The Annual Irrigation Season

CID begins filling and flushing the canal system on or around March 20th, CID tries to have all gravity and pressurized systems operating by April 15th. CID recommends that all Patrons wait at least seven days after the canal begins filling to start using water as this gives us the chance to get the water cleaned and the system full. 

CID shuts down the Canal system down on or before October 15th every year. The district starts to winterize our systems immediately after. Patrons should shut their service valves immediately after to ensure their private system does not get filled with water during the district winterization.
