Duchesne Tunnel System

The Duchesne Tunnel is in a state of readiness to carry the high spring runoff flows.  The water control gates, the water flow rate sensors and other equipment are inspected to ensure they will function properly.  Some if this inspection and preparation work can actually be done remotely over the SCADA system.  Some of the other work requires Association employees to use snowmobiles or a snow cat to travel to the tunnel inlet and outlet, as well as to the Broadhead Diversion.

Weber-Provo System

The Weber-Provo Canal has been delivering water from the Weber River to the Provo River  throughout the winter under an ice cap that runs the full length of the canal.  As spring comes, the ice cap begins to break up.  This activity is monitored by Association staff to ensure that the ice does not form an ice jam and damage equipment.  Additionally, a special weir for measuring the lower winter flows at the Francis Gage is removed in anticipation of the high spring runoff flows.

 Deer Creek Dam and Reservoir

With the winter annual maintenance completed, the Deer Creek Reservoir spillway gates and operating equipment are checked one final time before the runoff begins in earnest.  The reservoir is nearly full this year, so there is a likelihood that the gates will need to be operated and that a controlled spill of the reservoir will take place.

Deer Creek Power Plant

Annual winter maintenance has been performed on the Deer Creek Power Plant, and  the generator controls and tube valves must be given one final check before runoff season.  The tailrace level control gates are inspected and tested as required.  This past winter, some modifications to the emergency power system for the power plant were completed.

Provo Reservoir Canal

The PRC requires a lot of preparatory work before the irrigation season begins in April.  The canal is inspected, trash is removed, and the concrete-lined sections of the canal are cleaned and any cracks are repaired.  The weeds are burnt off of the canal banks,the bottom of the canal is graded with a bulldozer and debris that may remain in the siphons is removed.  Equipment maintained in the shop during the winter is also re-installed during this time.

Jordan Narrows Facilities

The Jordan Narrows turbine-pump is reassembled and tested to ensure all parts are ready to operate.  The machinery  and buildings are cleaned and painted as required.  The siphon and penstock pipelines are inspected to ensure they are ready for the irrigation season.
