Nicola River Freshet Update – May 22, 2020 6:00 PM
There have been no changes made at the Nicola Lake Dam today. The Nicola Basin has received precipitation over the last 36 hours. As a result of the rain, Mill Creek flows have increased, which has resulted in Nicola River levels rising by ~1.5 inches over the course of the day. Streams that feed the Nicola Lake, such as Quilchena Creek, the Upper Nicola River and Pennask Creek, have continued to recede, though the rain has caused the rate of recession to slow.
The City has been informed by the dam operator that at the current rates of Nicola Lake rise, inflows will need to match outflows within the next 2-5 days, as the lake is very near its maximum capacity. With less rain forecasted over that period, this will ideally be achieved by holding outflow steady and seeing a steady decrease in inflows. However, if inflows don’t come down sufficiently over that period, there is still the possibility that further gate changes will be required, which could lead to flooding for some residents.
Over the weekend, we will continue to monitor the river system closely and will provide you with prompt updates if we receive notice of a gate change, or if we see a change in conditions that could necessitate a gate change.
