The spring runoff season is just beginning, and can create dangerous river flows and lake levels. Stay safe by staying out of the water during high flows.

The high river flows and lake levels we saw in the first week of April brought breathtaking views at our area dams along with water over some parts of our roads and trails. This may have you thinking we’re well into the spring runoff season. But the fact is what we saw earlier this month was just a preview of what’s to come.
An abundance of early spring rain rapidly increased the flow of water into Coeur d’Alene Lake, and from there, into the Spokane River in the last days of March and early part of April. The Spokane River peaked on April 3 with nearly 28,000 cubic feet per second flowing through downtown Spokane, while Coeur d’Alene Lake peaked at just over 2,131 feet above sea level, or about 3 feet above its normal summer level. Since then, river and lake levels have gradually fallen, remaining fairly steady for the last few days.
Today (April 13), they’re starting to rise slightly again – and we’re likely in for a couple more months of high waters. Due to higher than normal seasonal snowpack (as of Friday April 13, it’s still at 108 percent of normal), and warmer expected temperatures in addition to the heavy rainfall we’ve already received, the National Weather Service is predicting above average river flows in the area in the coming months.
Safety is a top priority at Avista. So as warmer, sunny days draw you to the water, we want to remind you that Coeur d’Alene Lake and the downstream river and reservoir levels can change rapidly at any time, due to weather and other factors. Please use caution on the water and comply with all posted notices and closures, especially near the vicinity of hydroelectric facilities, and always wear your life jacket when on the water.
Property owners and lake users – remember to make necessary preparations, including removing boats from the water, and removing or securing docks and boathouses to accommodate changing water conditions.
When recreating on or along a river or reservoir, always follow these important safety tips:
• Always be alert for debris, obstructions, and partially submerged objects.
• Always obey warning signs near dams.
• Never cross boater restraining cables or buoy lines that designate areas where boats should not operate.
• Never fish, swim or boat above or below a dam - water levels can change rapidly with little warning due to operation of spill gates and turbines.
• If in a sailboat or catamaran, always look for overhead cables and power lines.
• Always wear personal flotation devices (PFDs), even if you are an adult.
• Never operate watercraft under the influence of drugs or alcohol.
• When on the water, obey all warning signs and follow all rules and regulations.
