July 14, 2012: Avista is advising Spokane River users thatriver recreation is now permitted in the area between the Spokane Street Bridge and the boater safety cables located just upstream of the Post Falls Dam. River flows have dropped sufficiently to allow all of the spill gates at the hydroelectric facility to be closed.
The City of Post Falls boat launch and swim beach at Q’emiln Park is opening to the public today. Typically this occurs sometime between Memorial Day and the July 4 holiday, and on average about June 22.
This year, several factors delayed the closure of the spill gates at Post Falls Dam. The spring runoff season extended well into the month of July, due to a larger than average snowpack and rainfall in June that amounted to more than twice the normal amounts.
Avista’s project to replace the lifting hoists and old timber intake gates at its Post Falls Dam with modern lifting hoists and new steel gates delayed the spill gate closure an additional week. 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 power house at any one time. This means the total river flow had to be lower than normal before the spill gates could be completely closed and the Q’emiln Park boat launch could be opened.
Visitors to Falls Park will see equipment and temporary work structures in and around the river, including cranes, barges, trucks and contractors throughout the project, which is expected to be completed by November. Some areas of the park may be temporarily fenced off, and detours or alternate viewpoints may be designated for park visitors. The public is requested to obey posted signs, stay out of the area of the river below the dam and keep clear of designated work areas.
Avista expects summer operation at the dam to continue through Labor Day, as long as weather conditions allow. River users are cautioned that weather conditions and dam operations can cause rapid changes in water levels. Please exercise caution when using the waterways.
