In response to issues surrounding interstate compacts and intra-basin concerns, the State Engineer promulgated rules regarding the measurement of ground water for the following river basins: the Republican River Basin (within an eastern portion of Division 1, the Arkansas River Basin (Division 2) and the Rio Grande River Basin (Division 3). Rules governing the measurement of tributary ground water diversions in the South Platte River Basin (Division 1) have been approved by the Division 1 Water Court (2011CW292).
These rules require certain wells to have a measurement device, such as a totalizing flow meter (TFM) or, under specific qualifications, a power conversion coefficient value (PCC), installed and verified by a certified well tester.
The types of wells that are likely to be subject to these measurement rules have a pumping rate higher than 50 gallons per minute (gpm), and / or are used for, including but not limited to:
|• Crop Irrigation
• Feedlot or Confined Livestock Operations
• Municipal purposes
• Commercial purposes
| • Industrial purposes |
• Augmentation purposes
• Oil and Gas production
Those wells which may be exempt pump less than 50 gpm and are used for residential purposes
in one to three single family dwellings, home lawn and garden irrigation of a maximum of one acre, certain livestock or domestic animal watering, or some limited commercial purposes.
Please refer to the basin page in the menu at your left for more specifics on each basin’s measurement rules.
Finally, in addition to the above referenced measurement rules, Designated Ground Water, outside the Republican River Basin, may also be subject to the Ground Water Commission’s rules and policies governing the measurement of water. Additional information on the Ground Water Commission’s Rules may be found on the Ground Water Commission
page and specific requirements for a well may be referenced in the well permit file. Please consult the well permit file for additional details and if you have any questions, please contact the Division of Water Resources
