Hydrology & Modeling
The Hydrology & Modeling section supports the planning and development activities of the Division of Water Resources by:
- Determining whether water supplies are sufficient
- Determining whether reservoirs and/or pipelines will assist in solving water shortages
- Supplying water budget data for statewide water planning
- Assisting the Construction & Design section with dam safety projects
The Division produces water models that analyze complex data to help make decisions for future water needs. The current models include:
- Bear River
- Great Salt Lake
- Jordan River
- Weber River
- Uinta River
- Virgin River
Cloud Seeding – The Division is responsible for the state’s cloud seeding program, which has been in operation since the early 1950s to help increase the state’s water supply. In Utah, we use ground-based propane generators to seed winter clouds to stimulate the precipitation process and generate snow. Placed along foothills and higher elevations, the release of silver iodide is timed so that the air currents will carry it high into the clouds.
The Cloud Seeding Act of 1973 requires cities and water entities to work with the state to administer the cloud seeding program. The state contributes matching funds up to $300,000 annually.
