A peek at Avista’s Bald Eagle Management Plan for the Spokane River Project
36 years ago, our nation’s bird and symbol of freedom was placed on the endangered species list. Today, the birds are rebounding again across the country and locally.
Avista’s Terrestrial Resource Specialist, David Armes, is in charge of implementing Avista’s Bald Eagle Management Plan – something we are required to do as part of our federal license to operate our Spokane River Project’s five hydroelectric facilities.
Our contribution to the protection of the Bald Eagle includes annual surveys and monitoring of Bald Eagle nests located near the Spokane River Project area. This includes Coeur d’Alene Lake and its three tributaries; the Coeur d’Alene, St. Joe and St. Maries Rivers as well as the Spokane River and Lake Spokane.
While conducting surveys we look to see if the nests are occupied, evaluate the success of the nests and observe the fledging period, a time when newborn Eagles are preparing to leave the nest.
The information we gather is shared with natural resource agencies, such as the Washington Department of Fish and Wildlife, the Idaho Department of Fish and Game and the U.S. Fish and Wildlife service. The information helps shape future efforts for protecting Bald Eagles in the area.
Avista is proud to support the conservation effort of our nation’s bird and will continue our legacy of environmental stewardship and reliability.

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 boater safety cables located just upstream of the Post Falls Dam. River flows have dropped sufficiently to allow all of the spill gates at the hydroelectric facility to be closed.
The City of Post Falls boat launch and swim beach at Q’emiln Park was opened to the public today. Typically this occurs sometime between Memorial Day and the July 4 holiday, and on average about June 22.
This year, several factors delayed the closure of the spill gates at Post Falls Dam. The spring runoff season extended well into the month of July, due to a larger than average snowpack and rainfall in June that amounted to more than twice the normal amounts.
Avista’s project to replace the lifting hoists and old timber intake gates at its Post Falls Dam with modern lifting hoists and new steel gates delayed the spill gate closure an additional week. During the work, at least two generator units must be taken out of service, which reduces the amount of water that can pass through the power house at any one time. This means the total river flow had to be lower than normal before the spill gates could be completely closed and the Q’emiln Park boat launch could be opened.
Visitors to Falls Park will see equipment and temporary work structures in and around the river, including cranes, barges, trucks and contractors throughout the project, which is expected to be completed by November. Some areas of the park may be temporarily fenced off, and detours or alternate viewpoints may be designated for park visitors. The public is requested to obey posted signs, stay out of the area of the river below the dam and keep clear of designated work areas.
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 and dam operations can cause rapid changes in water levels. Please exercise caution when using the waterways.
For current information on anticipated elevation changes on Coeur d’ Alene Lake, Lake Spokane, and the Spokane River, 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.

One of the original operators of Cabinet
Gorge Dam, 90-year old Clyde Meredith,
who retired in 1984, rode alongside
Cabinet's current Chief Operator.
Avista employees and the community of Clark Fork celebrated our Independence Day and commemorated Cabinet Gorge 60th anniversary at the annual Clark Fork, Idaho - Fourth of July celebration last week.
Several of Avista’s hydro operations and environmental resources employees and their families, a line truck, electric safety demonstration trailer and Bull Trout education trailer took part in the community’s annual Fourth of July parade.
One of the original operators of Cabinet Gorge, 90-year old Clyde Meredith, who retired in 1984, was also in the parade. He rode alongside Cabinet Gorge’s current Chief Operator, Don Wells in Clark Fork License Manager Tim Swant’s 1965 Pontiac LeMans.
Avista helped support the community celebrations and fireworks, and donated a trailer-mounted BBQ to the Clark Fork Booster Club so they have a means of fundraising for many years to come.
We’re proud to be a part of the community of Clark Fork for the past 60 years. Happy Birthday to America, and to Cabinet Gorge.

We’re replacing the lifting hoists and old timber intake gates with modern lifting hoists and new steel gates. The work is expected to update a system that is more than 100 years old in places, enhancing safety and increasing reliability and efficiency at the dam. We were also planning to refurbish the spill gates in the south channel of the river, but that project has been postponed until 2013.
The intake gate replacement project is scheduled for July-November 2012 while river flows are at summer levels. During the project, we’ll do our best to minimize the disruption to recreation and power generation as much as possible, but the work is important so we can continue to safely generate clean, reliable hydropower. The project will affect park users, boaters and dam operations.
Q’emiln Park Boat Launch: During the work, at least two generator units must be taken out of service, which reduces the amount of water that can pass through the powerhouse at any one time. This means the total river flow will need to be lower than normal before the spill gates can be closed and the Q’emiln Park boat launch can be opened. Depending on weather, this will likely take place sometime in mid-July.
Falls Park: Falls Park visitors will see equipment and temporary work structures in and around the river, including cranes, barges, trucks and contractors throughout the project duration. Some areas of the park may be temporarily fenced off, and detours or alternate viewpoints may be designated for park visitors. For your safety, please obey posted signs, stay out of the area of the river below the dam and keep clear of designated work areas.
Post Falls Dam Informational Meeting July 10
Avista will host an informational meeting to discuss the project and answer questions on July 10 from 5:30-7 p.m. at the Post Falls Police Department in Post Falls at 1717 E. Polston Ave. The meeting is open to the public. For more information, please call Mac Mikkelson at 509-495-8759. We'll be sure to keep you updated as the project reaches completion.

Will summer ever get here? That’s seems to be a common question heard around the Spokane area these days and at Avista too. As you make plans for the upcoming weekends and July 4 holiday, we want to keep you up to date on changing conditions in the Spokane River as well as educate you about a project we are working on at the Post Falls Dam.
We’ve started closing spill gates at our Post Falls Dam now that Coeur d’Alene Lake is back below the maximum summer level of 2,128 feet. However, heavy rainfall throughout the month of June has slowed our process, and we’ve had to make ongoing adjustments to accommodate river flows, which have increased rapidly on a number of occasions, as recently as Tuesday, June 26.
Closing spill gates causes the river level below the dam to decrease. With this in mind, the spill gates need to be closed gradually, so that fish below the dam are not stranded in pools of water. To achieve this we close spill gates at a rate that decreases the downstream river level no more than four inches per hour, which is required by our Federal Energy Regulatory Commission (FERC) license to operate our dams on the Spokane River.
As the river flows stabilize, we continue to close the remaining spill gates. As the spill gates are closed the elevation of the river above the dam increases, which provides additional recreational opportunities on the river. Once the final spill gate is closed, the Q’emiln Park boat launch in Post Falls can be opened for the summer season. Typically this occurs sometime between Memorial Day and mid-July. The median date for closing the gates is June 22. We don’t expect to close the final spill gate until after July 4 due to this year’s rainfall and extended high spring runoff season.
We’d like to remind you to always 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.
The best way to get the most current 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.

Avista’s summer work at Post Falls Dam
The dam needs ongoing maintenance and updates to keep it running safely and efficiently. This summer after the spring runoff season ends, Avista will be undertaking two projects to do that.
We’re planning to sandblast, repair and repaint the south channel spill gates, something that needs to be done every 30 to 40 years. We also plan to replace the lifting hoist and old timber intake gates that let water flow through the dam to the generator turbines at Post Falls Dam with new lifting hoists and steel gates.
Normally the generator turbines can pass about 5,400 cubic feet per second (cfs). Any additional water has to flow through the spill gates.
During the work, at least two generator units must be taken offline, which reduces the amount of water the power house can pass at any one time. This means the total river flow will need to be lower than normal before we can close all the spill gates and the Q’emiln Park boat launch can be opened.
Depending on weather, this will likely be about the second or third week of July.
During the project, we’ll do our best to minimize the disruption to recreation and power generation as much as possible, but the work is important so we can continue to safely generate clean, reliable hydropower. We'll be sure to keep you updated as the project reaches completion.

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 gray skies and damp days have certainly been a bummer over the last few weeks. Isn’t summer supposed to happen around June? But, as a signal to some light at the end of the tunnel, a huge rainbow spread across the Northwest yesterday. Avista’s Michael Williams happened to be at Riverfront Park last evening and snapped the image above.
The rainbow looks to be sticking out of our Upper Falls power house, which generates hydroelectricity for downtown Spokane. Clean, renewable and cheap hydropower is certainly a pot of gold at the end of the rainbow for our region.

Use caution as water levels continue to change
The North Channel of the Post Falls Dam.
Because of the recent heavy rainfall in the North Idaho mountains, Avista has been actively opening spill gates at our Post Falls Dam. Over the past several days, river flows and lake levels have risen steadily. The St. Joe and Coeur d’Alene rivers, which feed Coeur d’Alene Lake, have been rising for almost a week and continue to do so. Coeur d’Alene Lake reached summer elevation of 2,128 Wednesday, June 6 and continues to rise as flows into the lake exceed the amount that can flow out of the lake into the Spokane River.
Once Avista begins controlling the level of Lake Coeur d'Alene each spring, we are required to open the spill gates at Post Falls to prevent the lake from going above its summer elevation.
There is still above-average snowpack in the high mountains for this time of year, and the National Weather Service is predicting higher than normal precipitation and cooler temperatures for the month of June.
How does it all work?
You may wonder why river levels drop above Post Falls Dam when Avista opens the spill gates. In the summer, when all the spill gates are closed, the river is filled with water and acts more like a lake. Levels are held at a level very close to that of Coeur d’Alene Lake. But when we open the spill gates (some of which open all the way down to the river bed), the river flows naturally and the elevation of the water drops to river level. This is naturally much lower than it is when the gates are closed and the water is stacked up behind the dam - in fact, when all the gates are open, the elevation of the river above the dam is eight vertical feet lower than the summer level when the gates are closed.
We want to remind you to always 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 in a lake or river at risk for hypothermia.
Call Avista’s 24-hour telephone information line for information regarding anticipated elevation changes on Coeur d’ Alene Lake, Lake Spokane, and the Spokane River.

Spokane River and Clark Fork River work targets fish survival, habitat and doing the right thing
If you’ve ever dipped a fishing rod into any of our local lakes or rivers you’re already aware of the great natural resources we enjoy in the Northwest. Because Avista operates hydroelectric facilities on the Clark Fork and Spokane rivers, we’ve made a commitment to the environment as part of our daily operations throughout Montana, Idaho, Washington and Oregon.
Two great examples of Avista’s commitment to environmental stewardship are reducing invasive lake trout in Lake Pend Oreille and studying rainbow trout spawning on the Spokane River. These projects were featured in a 2010 “Safekeeping” segment of the Columbia Country television program which aired on Fox stations.
Clark Fork River
The Clark Fork Project segment features an ongoing collaborative project on Lake Pend Oreille to reduce the population of invasive lake trout. Lake Pend Oreille was once a world-class fishery for rainbow trout, bull trout and kokanee. In recent years, the lake has been taken over by lake trout (also called mackinaw), which do not coexist well with native bull trout, and which prey on kokanee, depleting the food sources for rainbow and bull trout. This project offers angler incentives and brings in commercial netters to “fish out” the invasive lake trout. Since this program’s inception more than 139,000 lake trout have been removed from the lake.
Avista helps fund the Lake Pend Oreille project through our Clark Fork Project license, which includes Noxon Rapids Dam in Montana and Cabinet Gorge Dam in northern Idaho.
The Spokane segment features a rainbow trout spawning study on the Spokane River, part of our 50-year operating license for the five hydroelectric developments that make up Avista’s Spokane River Project. The spawning study is part of a 10-year collaboration with Washington Department of Fish and Wildlife (WDFW) to better understand the relationship between river flow and the rainbow trout population and their spawning habitat from Monroe Street Dam downstream to Nine Mile Dam.
In each of the last two years, in partnership with WDFW, we’ve captured and tagged more than 800 rainbow trout in the river below the Monroe Street Dam downstream to the Nine Mile Reservoir. This part of the 10-year study is to understand how many trout are in the Spokane River and the habitat they use. We will capture and tag rainbow trout again this October.
A similar project has been in effect for several years in the Upper Spokane River, and we hope this project will help us better understand how managing river flows affects water levels in Lake Coeur d’Alene and habitat for rainbow trout downstream. By doing so, we hope to ultimately encourage growth of the rainbow trout population in the Spokane River.
Both of these projects show how Avista works with others to care for the natural resources affected by our projects. They are great examples of how we make our commitment to environment part of our daily operations throughout Montana, Idaho, Washington and Oregon.
