Title
Resolution Approving the Second Amendment to the 2025 Spot Water Lease Agreement Between the Town of Castle Rock and the Central Colorado Water Conservancy District [Chatfield Reservoir, Douglas County]
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water is seeking Town Council approval of a resolution (Attachment A) to amend the Spot Water Lease Agreement with Central Colorado Water Conservancy District (Central). On January 7, 2025 Town Council approved a spot water lease with Central for 400 acre-feet (AF). On September 2, 2025 Town Council approved a First Amendment to the spot water lease with Central for an additional 600 AF. Central has since exhausted the 1,000 AF and wishes to lease an additional 200 AF of surplus water stored in Chatfield Reservoir, for a total lease of 1,200 AF in 2025. This will allow Central to increase their storage supplies within Chatfield and have water upon which to make projections for their well pumping augmentation plans. While the Town currently owns 848 AF of storage in Chatfield, the Colorado Water Conservation Board (CWCB) allows for rental of the remaining permitted amount, for a total of 2,000 AF of storage. The Town currently has approximately 1,394 AF of water stored in the reservoir with additional reusable supplies coming in each day.
If Council approves the amendment to this lease, up to 200 AF of additional water may be released from the Town’s Chatfield Reservoir storage account as a “book-over” into Central’s Chatfield Reservoir storage account during 2025. This release may occur between November 18, 2025 and December 31, 2025. The Town will assess $110 per AF for the water. This is Castle Rock Water’s lease rate for agricultural uses out of Chatfield Reservoir. Payment will be required within 30 days from requested releases. The potential revenue for this lease amendment is up to $22,000. The agreement will terminate at the end of 2025.
Budget Impact
If Council approves the agreement amendment, Castle Rock Water would potentially receive up to $22,000 of additional revenue in 2025, for a total lease revenue of up to $132,000 in 2025. CRW has already received $110,000 from Central in 2025. The revenue will be deposited into the Water Resources Fund Capital Leases account 211-4375-393.70-00.
