Monday, the Army Corps of Engineers is set to increase the flow of water out of Lucky Peak Reservoir to 9,500 cubic feet per second.

It's currently running around 8,900 CFS. When the river reaches 9,500 CFS, or 11.5 feet high, by sometime Tuesday, it'll be the 2nd highest flow rate ever recorded on the Boise River since recording instruments were installed at the Glenwood Bridge in the early 1980s.

Expect localized flooding in low lying areas. Homeowners near the river are encouraged to place sand bags around their homes to help stop the water from damaging property.

ADA County representatives have been concerned that flood water may capture a gravel pit in Eagle and change the course of river.

If that happens, the flooding could reach some Eagle homes. The scheduled increase in flows has some residents concerned, including Carrie Hastriter.

"As a mom, you just you think well what if, however we'll just hope for the best, of course our home does not lie in flood plain believe it or not and so when I called to see if we can even get flood insurance they said well you can't really get the full meal deal flood insurance but we can you give a supplemental policy that would of course cover some minor things," said Hastriter.

Though Hastriter hopes her home will be fine when engineers increase flows, she does worry about having to evacuate because of possible road closures from flooding.
