� <br />t <br />Johnson & Edwards Ditch Company (J&EDC): <br />The J&EDC diverts in common with the Prewitt Reservoir. The company plans to install <br />a radio/control unit to monitor flow at it's upper flume near the turnout from the Prewitt <br />inlet. At a future date, this unit could also control the turnout gate in the Prewitt Inlet <br />bank approximately a hundred feet upstream from the flume. This would probably only <br />be practical if a companion radio/control unit is installed to control the river diversion, <br />located approximately two miles upstream. This capability is not currently planned for ._ <br />the demonstration project. <br />Two recharge sites are currently in operation on the J&EDC system. A radio control unit <br />will be installed at a Parshall flume at the entrance to one site. The second recharge site <br />is located on a draw into which spill from the lower end of the J&EDC system runs. This <br />condition creates unique conditions which the radio/control equipment can greatly assist <br />in managing. <br />At various times, this draw may have natural seep flow passing through it or during <br />irrigation operations, spill from the J&EDC system may be flowing. For recharge <br />operations, any pre-existing seepage discharge must be maintained past a control <br />structure at the lower end of the draw as recharge flows are run into the site. During <br />irrigation season, recharge water may still be ponded in the draw, but canal spill must be <br />routed through and released through the control structure. Flow measuring structures <br />� <br />have been constructed at both the entra�ce and exit from this recharge site. <br />Radio/control units will be installed at both sites. The gate on the control structure at the <br />lower end of the draw will be automated to match a target release discharge. During <br />recharge fill, this target will be the pre-existing seepage flow rate. During irrigation spill, <br />the target release will be the measured incoming spill discharge transmitted wirelessly <br />from the inlet measurement structure. <br />Two groundwater irrigation wells serve lands that are under both the J&EDC and the <br />LP&BDC. Data collection and processing is complicated by the need to segregate <br />pumping data according to individual fields being watered. Both wells have McCrometer <br />propeller-type flow meters installed. Pulse output kits will be installed at these wells <br />along with a radio/control unit at each. The flow monitoring program code in the <br />radio/control units will be modified in order that the irrigator will be required to key in a <br />field identification indicator when turning on the ptunp. These units should ultimately be <br />configured to enable remote pump start-up and shut-down, but this is not included in the <br />current project scope. <br />A total of six field units and one remote (office) unit will be included in the J&EDC <br />portion of the demonstration project. <br />
