Gerry Knapp, Lower Arkansas Valley Water Conservancy District (LAVWCD), introduced himself to the committee and began his presentation on the Catlin Leasing-Fallowing Pilot Project. The project was approved by the Colorado Water Conservation Board (CWCB) in 2015, under House Bill 13-1248, to test leasing water as an alternative to permanent irrigated agriculture dry-up. The Catlin Canal is responsible for irrigating approximately 19,000 acres in the La Junta area. The project consists of six Catlin Canal farms, comprising 902 irrigated acres, that agreed to fallow up to 30 percent of the land each year for 10 years. This would guarantee up to 500 acre-feet of water per year to municipalities, such as Fowler, Fountain, and Security. The project uses a lease-fallow tool, developed by the State Engineer's Office, to calculate historical consumptive use. The tool standardizes the method for calculating historical consumptive use and return flows and helps to protect non-participants from potential injury. Mr. Knapp discussed the benefits and challenges of lease-fallowing. Benefits include providing farmers with a new cash crop, hedging against low crop prices, and providing opportunities for improvements and a reduction in buy-and-dry practices. Challenges for lease-fallowing include a lack of water delivery mechanisms for conserved water. He also discussed the lessons learned from the project, including recharge ponds being an effective tool to maintain return flows.
