We’re replacing the lifting hoists and old timber intake gates with modern lifting hoists and new steel gates. The work is expected to update a system that is more than 100 years old in places, enhancing safety and increasing reliability and efficiency at the dam. We were also planning to refurbish the spill gates in the south channel of the river, but that project has been postponed until 2013.
The intake gate replacement project is scheduled for July-November 2012 while river flows are at summer levels. During the project, we’ll do our best to minimize the disruption to recreation and power generation as much as possible, but the work is important so we can continue to safely generate clean, reliable hydropower. The project will affect park users, boaters and dam operations.
Q’emiln Park Boat Launch: During the work, at least two generator units must be taken out of service, which reduces the amount of water that can pass through the powerhouse at any one time. This means the total river flow will need to be lower than normal before the spill gates can be closed and the Q’emiln Park boat launch can be opened. Depending on weather, this will likely take place sometime in mid-July.
Falls Park: Falls Park visitors will see equipment and temporary work structures in and around the river, including cranes, barges, trucks and contractors throughout the project duration. Some areas of the park may be temporarily fenced off, and detours or alternate viewpoints may be designated for park visitors. For your safety, please obey posted signs, stay out of the area of the river below the dam and keep clear of designated work areas.
Post Falls Dam Informational Meeting July 10
Avista will host an informational meeting to discuss the project and answer questions on July 10 from 5:30-7 p.m. at the Post Falls Police Department in Post Falls at 1717 E.
