The Dalles Irrigation District performs monthly water quality testing during the pumping season to provide patrons with current water quality information. Since the irrigation water originates from the same source, the Columbia River, these results are representative of the water delivered across the district.

This is a reminder that District staff will begin filling reservoirs Monday morning, March 16, 2026.  

There may be a few tweaks still needed, so if you have any issues or need any support please let us know through our contact form. Thank you!

The Dalles Irrigation District will begin draining our system on the morning of 10/15/2025. 

TDID gets their power from a BPA substation on 10th St. This is what powers our whole district. BPA had a racoon get into the substation on the morning of 6/19/23. This caused damage to critical electrical equipment. Northern Wasco PUD, BPA and Wasco Electric all worked day and night to make the appropriate repairs. With their help we were able to have power restored and had water pumping by the next day. Thank you for all for your patience and we hope you have a great harvest.

Repairs have been made to our problem pump at pumping plant D. All lateral lines are now able to use 100% of their allowed GPM. Please stay within that limit to ensure everyone has the water they need. Thank you!
