Numeric modeling for the Proposed Nimbus Hatchery Weir Replacement Project

This is an on going project. As such, information presented here is primarily for communications with clients, it is a work in progress, and it is not complete or peer reviewed.

Due to lag-time effects, the water in the pool area is lower than actual. This is exacerbated by low meshing during this simulation that caused water to be "leaked" through the shoals as if it was a very porous media. These animations are for screening purposes only.

Discharge ramping up from 250 ft3/s to 8,600 ft3/s

Discharge ramping up from 8,700 ft3/s to 20,000 ft3/s
