Irrigation water throughout the Mid-Columbia will begin to shut within two weeks, with the Kennewick Irrigation District taking the first steps to close irrigation flows to its 21,000 customers beginning Oct. 10.
The Columbia Irrigation District, which serves some areas in Kennewick and Finley, will start turning off water in its system Oct. 15.
Each irrigation district in the Mid-Columbia has its own schedule for terminating irrigation water service.
Badger Mountain Irrigation District will shut down water to its residential customers Oct. 18, but is allowing water until Oct. 28 for its tree-fruit growing customers, said District Manager Brad Anderson.
Never miss a local story.
"Due to unusual weather patterns this year, the apple crop will be harvested much later. Because of this, fruit growers will have little or no time following completion of harvest to make final application of irrigation water for post harvest purposes, which is necessary for the required moisture next spring for fruit trees prior to start of the 2012 irrigation season," he said.
KID's has set a schedule for shutting down water beginning Oct. 10.
w Oct. 10: Pressurized service areas in south Richland, including Hills West (PSA 73), The Orchards (PSA 134) and Willowbrook (PSA 141) will be the first to lose their water.
w Oct. 15: All pressurized service areas receiving water through the Columbia Irrigation District canal system will begin to dry up. They include Lampson Estates (PSA 5), Tri-City Heights No. 1 (PSA 6), Garber's Addition (PSA 82) and the Olmsted Addition (PSA 117).
w Oct. 17: KID's primary pumping station at Chandler on the Yakima River will shut down at 7 a.m., and the north and south Amon Pump will shut down by 12 p.m., affecting Panoramic Heights, PSA 163, Canyon Lakes, PSA 195 and Sage Crest.
PSAs off KID's main canal will see water stop in Snyder's Addition (PSA 42), Rolling Hills Estates (PSA 166), Country Meadows (PSA 171) and Canyon View (PSA 188).
w Oct. 18 will see KID's pump technicians turn off all other PSA pump stations.
While shutdown of the system will be completed Oct. 18, it will take several days for water to fully drain from all parts of the canal system.
KID officials advise caution when being near freshly drained canals, which can be hazardous due to slippery surfaces.
