Irrigation districts announce water release dates

The City of Nampa will begin its irrigation season by filling the pressurized system on April 2. Full pressure is not to be expected until mid-April.

Nampa & Meridian Irrigation District, Pioneer Irrigation and Boise-Kuna District plan to release water into the canal systems on April 2, however, it could take up to two weeks before the water is available for pump operations due to charging and flushing the systems.

City of Nampa irrigation customers should have irrigation water at full pressure by mid-April after crews have tested lines, flushed the system and brought ditch pumps on line.

As crews find problems with water lines, they shut them down for repairs which can result in customers having water one day and not the next, so patience is requested.

If you notice a leak, please call 208-468-5860. This is a 24-hour a day phone number. Due to the volume of calls, if you get our voice mail please leave a message. We will call you back as soon as possible.

All Nampa residents are asked to check the programming of their sprinkler control box to assure they are not unknowingly over-watering. Those who need help setting a sprinkler control box should contact a lawn care professional. Residents are also strongly encouraged to install their own shut off valve to control sprinkler lines and not to operate the city valve as this is for emergency use only.

New Nampa residents may not understand how an irrigation system works. The City of Nampa receives the majority of its irrigation water from canals and ditches supplied from mountain reservoirs like Arrow Rock, Lucky Peak and Anderson Ranch. Pumps draw water from the canals and ditches to provide pressurized service to the city’s customers. The length of the irrigation season is dependent on water in the reservoirs and canals.
