Utah Lake Drainage Basin Water Delivery System


The Utah Lake Drainage Basin Water Delivery System will complete the Central Utah Project. It is the last link in the complex system of dams, reservoirs, pipelines and tunnels that will bring water from eastern Utah’s Colorado River basin to populous Wasatch Front cities including Salt Lake City to the north and south to Utah County cities. The ULS System consists of buried pipelines extending from the terminus of the Diamond Fork System at the mouth of Diamond Fork Canyon in Utah County, down the Spanish Fork Canyon to the western side of the Wasatch Mountains. From there a series of pipelines will travel both north and south to deliver water to CUP customers. This system will deliver 101,900 acre-feet of CUP water for irrigation and municipal and industrial uses to Utah communities.

Spanish Fork Canyon Pipeline
The Spanish Fork Canyon Pipeline will connect to the existing Diamond Fork Canyon Pipeline at the Spanish Fork Flow Control Structure at the mouth of Diamond Fork Canyon. The pipeline will follow U.S Highway 6 down Spanish Fork Canyon to near its intersection with U.S. Highway 89. The pipe will be installed in the existing Highway 6 right-of-way. At the mouth of Spanish Fork Canyon, the pipeline will connect to three pipelines near the Highway 89 intersection: 1 )Mapleton-Springville Lateral, 2) Spanish Fork Canyon-Santaquin Pipeline, and 3) Spanish Fork Canyon-Provo Reservoir Canal Pipeline.

Mapleton-Springville Lateral Pipeline
The existing Mapleton-Springville Lateral, a Strawberry Valley Project facility, will be replaced with a pipeline throughout most of its length. This new pipeline will become a CUP, Bonneville Unit facility and will convey an average of 8,831 acre-feet annually of SVP water that has historically been delivered to the Mapleton and Springville Irrigation Districts through the existing ditch. The pipeline will start from a connection to the Spanish Fork Canyon Pipeline and extend north through the cities of Mapleton and Springville, Utah, a distance of 5.7 miles. Connections and turnouts in the pipeline, sized to match existing canal turnouts, will deliver water to Springville and Mapleton Irrigation District customers. In addition to SVP water deliveries, the new MSL pipeline will deliver CUP water to Utah Lake via Hobble Creek to assist with spawning and recovery of the endangered June sucker fish.

Spanish Fork Canyon - Santaquin Pipeline
The Spanish Fork Canyon – Santaquin Pipeline will connect to the Spanish Fork Canyon Pipeline at U.S. Highway 89 about 0.8 miles north of the Highway 6/Highway 89 junction and run along the adjacent Union Pacific Railroad right-of-way south to the city of Santaquin in south Utah County. CUP customers in southern Utah County will receive water from the pipeline through approximately eight planned pipeline turnouts.

Spanish Fork Canyon - Provo Reservoir Canal Pipeline
The Spanish Fork Canyon - Provo Reservoir Canal Pipeline will be constructed from the Spanish Fork Canyon Pipeline along U.S. Highway 89 north through the cities of Mapleton, Springville and Provo, Utah and discharge into the Provo Reservoir Canal, a Provo River Project feature. The pipeline will be constructed entirely within existing road rights-of-way. The pipeline will continue north to connect with the Jordan Aqueduct, an existing CUP facility. CUP water will be delivered to North Utah County and Salt Lake County customers via these combined facilities.

Santaquin - Mona Reservoir Pipeline
The Santaquin - Mona Reservoir (SMR) Pipeline will connect to the Spanish Fork - Santaquin Pipeline and continue along the Union Pacific Railroad alignment south to Mona Reservoir in Juab County. The SMR pipeline is planned primarily to provide water for a conservation pool in Mona Reservoir for the benefit of the endangered June sucker fish.
