Top 6 Things You Should Know

  1. The Terry Ranch project would add 1.2 million acre-feet of water to the city’s vast, existing water portfolio. Terry Ranch is an aquifer storage and recovery project, in which an underground pocket of water has been isolated in the rock for thousands of years. While new to Greeley, aquifer storage and recovery is common in the West.  Click here to read the facts about Terry Ranch aquifer storage. 
  2. The City has conducted extensive studies on this new water source. View an online story map to see those results. Go to our Test Results and Transparency page to find a list of all downloadable reports.
  3. Greeley will continue to rely upon its robust surface water supplies and recent upgrades to its Bellvue and Boyd water treatment plants. The Terry Ranch project would be developed over time as a back-up drought supply and long-term water storage asset in wet years. Click here to read an Overview of Terry Ranch and how it would work.
  4. Terry Ranch water contains uranium – like all of the city’s water sources – and the city already has proven it can clean the water to the high standards citizens have come to expect. Click here to read water quality data and testing results.
  5. The federal government required the city to look for alternatives to enlarging Milton Seaman Reservoir. Terry Ranch emerged as the most environmentally friendly alternative among hundreds of water storage options. Click here to read the history and background. 
  6. Because of its long-term status, Terry Ranch can be developed in stages over long periods of time, helping keep Greeley water rates low. Read about the Terry Ranch finances and purchase agreement here.
