Lexington, Mass. (February 26, 2018) –  The Low Impact Hydropower Institute (LIHI) has received a complete application from the Middle Fork Irrigation District (MFID) for the Low Impact Certification of Hydro Plant No. 1 and No. 2 of the Middle Fork Irrigation District Hydroelectric Project located in Parkdale, Oregon (FERC exempt No. P-4458).

LIHI is seeking comment on the MFID application for certification. Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered.  Comments may be submitted to the Institute by e-mail at comments@lowimpacthydro.org with “MFID Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Avenue, Suite 2, Lexington, MA 02420.  Comments must be received at the Institute on or before 5 pm Eastern time on April 27, 2018 to be considered.  All comments will be posted to the web site and the applicant will have an opportunity to respond.  Any response will also be posted.

Project Description

Hydro Plant Nos. 1 and 2 are off-stream conduit facilities that are part of a water transmission system primarily used for irrigation.  Hydro Plant No. 1 contains a single 2.0 MW Pelton turbine, and Hydro Plant No. 2 contains a single 0.5 MW Francis turbine. A third powerhouse, Hydro Plant No. 3, is not included in the LIHI application.  It is located at the outlet of Hydro Plant No. 2 and provides water for multiple uses including hydropower, downstream agricultural uses, the maintenance of a rural fire protection system, and the Bonneville Power Administration fish hatchery facility, which is operated by the Confederated Tribes of the Warm Springs.  Hydro Plant No. 3 ultimately discharges to Rogers Creek, a tributary of the Middle Fork of the Hood River.

The Project was built by the Middle Fork Irrigation District, a District formed in 1921 to meet the irrigation needs of the agricultural community in the upper Hood River Valley. Geographically, the Project is located northeast of Mt. Hood in Parkdale, Oregon, and Project water flows from District points of diversion, northeast towards the Columbia River in Hood River, Oregon.  Flows into the Project begin at Laurance Lake, which has an area of 52.8 acres and a shoreline of 1.6 miles. Laurance Lake, also known as Clear Branch Reservoir, is impounded by the 110-foot high Clear Branch Dam.  Laurance Lake lies in a heavily forested valley with steep ridges on both sides and Mt. Hood to the south. The lake and its drainage basin are entirely within the Mount Hood National Forest land. The reservoir supports an irrigation system that irrigates nearly 6,400 acres of high value crop land in the upper Hood River Valley. The three small powerhouses within the MFID’s Project irrigation system operate under a FERC Exemption for small hydro and were added to the preexisting irrigation distribution system in the mid-1980s.
