    Your Irrigation District: A Vital Part of the History of Canyon and Ada Counties

    Nampa & Meridian Irrigation District was formed in 1904 to bring water to Idaho farmers developing the lands of Canyon and Ada Counties by creating a system of canals and storage reservoirs.  Some of our water rights from the Boise River date from the late 1800’s.  We also have storage rights that date from the early to mid 1900’s in the Arrowrock and Anderson Reservoirs.  For over a century, Nampa & Meridian Irrigation District has played a crucial role in the economy of the Treasure Valley.

     

    About Your Irrigation District Assessment

    Under Idaho law, the District assesses land inside its boundaries to help pay for the operation and maintenance of the District’s water storage, drainage, and distribution system.  Assessments for each tract of land are based upon the land’s water rights.  Idaho law specifies that the assessment becomes a legal obligation of the land and, therefore, a responsibility of the landowner.


    The District also receives income from the hydroelectric plant at Lucky Peak Reservoir.  Those funds are used to reduce the annual costs to you.
