Security Barriers Reduce Boat Access at Brownlee; Work Impacts Boat Ramp

Final installation of floating security barriers is underway. Removal of heavy equipment will restrict public access to the Woodhead Park boat launch through March 1.

CAMBRIDGE, Idaho—Idaho Power has nearly completed installing floating boat barriers above and below Brownlee Dam, meaning boaters can no longer access the area immediately downstream of the dam or approach the upstream side.

The contractor who installed the barriers will be removing equipment and materials Feb. 24–March 1 using the boat ramp and parking area at Woodhead Park. Public access to the boat launch will be restricted to the old launch, just south of the new one.

The new barriers will prevent boats from getting within 600 feet of the dam on the upstream side and within 1,000 feet on the downstream side. The barriers will not impact streambank access to the river.

Idaho Power operates the dam and power plant to generate electricity. The dam also serves a key role in spring flood-control operations overseen by the U.S. Army Corps of Engineers. The Brownlee project is considered critical electrical infrastructure.

The company is required to meet security standards established by the federal government to protect critical electrical infrastructure against potential attacks. One part of meeting these requirements is controlling water access near the dam and power plant. After evaluating many options and consulting with other hydropower facilities, Idaho Power determined that floating barriers are the best solution.

These security improvements protect electrical infrastructure critical to both the regional energy grid and to Idaho Power’s customers in Idaho and Oregon. Idaho Power understands the impact this has on the boating public, and the company remains committed to providing recreational access to the Snake River throughout our service area and providing reliable, affordable, clean energy.
