The Colorado Water Conservation Board ("CWCB"), 1313 Sherman Street, Suite 718, Denver, Colorado 80203. Please direct communications regarding this notice to Robert Viehl, Chief of the Stream and Lake Protection Section rob.viehl@state.co.us: RECOMMENDATIONS FOR WATER RIGHTS TO PRESERVE THE NATURAL ENVIRONMENT TO A REASONABLE DEGREE, IN LARIMER COUNTY, COLORADO. The CWCB is the state water planning agency which, among other duties, is tasked with appropriating, acquiring and protecting instream flow (ISF) water rights to preserve and improve the natural environment to a reasonable degree for streams and lakes in the state. The CWCB is the only entity in the state that is authorized to appropriate ISF water rights. These water rights are held on behalf of the people of Colorado for the preservation of the water dependent natural environment. ISF water rights work within Colorado's water law system, and are junior to any existing rights and practices at the time of appropriation of the ISF. According to section 37-92-102 (3) (b), C.R.S. "Any such appropriation shall be subject to the present uses or exchanges of water being made by other water users pursuant to appropriation or practices in existence on the date of such appropriation, whether or not previously confirmed by court order or decree." For more information on whether this provision applies to specific undecreed uses of water in or above the proposed instream flow segments, and potential recognition of such uses in the CWCB's water court decree, or any other questions please contact Rob Viehl. CWCB staff and entities that recommended streams for ISF water rights are in the process of gathering scientific data on the subject streams to finalize the recommendations and specific flow rates. Flow rates will be based on the minimum flow rate necessary to protect the natural environment and typically vary seasonally depending on the needs of the species. The CWCB board may consider recommendations at either the normally scheduled January or March board meetings. If approved by the CWCB, these water rights will have an appropriation date no earlier than 2026. More information regarding the ISF Recommendations is available online at: https://cwcb.colorado.gov/2026-isf-recommendations. There is currently 1 recommended ISF stream segment in Larimer County that may be appropriated in 2026 on East Fork Roaring Creek. The East Fork Roaring Creek recommendation starts at its headwaters and terminates 3.49 miles downstream at the confluence with Roaring Creek. December 19 2025 LCOL0423565
