GEI Consultants Inc. will provide dam engineering services for the Long Hollow Dam and Reservoir project on the La Plata River near Durango, Colo.
GEI said it will design the dam, foundation, outlet works, and emergency spillway. The 125-foot high dam will be built on Long Hollow channel, about a half-mile upstream from the La Plata River.
According to GEI, the project will help the state meet its obligations under the La Plata River Compact by improving water flow to New Mexico. The reservoir will provide storage capacity and a reserve pool designated for release during low-flow river conditions to meet compact requirements with New Mexico, GEI said.
What’s more, the project will supply supplemental water to irrigated lands within the La Plata Water Conservancy District.
This is the second Colorado state compact project GEI is participating in. GEI is also working with the Republican River Conservancy District for design and construction services for a pipeline to improve administration of the Republican River Compact with Nebraska and Kansas.
