Pioneer Irrigation District is a non-profit irrigation district providing irrigation water to 34,000+ acres in the Canyon County and extreme Western Ada County area in Idaho. Established in 1901, we are proud to be a part of the Treasure Valley's rich agricultural history and are continually looking for the best ways to manage water needs now and for the future for both agriculture uses and the ever growing residential population in the Treasure Valley.

Statement Mistake:

Pioneer Irrigation District sent out what we thought were reminder notices to individuals that had not paid. Unfortunately, we had a glitch in our system and a past due notice was sent. The second half payments are not due until June 20, 2014. We apologize for any inconvenience that this may have caused you. Thank you for understanding!

Account Balance:

Irrigation District tax payments:

June 20th is the final date for approximately 1,350 patrons of
the Pioneer Irrigation District to pay their 2013 irrigation tax assessments, District officials announced last week.

The majority are individuals who paid the first half of their tax
bill in December and are not delinquent. However, the remainder
have paid either less than half of their 2013 taxes or nothing at all,
including some of whom have unpaid tax bills from previous years,
according to Pioneer officials.

Pioneer mailed tax assessments to approximately 5,700 patrons
last fall. Property owners had the option to pay their tax
assessment in full or in two parts, the first part by December 20th
and the remainder on June 20th.

“Idaho law requires irrigation districts to file with the County
Recorder’s Office a delinquency list of property owners who have
not paid their assessment on time,” said Eric Slayton, Pioneer Secretary.

“This action puts people on notice that a lien for unpaid
irrigation assessments has been placed on their property.”
State law then mandates that tax deed action be taken against
properties whose assessments have not been paid in three years.
People who have questions about their tax bill should contact
the Pioneer office at 459-3617 between 9:00 a.m. and 5:00 p.m.,
Monday through Friday. More information about Pioneer Irrigation
District is also available at its web site at www.pioneerirrigation
