Erosion possible as flows into Boise River increase

BOISE, Idaho (KBOI) - Flows are increasing sixfold into the Boise River this weekend. The additional water comes with a warning that riverbanks could erode.

The Bureau of Reclamation says increased flows will be noticeable with a bump from 300 to 1,800 cubic feet per second, which is "all part of normal springtime river operations and some routine maintenance on the New York Canal."

The agency also says the main concern is safety.

"The water's very cold coming off the bottom of the reservoir so they need to be careful," said Brian Sauer, Snake River Area Office Water Operations Manager. "We could be possibly seeing some banks eroding a little bit with the higher flows, so things have changed since last fall, last summer."

It's a warning for fishermen and others at the river's edge, but many are ready for the water to rise, including Carly Morisett of Boise and her two dogs.

"I know when it gets... flowing a little bit better and a little bit fuller, I take them for more walks along the river and maybe go up the river towards the dam a bit and maybe do some camping," Morisett said.

Sauer said by Monday morning, the river will be close to summertime levels at the peak of the irrigation season. The water will be higher than last July but "well below the Greenbelt," Sauer said.

"Reclamation expects an adequate water supply for irrigation and recreation activities through the season," according to a news release.
