Everist Reservoir: Flood Hazard Evaluation Fort Lupton, Colorado
The L.G. Everist Fort Lupton gravel mine is adjacent to the South Platte River north of Fort Lupton, Colorado.
As the gravel mining progresses, the pits are being reclaimed as a series of six slurry wall lined reservoirs.
The total reservoir storage in the complex will be approximately 6,300 acre-feet.
Deere & Ault Consultants, Inc. developed a HEC-RAS hydraulic model of the South Platte River in the
vicinity of this project to determine the impact of temporary stockpiles on the floodplain. This modeling was
conducted as technical documentation in support of a previously prepared Flood Hazard Development Permit. The
modeling demonstrated that the temporary stockpiles did not adversely impact the base flood elevation of adjacent
properties.
