Plans for Dry Creek Lake move forward November 8, 2017, 3:35 pmThe debris basin, which was originally built in 1962 as a high hazard dam, had been earmarked for upgrading by the conservancy district to bring the dam and debris basin up to current federal standards and extend the life of the structure. Lehi City officials approached conservancy district officials about increasing the scope of the project to allow the lake to serve as additional year-round pressurized irrigation water storage capacity for Lehi City and provide recreational activities such as fishing, swimming and non-motorized boating. The conservancy district has received a USDA grant for 65 percent of the upgrading project. Dry Creek Debris Basin is eligible for rehabilitation funding due to its high hazard class and outdated infrastructure. Lehi City would cover 35 percent of the construction and all of the amenity costs - a total of about $3 million. The planning level cost estimate (including environmental, design, and construction) for the project (not including the recreational amenities) is $7,604,000. The project will raise the dam by 4 feet, raise the auxiliary spillway 5 feet, replace the principal and auxiliary spillways, add downstream improvements, sediment excavation and additional measures to maintain a constant pool of water in the basin. According to a draft design for the lake by RB&G Engineering, the lake will be 700 feet wide at its widest point near the dam, 2,000 feet long and 26 feet deep at its deepest point at the base of the dam. The water level will be controlled via a Lehi City outlet pipeline combined with outflow from the spillway located at the dam. Lehi City is in the initial stage of designing the surrounding amenities (parking lots, pavilions, beach area, etc.) and pressurized irrigation pipeline which will extend south and west of the what they are calling Dry Creek Lake. Final cost estimates will not be available until later this year. Lehi City Engineer Lorin Powell presented the plan to Highland Mayor Mark Thompson and city council members on September 5 and informed them that conservancy district officials were interested in seeing the entire lake annexed into Lehi. Currently, the boundary between the two cities sits in the middle of the lake. At that meeting, Highland Councilman Brian Braithwaite expressed support for the project but said he wants to ensure that several Highland City neighborhoods directly adjacent to the property are not negatively affected by the project. He wanted to be sure that Highland City still had some visibility in the project. He expressed concern that if the boundary between the cities was changed there would be no one to represent those residents.
