An Ill-Conceived Hydroelectric Project Would Destroy a Prized Recreational Area


Morrell Canyon, a beautiful oak-filled canyon nestled in the Santa Ana Mountains, is a favored Orange County hiking spot. However, plans to flood the canyon by building a dam and a pump/storage hydroelectric facility threaten this popular gateway to the San Mateo Wilderness and would drown a scenic, unspoiled area of the Santa Ana Mountains.

The proposed hydroelectric scheme would pump water 1,600 feet uphill from Lake Elsinore (to the east, in Riverside County) every night, store it behind the dam, then release it during the day to generate hydroelectric power to sell at daytime peak rates. Morrell Canyon, its creek, and its rare southern coast live oak forest would be drowned beneath two million gallons of polluted water, depriving the public of an irreplaceable recreational area heavily frequented by hikers, bikers, hang-gliders and others.

The project's sponsors - the Elsinore Valley Municipal Water District and Nevada Hydro Company - request for project approval is currently under review by the Federal Energy Regulatory Commission (FERC).

The Sierra Club opposes the proposed hydroelectric project for the following reasons:

  • The project would destroy a gateway to the popular San Mateo Wilderness. Morrell Canyon sits on the edge of the Wilderness and acts as a protective buffer. If the project were approved, hikers would find a 180-foot dam at the Wilderness boundary instead of an oak-filled canyon.
  • Electricity generated by the plant would be connected to lines carried on a series of 190-foot-high transmission towers extending for many miles through the Cleveland National Forest. These towers would be visible from parts of the San Mateo Canyon wilderness and destroy its visual qualities. Construction of the line would impact important wildlife habitat, while high-tension lines present a fire hazard in forest areas.
  • The towers would also destroy a premier hang-gliding site. "Places like this are extremely rare," said Mike Hilberath, vice president of the Elsinore Hang Gliding Association. "We'd like to see a way to improve the transmission of power that doesn't rob people of their enjoyment of public land."
  • The additional power generated by the project can be rendered unessential if California adopts strong power conservation measures to reduce energy demand. The Sierra Club favors the building of smaller power sources close to high demand areas, in a more efficient system of distributed generation and transmission.
  • Release of water by spills or leakage at the dam would introduce lake biota into the canyon below, posing a threat to the downstream ecology.
  • The project would stir up the sediment in Lake Elsinore, worsening water quality in a lake already listed as impaired by the state of California.
  • Fluctuating levels in Lake Elsinore could potentially have adverse effects on shoreline property and on wildlife in the lake.

Hydroelectric Plan Launched in 2004
The threat to Morrell canyon materialized in February, 2004, when the plan was placed before the FERC for approval. In September, 2004 FERC held a series of scoping hearings at which citizens voiced their opposition to the project. FERC is currently reviewing the comments submitted during the scoping process and plans to issue a draft license and Draft Environmental Impact Statement spring of 2006. A three-month comment period will follow the release of these documents. The Sierra Club plans to submit opposing comments.

"Morrell Canyon is a special part of the Cleveland National Forest, full of gorgeous oak trees, brooks, and little waterfalls, and with easy access for families and children," says Robin Everett, a Sierra Club volunteer who hikes here. But if the dam is built, "instead of this oak canyon you would see a giant concrete wall."

Campaign Partners and Supporters
The Sierra Club is only one of several groups opposing EVMWD and Nevada Hydro's Morrell Canyon dam project. Other organizations include:


Public officials who have expressed public opposition to the Morrell Canyon dam include:

  • Mr. Karl Warkomski, mayor, Aliso Viejo, CA
  • Mr. Gus Ayer, city councilmember, Garden Grove, CA
