The Wyoming Water Development Commission
2003 Wyoming Irrigation Systems Report

During the Fall and Winter of 2003, the Wyoming Water Development Commission (WWDC) conducted a survey of all known irrigation districts and canal companies in the State of Wyoming. The response to this survey was much improved from the previous 2001 Irrigation Survey. The WWDC is grateful for the cooperation of all the entities that participated in this survey.

The results of this survey have been summarized in the following reports. The irrigation districts and/or the canal companies provided all information included in these reports. Data was checked and verified only if there was a conflict or obvious discrepancy noted in the data entry process. Some districts and companies responded with incomplete information or indicated that some of the questions did not apply to their operation. Therefore, some data may not appear for certain entities. If more specific or more current data are required, users should contact the individual districts and companies.

The WWDC hopes these reports are beneficial to Wyoming irrigation districts, canal companies, agencies, and water users. If the information is not correct for your entity, please send correction to the WWDC as the database will be updated on a regular basis.

The 2003 Irrigation Systems Survey Report consists of five separate reports, each of which is explained in detail within the following Key to Irrigation Systems Survey Report. This key identifies and defines the individual fields in the reports. Codes used in various fields are explained at the beginning of the survey.

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