On the river: Fish passage
November 9, 2007
GRAND JUNCTION, Colo. ” Endangered fish that, for nearly a century, have been kept from swimming up the Colorado River by an 8-foot high irrigation dam will soon get relief in the form of a $10 million fish passage.
U.S. Bureau of Reclamation officials said the Price-Stubb Dam, which was built in 1911, will have a notch cut into it by year’s end to allow construction of a 600-foot-long channel.
Doing so would allow the Colorado pikeminnow and razorback sucker to navigate several miles of river. The fishes’ critical habitat stretches from Lake Powell in Utah to Rifle.
About 190 concrete baffles along the passage, arranged in a series of triangular shapes, would slow the river current to allow the fish to swim upstream, said Mark Wernke of the agency’s Grand Junction office.
A whitewater park that was to built along with the passage was scrapped, but officials in Palisade were working on constructing a park down stream from the dam.
The Price-Stubb Dam, which is visible from Interstate 70, is about 15 miles east of Grand Junction.
