The Boise River is flowing at nearly 8,000 CFS per second, and it's measured at just under 11 feet Friday.

For now, a flood warning issued by the National Weather Service will remain in effect until the river drops below 7000 CFS.

Water has already overflowed the banks at many points and could get even worse, especially in the Eagle area. 

Emergency Management Officials have identified a problem with a privately owned gravel pit that sits next to the Boise River, upstream from the City of Eagle's floodplain area.

Engineers are now saying they expect the ground around the pit to fail, and when it does, it is likely that residential roads and even portions of eagle road will be covered with water and not passable.

Eagle Fire explained that normally roughly 70% of the water is diverted to the North Channel of the Boise River and only 30% to the South Channel. When the land fails, even more water will be pushed through the South Channel, which is already at full capacity, flooding the area.

While they said there is no way to predict the exact course of events, worse case scenario, it could affect thousands of homes.

They said they are not trying to scare people, they just want everyone to be ready.

An email was sent out the residents in the following affected subdivisions from the City of Eagle:


Duck Alley

Island Woods

Laguna Pointe


Mace River

River's End


Two Rivers


In the email, they asked residents the following:

Not to cross flowing water.

Remove chemicals, fertilizers, gas and fuel cans, as well as propane tanks from low-level areas.

Move motor vehicles, campers, motor homes, and boats.

Prepare a "go bag" containing water, clothing, and other essentials for everyone in the home.
