Stormwater Control System and Irrigation Reservoir Design

Trihydro designed a stormwater control system and irrigation reservoir for the Jacoby Golf Course in Wyoming to mitigate flooding and create new water features. The team leveraged its experience in hydrologic and hydraulic modeling to achieve optimal design functionality while enhancing the golf course’s playability.

The project’s goals were to improve the Jacoby Golf Course, mitigate flooding along an adjacent road, and provide water features and an irrigation reservoir. It was a cooperative effort between the University of Wyoming (UW) and the City of Laramie.

Trihydro was tasked with preparing a stormwater control system and irrigation reservoir design for the Jacoby Golf Course. Trihydro built a hydrologic and hydraulic model of the golf course and upstream basin and used it to size a series of six interconnected detention and retention ponds. Trihydro worked with UW and golf course staff to determine the location and shape of the ponds to enhance the playability of the golf course. The lined irrigation reservoir was sized to irrigate the golf course and the UW recreational fields along 30th Street. A wind-powered pump and recirculation system was designed to provide circulation between the ponds and maintain water quality in the ponds.

As part of the project, Trihydro worked with the Wyoming State Engineer’s Office (SEO) and UW to determine sources of depletion credits under the North Platte River Recovery Act. A total of 10 acre-feet of depletion credit was achieved for UW by accounting for reduced irrigated areas and evaporative losses. A portion of the credit was used to mitigate the evaporative losses from the new ponds, and the remainder was banked for future UW projects. Trihydro prepared the design and construction documents, assisted in bidding, and permitted the ponds through the SEO.
