Arnold Irrigation District

Public Scoping Comment Period Ended May 15 for Proposed Infrastructure Modernization Project

Public comments were accepted from April 3, 2019 through May 15, 2019 related to the proposed Arnold Irrigation District Infrastructure Modernization Project. 

Questions, comments, and other information received during the scoping process will be considered through the development of a Draft Watershed Plan - Environmental Assessment for the proposed project. The Draft Watershed Plan - Environmental Assessment will fully identify and evaluate the project, the resources potentially affected by the project, and the effects of the project on those resources. Once the Draft Watershed Plan is complete, Arnold Irrigation District and the Natural Resources Conservation Service (NRCS) will release it for public comment and a second public meeting will be held to solicit questions and comments.

This page includes a fact sheet, map, and presentation from the April 17, 2019 public scoping meeting, and a preliminary report, which gives an overview of the District's infrastructure. 

On April 3, 2019, NRCS announced a public scoping meeting to consider improvements to aging irrigation infrastructure in Arnold Irrigation District, located in Deschutes County on the south side of Bend, Oregon. A public meeting was held April 17, 2019 from 6:30 p.m. to 7:30 p.m. at the Elk Meadow Elementary Gymnasium, located at 60880 Brookswood Blvd in Bend, Oregon.

Improvements under consideration may be partially funded through the Watershed Protection and Flood Prevention Act of 1954 (PL 83-566) and would address water conservation, enhancement of aquatic species habitat, and public safety risks while supporting existing agricultural land use.

The project is sponsored by the Deschutes Basin Board of Control and Arnold Irrigation District, with funding and technical support from the Energy Trust of Oregon, NRCS, and Farmers Conservation Alliance. NRCS is the lead federal agency for the proposed project. Farmers Conservation Alliance is a 501(c)(3) non-profit organization which, as a federal contractor, is assisting NRCS and the sponsors in the Watershed Plan - Environmental Assessment process. 

Arnold Irrigation District and project partners propose to modernize aging infrastructure to conserve water, reduce energy use, improve operational efficiencies, and enhance fish and wildlife habitat in the Deschutes River.  

Converting open-ditch irrigation canals into underground, closed-pipe systems could reduce seepage water losses by up to 14,607 acre-feet, a rate of up to 45.1 cubic feet per second, over the entire irrigation season.
