# Colorado HB 20-1157 (2020A) — Loaned Water For Instream Flows To Improve Environment

Under current law, the Colorado water conservation board (board), subject to procedural requirements established to prevent injury to water rights and decreed conditional water rights, may use loaned water for instream flows if the loaned water is used for preserving the natural environment of a stream reach that is subject to a decreed instream flow water right held by the board. The act expands the number of years within a 10-year period that a renewable loan may be exercised from 3 years to 5 years, but for no more than 3 consecutive years, and allows a loan to be renewed for up to 2 additional 10-year periods. The act limits the duration that an expedited loan may be exercised for up to one year, and prohibits an applicant from seeking additional expedited loans regarding a water right following an approved expedited loan of that water right.
