns.

Dozens of comments from the public and environmental groups ask the Washington Department of Ecology to exercise its authority under the federal Clean Water Act to address rising water temperatures in the Snake and Columbia rivers caused by dams and climate change.

The Northwest Power and Conservation Council got a first-hand explanation from the federal agencies, states and tribes involved in a flexible spill agreement that goes into effect in April, if Washington state modifies its total dissolved gas limits.
