School’s out and the weather is finally beginning to warm, which will have many of you making summer river and lake recreation plans. Before you head out for fun on the water, we would like to provide you with information about current river flows and lake levels, as well as our plans for summer operations at Post Falls Dam.
The amount of snow in the mountains continues to be well above normal, because the cool weather has slowed the snow melt. At the beginning of June, Avista began closing spill gates at Post Falls Dam. However, above normal June rainfall has again pushed Lake Coeur d’Alene above its summer elevation. Avista has had to re-open all spill gates and current flows in the Spokane River are more than twice the volume we would normally expect this time of year.
With snowpack still over 200 percent of normal for the Spokane River basin, and a forecast of cooler and wetter than average weather, the runoff is expected to continue well into the summer.
Avista will likely be spilling excess water over the spillways at Post Fall Dam until after the Fourth of July holiday this year. Because of the open spill gates, the river upstream of Post Falls Dam will continue to be lower than normal until after the runoff season, and the City of Post Falls boat launch at Q’emiln Park will not open until after July 4th. Typically this occurs sometime between Memorial Day and mid-July. The median date for closing the gates is June 22.
Avista operates our hydroelectric facilities with a focus on several different objectives:
Meeting customer demand with reliable energy service
Operating safely and efficiently
Complying with local, federal and state regulations and laws
Being good environmental stewards
Providing recreation opportunities
Safety on the river
As always, we ask you to exercise caution on the water, as river and lake levels can change at any time depending on weather and other factors. The water is still cold, which puts those who are recreating on or near a lake or river at risk for hypothermia, even in warmer weather. Here is some other important safety information for your consideration:
Always wear a lifejacket on the water.
Obey all safety and warning signs.
Never fish, play or anchor your boat below a dam.
Sudden discharges can increase water flows in a hurry.
Don’t cross the boater safety cable above a dam. The current could pull you through a spill gate or drag you under water near a powerhouse.
Watch overhead clearances like cables and power lines when sailing.
The best way to get the latest information on anticipated elevation changes on Coeur d’Alene Lake, Lake Spokane, and the Spokane River is to call Avista’s 24-hour telephone information line.
In Idaho, call (208) 769-1357; in Washington, call (509) 495-8043.
The recorded information is provided to advise shoreline property owners, commercial and recreational users of changes in lake and river elevation levels that may affect plans for water use.
You can also check current river and lake levels on our website. Property owners and lake users are reminded to make necessary preparations, including removing boats from the water, and removing or securing docks and boathouses to accommodate changing water conditions.
