The Wyoming Water Development Commission
2015 Wyoming Irrigation Systems Report

The Wyoming Water Development Commission (WWDC) maintains a database of irrigation districts and companies in the State of Wyoming. A survey is conducted approximately every two years and the results are used to update the database. This survey provides important information for the agency's funding criteria. It aids in prioritizing the funds available for feasibility studies and project construction. In addition, this information allows irrigation districts and companies to compare operational issues, financial data, and general information with others around the state.

From the responses received, the WWDC divides the information into six sub-reports including a mailing list, conveyances, usage and storage, systems operations, and general information. This report also contains a list of entities that are in the database but have never responded to the survey. This survey can be accessed online or a copy can be requested from the WWDC.

A total of 176 Irrigation Districts and Canal Companies are listed in the WWDC database. Entity contact information was updated with assistance from active survey entities, Conservation Districts, Conservancy Districts, the Water User Organization Roster (4/22/2014), and the State of Wyoming Business Division Database (, 10/21/2014). After eliminating duplicate listings (due to name change or entity split), entities no longer in business, those requesting removal from the survey mailing, and those entities without contact information, the 2015 Irrigation Survey was distributed to 152 entities with a total of 75 (49%) entities responding. Of those 75 entities, an additional three (3) entities were either a duplication, out of business or wished to be removed from the mailing and were therefore excluded from the summary statistics. In comparison, the 2012 survey distributed 127 surveys and had a return of 65 (51%); the 2010 survey distributed 134 surveys and received 67 (50%) responses; the 2008 survey had 60 (32%) responses out of 189 surveys distributed.

The current survey was distributed by a variety of methods: ninety-five (95) entities were sent a hardcopy in the mail; forty-four (44) were sent emails to take the survey online, seven (7) requested the survey be sent by a combination of regular mail/online/email methods, four (4) surveys were completed by telephone, and two (2) were sent by email. In addition to the four (4) surveys completed by telephone, three (3) entities per telephone conversation required exclusion from summary statistics due to reasons previously mentioned, twenty-eight (28) surveys were returned by regular mail, thirty-seven (37) surveys were conducted online; and (3) three surveys were a combination of regular mail and the online survey. Combined with input from the 2008, 2010 and 2012 surveys, 108 out of 132 viable entities (82%) have responded to the survey within the past seven (7) years.

If you have any questions, comments or suggestions for future surveys, please contact Jon Wade of the Wyoming Water Development Commission, 6920 Yellowtail Rd, Cheyenne WY 82002 or call 307-777-7626.
