Lake level held down for maintenance on dam

The boat launch at Crescent Bay on Lake Roosevelt is currently high and dry, but Spring Canyon and up to 11 of 22 launches in the Lake Roosevelt National Recreation Area still reach the water. Spring Canyon, the lowest reaching launch, goes down to elevation 1,222.
The boat launch at Crescent Bay on Lake Roosevelt is currently high and dry, but Spring Canyon and up to 11 of 22 launches in the Lake Roosevelt National Recreation Area still reach the water. Spring Canyon, the lowest reaching launch, goes down to elevation 1,222.

Lake Roosevelt is being held at a level about 47 feet below the full mark while maintnenace is completed on the drum gates that hold the water back when the lake is full.

The Bureau of Reclamation, which operates Grand Coulee Dam, reports the lake will likely remain below 1,255 feet above sea level until May 10.

The water forecast for the Columbia River drainage above Grand Coulee Dam, from April to August this year, is estimated to 82.5 percent of normal, so the maximum level allowed for flood control right now would actually be 1,283.3 feet, less than 7 feet below spilling over.

But such flood control elevations are the maximum elevations allowed to ensure enough room in the lake for the spring runoff. Actual elevations may be lower “based on power demand, unforeseen power emergencies, changes in weather events, maintenance on the dam, etc,” the bureau explains on its website.

What a view!

Here’s another fine use of Instagram: highlighting the great hikes the Grand Coulee Dam area offers. This shot is of a very happy dog on top of Steamboat Rock, out in the midst of Banks Lake at the Steamboat Rock State Park. It’s a hunk of earth that didn’t wash away in the series of catastrophic floods that carved the Grand Coulee at the end the last ice age.

So standing atop the rock, about 800 feet above the floor of the Grand Coulee, you can imagine the torrents that flowed through the area thousands of years ago, leaving this dramatic landscape.

The dog may not get that, but he certainly enjoys it anyway.

Lake Roosevelt level is dropping

The level of Lake Roosevelt has already dropped to to a level not predicted until March, in a forecast put out in mid-January, 2015.

On Friday, Jan. 30, the lake surface was at about 1,276 feet above sea level, which will put out of reach several boat launches on the lake, but certainly not all. (See the list below).
The deepest access is offered at the Spring Canyon launch near Grand Coulee.

The U.S. Bureau of Reclamation, which operates Grand Coulee Dam, which controls the lake, had published an estimate of the lake level drop this year showing a flood control schedule that would have still held the level at full pool until the end of February and eventually dropping to about 1,243 in April, not as far down as in 2014. But factors including weather and power demand can be hard to predict.

People are amazed, and here’s a video to show why

People are constantly amazed by the size of the dam and the achievement of building it.

Visitors using Instagram are always posting how amazed they are when they see Grand Coulee Dam.

“It amazes me how humans built this large, amazing structure more than 80 years ago!” wrote @lishlo this morning in a public post.

The Bureau of Reclamation has produced a top quality documentary on the building of Grand Coulee Dam to show you the amazing story behind the immense effort, the big thinking, innovation and, yes, even politics it took. If you want to visit it, you’ll appreciate it even more if you understand the whole story, so we’ll post the video here, which you can also watch on a big screen in comfortable seats at the Visitor Center when you get here.
