July 20,2021 —Letter from BC Hydro re: Debris and lake levels.
Hi everyone,
I’m reaching out to provide an update on debris collection on Koocanusa Reservoir.
There is a large amount of woody debris in Koocanusa Reservoir this summer, and we know this can be difficult for boaters and tourism operators. Unfortunately, we’re in the second year in a row of challenging environmental conditions that have led to this high volume of debris. The reservoir is at its highest elevation since 2013, which is refloating debris that has been stranded on the shoreline for several years. The heatwave across much of the province has led to rapid snow and glacial melt, which has resulted in a higher reservoir level than forecasted by the U.S. Army Corp of Engineers. This weather pattern has led to more debris than usual in many of BC Hydro’s reservoirs around the province.
As you know, Koocanusa is a reservoir, rather than a lake or river. The dam restricts debris from being naturally flushed downstream. The USACE reports that the reservoir is currently at 2,453.9 feet and it’s likely to peak at 2,454.1 feet around July 26. It is expected to start drafting in early August, and the USACE is targeting 2,449 feet for the end of September.
While BC Hydro doesn’t hold a water license on Koocanusa Reservoir, we have managed and funded debris removal since 1983. The program collects floating debris only and doesn’t include shoreline debris clean-up. Our contractors can’t access floating debris in less than 5 feet of water. We know that some residents have organized their own shoreline clean-ups this season, and we appreciate this extra effort.
The debris contractors, Purcell Environmental, start work early in the morning to collect as much debris as possible before wind and wave action pushes it to the shore. Purcell Environmental has added a second crew to their staff so they can continue clean-up 7 days a week and for longer periods. They’re currently working in the north part of the reservoir and will be moving south through the reservoir this week.
We ask for residents’ patience and understanding as crews work to collect debris. We know it’s challenging for recreational users and tourism businesses and we’re putting much effort into clearing debris as quickly as possible.
Regards,
Sally.
