Jordan River Distribution Plan Issues Concerns from Lower Jordan River water users regarding changes on Utah Lake water rights Upper Jordan River direct flow distribution Concerns that Utah Lake water be used efficiently Conveyance losses Recent requests for environmental flows on the Jordan River Utah Lake + Jordan River + tributaries is a single system

Urbanization and Increased Surface Water Outflow Increased runoff -> fields to hardscape Increased municipal underground use Reduced depletion -> irrigation to municipal use Increased imports
Urbanization and Decreased Surface Water Outflow Development in non-tributary areas e.g. Cedar Valley Development of non-irrigated lands e.g. western SLV Increased underground use New surface water development Sewage effluent reuse

Managing Return Flows to River Pressurized System Regulating Ponds Turn Schedule Deliver to laterals based on actual acreage Better define conveyances losses
Conveyance Losses Conveyance losses in canals longer than a mile in length are to be determined as part of the general adjudication 1985 USGS Study looked at conveyance losses Conveyance losses consist of Seepage Evaporation Conveyance losses do not include water that returns to the river
