It is not enough for Dubya to ruin fishing in Idaho, Oregon, California and Washington, now he is going to ruin fishing in Montana.... When will the Madness end???
Fish in danger as reservoir drains
Posted Apr 29, 2004 - 05:08 PM
Pity the pike and perch of Peck. It looks like they won’t even get tumbleweeds for habitat this year.
Unrelenting drought has left Fort Peck Reservoir with just the last remaining bits of shallow-water spawning habitat and cover for young fish. It’s down to tumbleweeds that have blown into the lake.
But with the U.S. Army Corps of Engineers boosting outflows through Fort Peck Dam to 11,000 cubic feet per second this week, water levels will continue to drop, and even the tumbleweeds are expected to go high, dry and dusty in the weeks ahead.
According to the Corps, the higher flows are sure to last through May and could continue into the summer. The Corps said it is just following the plan it laid out for spring.
At Fort Peck, tumbleweeds were something of a last ray of hope for the lake’s northern pike and perch, according to Mike Ruggles, fisheries biologist for Montana Fish, Wildlife and Parks. These two fish species, in particular, need underwater structures on which to deposit their eggs.
On windy days, tumbleweeds by the hundreds are blown into the lake.
“It was nature’s way of bringing vegetation to the water, since the water seems to be staying away from plants,” Ruggles said. “The tumbleweeds have been very thick this year.
“The tumbleweeds were stacked up in the water near shore and in slack water areas and appeared to be nice perch spawning habitat. No doubt pike also spawned over some of the tumbleweeds blown in earlier,” he added.
“Unfortunately, water from the dam is going to be released at a much higher rate than the incoming water and the expected foot of water rise isn’t going to happen, which means some dried-up perch eggs and likely some dried-up pike eggs,” Ruggles said.
That’s bad news for just about all the fish species in Fort Peck.
“No way a lot of forage fish (bait fish) are going to successfully spawn this year,” said Bill Wiedenheft, FWP fisheries manager in Glasgow. “No cover habitat for forage fish or game fish in the shallows is going to ultimately have an effect on a lot of species - the forage fish, plus northern pike, walleyes, sauger.”
The lack of flooded vegetation, Wiedenheft said, “affects everything because your overall productivity in the lake goes down. It reduces the amount of nutrients in the lake. It affects your phytoplankton, plankton, everything. The vegetation breaks down and provides nutrients for the lake. Without the vegetation, it doesn’t have that. It’s tough on all the fish.”
From his Omaha District office, Corps spokesman Paul Johnston said boosting the outflows from the 6,000 cfs range in recent weeks to the 11,000 range Monday was just following the plan for the Missouri River mainstem reservoirs.
“Our plan early this year was to provide lake levels that were at least level (not diminished) in the big three reservoirs to help out their respective fish spawns,” he said. “The goal was to maintain Oahe (in South Dakota) level in April, which we’ve been able to do. We would maintain Sakakawea (in North Dakota) in May and then Fort Peck in June for the spawn of the forage fish there.
“We looked at the 78 percent of normal mountain snowpack and essentially no snow on the plains, and this is what we’ve had to do,” Johnston said.
The lake level on Fort Peck can be expected to drop another 1.5 feet to 2 feet by the end of May, he said. The lake level Monday was 2,205.3 feet of elevation.
“We won’t be going over 11,000 cfs (outflows through the dam) in May,” he said. “One of our generators has been out of service for two years. We’re limited to that much of a release. We’re sure not going to go above that and put water through the flood tunnels.”
Johnston said more numbers would be available as forecasts are projected later this week. He added that all of the numbers are predicated on shortening the navigation season on the lower Missouri River by at least 36 days this year.
“We’re just getting hammered by dry conditions from the Canadian border all the way down to the northern part of Kansas,” he said. “We’re doing what we can do.”
Just as Sen. Conrad Burns, R-Mont., blistered Corps Division Commander Brig. Gen. William T. Grisoli in a letter sent last Friday, Sen. Max Baucus, D-Mont., wrote an angry letter Monday.
“General Grisoli, I am tired of trying to work with the Corps on this issue, and to convince the Corps that Montana deserves to be treated fairly in the Corps’ management of the Missouri River,” Baucus wrote.
“I plan to introduce legislation as soon as possible in an effort to remedy this injustice. I will do everything in my power to finally get the Corps’ attention focused on Montana’s needs,” he added.
Rep. Denny Rehberg, R-Mont., is also working on legislation for the Corps’ management of Fort Peck and other Missouri River reservoirs.
