The goals of this project were to make improvements to the Jacoby Golf Course that would both mitigate flooding along an adjacent road, as well as provide water features and an irrigation reservoir for the golf course. The project was a cooperative effort between the University of Wyoming (UW) and the City of Laramie. UW contracted Trihydro to perform the work.

Trihydro was tasked with preparation of 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 as well as 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 reductions in irrigated area 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, and assisted in the bidding process along with permitting the ponds through the SEO.
