Jul 06 , 2010 Water levels allow spill gates at Post Falls Dam to be closed
Avista is advising Spokane River users that river recreation is now permitted in the area between the Spokane Street Bridge and the Post Falls Dam. River volumes have dropped sufficiently to allow the spill gates at the dam to be closed.
The City of Post Falls boat launch at Q’emiln Park is expected to be opened to the public today. Typically this occurs sometime between Memorial Day and the July 4 holiday. The median date for closing the gates is June 22; however the date has occurred as late as July 8 in 2008 and as early as May 22 in 2005.
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 can cause rapid changes in water levels. Please exercise caution when using the waterways.

High water conditions require open spill gates at Post Falls Dam
Avista is advising Spokane River users that boating and swimming remain prohibited in the area between the Spokane Street Bridge and the Post Falls Dam through the holiday weekend. Last week’s heavy rainfall in North Idaho has resulted in higher than normal flows in the Spokane River and Avista must spill the extra water. Because of the open spill gates, it is not safe to be in the water above the dam and a Post Falls city ordinance prevents river use in that area.
Once the spill gates can be closed the Q’emiln Park boat launch will be opened and river recreation can resume. Typically this occurs sometime between Memorial Day and the July 4 holiday. In recent years the median date for closing the gates has been June 18, however the date has occurred as late as July 8 in 2008 and as early as May 22 in 2005.
Avista expects to begin summer operation at the dam as soon as weather conditions allow.
The river above the Spokane Street Bridge and Coeur d’Alene Lake are accessible with several relatively close public boat launches open. They include the launch at Blackwell Island, Third Street Launch, Higgins Point, Boothe’s Landing and Mica Bay.

Heavy rains require action, lowering of river
Avista will need to open additional gates at the Post Falls Dam today to allow the increased flow in the Spokane River to pass by the dam. This action is due to a large amount of rain in the North Idaho mountains over the last 24 hours which is causing Coeur d’Alene Lake to rise.
Avista is waiting to open the biggest gate until this afternoon to allow Spokane River users to move their boats and equipment to a safe location in the river. The elevation of the river near the Spokane Street Bridge this morning is about 2,124.8 ft., which is about 3 feet below summer level. Once the bigger spill gate is opened the river level will drop as much as 7 feet below summer level.
Coeur d’Alene Lake is currently slightly above its normal summer level of 2,128 ft. above sea level which Avista is required to maintain until after Labor Day.
As more water flows in the Spokane River between the lake and the dam, Avista must open more spill gates to allow the water to pass so that the lake remains at or near 2,128. The more spill gates that are open, the lower the elevation of the water above the dam, near the Spokane Street Bridge.
Boaters and other river users are reminded that weather conditions can cause rapid changes in river levels. Please exercise caution on the water.

Post Falls Dam on the Spokane River. |
This has been quite a year for unusual weather. All the rain we’ve had is increasing the flow of water into Coeur d’Alene Lake. Our federal license doesn’t permit us to let the lake go above its summer level of 2,128 ft. above sea level. So to keep that from happening we’ve been letting as much water as possible spill over the dam at Post Falls. When the river runs fast, as it is now, this causes the water level to drop in the stretch of the Spokane River upstream of the dam.
If the weather cooperates the river should start to rise later this week. And even though this is an unusual year for weather, it’s normal for the river to fluctuate until around the Fourth of July, when we are typically able to close the spill gates at the dam and hold the lake level steady.
We’re looking at some ways to improve communications with river users, but please remember that conditions can change very quickly and use caution on the water.

We're always pleased when we can get out the word about safety on the bodies of water that our dams are connected with. Yesterday, KXLY reporter Jeff Humphrey did a good story on Avista raising the levels on Lake Coeur d'Alene in conjunction with low spring runoff.
If you're a recreational boater, that might mean you'll be able to use the lake earlier than in previous years. But with these early changes comes the dangers hidden under the water - such as rocks or wooden pilings, so watch out.

Weather conditions dictate unusual water levels
Avista is urging boaters to be extra careful when navigating the Spokane River above Post Falls this spring. Because of low snow pack in the watershed, the river may be at unusual levels until after the runoff is completed.
Current water levels are between normal winter and summer seasonal elevations and the water is rising slowly. Boaters should be alert for shallow areas that can contain hidden obstacles such as rocks or wooden pilings.
The river and Coeur d’Alene Lake are expected to return to the normal summer level of 2,128 feet above sea level after the runoff is complete. Weather conditions will determine how quickly a return to summer elevation can occur.

Years ago, I spent a few summers boating the St. Joe River and lower part of Coeur d’Alene Lake, which includes Chatcolet, Round, Benewah and Hidden Lakes. In fact, I learned to water-ski on the St. Joe, known for its glass-smooth surface and calm waters. In those days I didn’t give much thought to the river banks – beyond wondering where exactly the river ends and the lake begins.
Last week, I had the enlightening experience of seeing first-hand some of the long-term impacts of hydroelectricity, boating and other uses of the lake and river, when I joined a group touring a two-year shoreline erosion inventory and assessment on the St. Joe River where it flows through this lower portion of Coeur d’Alene Lake.
Avista and the Coeur d’Alene tribe are working together on this erosion study, one of the first of three major phases in our erosion measures within the Tribal waters of Coeur d’Alene Lake, and a condition of Avista’s 50-year FERC license to operate its Spokane River hydroelectric project. The study is also part of the comprehensive settlement reached between Avista and the Coeur d’Alene tribe prior to last year’s issuance of the license. In addition to compensating the Tribe for past and future storage of water, the settlement requires Avista to pay a total of $100 million into the Coeur d’Alene resource protection trust fund for costs associated with environmental measures in and around Coeur d’Alene Lake. This funding mechanism allows the Tribe and Avista to collaborate on complying with license requirements, which include this shoreline erosion control project, as well as activities in wetland restoration, water quality monitoring, aquatic weed management and protection of cultural resources on the reservation.
Dave Lamb of the Coeur d’Alene Tribe and Bruce Stoker of Earth Systems, consultants to Avista on the erosion inventory and assessment, showed a group including Avista’s Meghan Lunney, Becky Kramer from the Spokesman-Review and myself just how much the banks of this part of the St. Joe have eroded over the years, primarily due to the wave action caused by boats in high water. Bruce Gardipie, a member of the Kootenai, Salish and Confederated Tribes of Montana, who has lived on the Coeur d’Alene Reservation for 40 years, was our boat operator, and provided additional expertise.
I never even knew where the actual channel of the St. Joe ran, let alone that recreationists like myself could potentially contribute to its erosion. It was an eye-opener, and a good learning experience.
Now that the Spokane River FERC license has been issued, it’s great to see the work beginning, and it’s even better to see years of planning resulting in people working together to protect and improve the environment. This is just one of the many protection, mitigation and enhancement measures that we will implement in collaboration with the Tribe as part of our license and our ongoing commitment to protect natural resources associated with our hydroelectric projects.
Nov 10 , 2009 The Q’emiln Park boat launch ramp on the Spokane River in Post Falls, Idaho will be closed for the season beginning Friday, Nov. 13. The ramp, located upstream of Avista Utilities’ Post Falls Hydroelectric Development, is typically closed each year in mid-November due to weather conditions and dropping water levels.
The boat launch must remain closed for safety reasons whenever water is spilled through gates at the Post Falls Dam, which can be the case for much of the fall through spring. The ramp will re-open in the late spring or early summer, depending on the amount of inflows into Coeur d’Alene Lake
As a result of Avista’s annual drawdown of Coeur d’Alene Lake, Spokane River levels above the dam will be approximately three feet below summer elevation on Nov.13. Water levels may drop by as much as five additional feet by the end of January. These water levels are subject to change due to weather conditions.
Avista has a 24-hour telephone information line that provides notification of anticipated elevation changes on Coeur d’Alene Lake, Lake Spokane and the Spokane River during the subsequent 24-hour and one-week periods. In Idaho, call (208) 769-1357; in Washington call (509) 495-8043.

Avista will begin lowering the water level at Lake Coeur d’Alene and the Spokane River behind Post Falls Dam on Tuesday, September 8 in accordance with its new Federal Energy Regulatory Commission license.
Avista manages the lake level to prepare for spring runoff, to mitigate flooding in the winter and to optimize power production. The drawdown will take several months to complete.

I just got word that we’re going to have a planned outage next Tuesday, Sept. 1, for some customers along Lake Coeur d’Alene. Our crews are working on improvements to our Ogara substation and they need to shut off the juice for about four hours.
Approximately 760 Avista customers on the east side of Lake Coeur d’Alene from Carling Bay south to Ogara Bay, including the City of Harrison and customers on Hells Gulch Road will be impacted by the outage. About 575 Kootenai Electric Cooperative members on the southeast side of Lake Coeur d’Alene and in the Harrison area will also be impacted. The outage will begin at 3:30 a.m. and is expected to last until about 7:30 a.m.
This event is a good chance to talk about infrastructure upgrades, improved reliability projects and meeting customer demand. We always use those buzz words when talking about rates and why we file requests for increases. This work shows where some of those words are put to action. Customer demand in the area has increased and work on the sub will allow for increased demand.
So, if you live in this area, you’ve got a couple days to find a battery-power alarm for that early morning wake-up call. Personally, I opt for the cell phone alarm. It’s plenty loud and the phone holds a charge for a few days.
If you are impacted by this outage, drop us a line and let us know how it went.
