ATTACHMENT A <br /> Detailed description of Long-Term Protective Measures <br /> A. CWCB Instream Flow for Baseflow <br /> Concept <br /> The CWCB can protect stream flows in and through a reach between two points on a <br /> stream by appropriating new ISF water rights. ISF water rights are held exclusively by <br /> the CWCB for minimum stream flows to preserve the natural environment to a <br /> reasonable degree, and are adjudicated and administered within the State's water right <br /> priority system. <br /> II. Benefit to Stream Segments <br /> For the segments containing a wild trout fishery, the ISF water rights would be based <br /> upon data collection and analysis geared toward the needs of the trout species present, <br /> and would establish a water right for those flows that would be administered in priority. <br /> The ISF water rights would meet the basic habitat needs of the wild trout fishery. <br /> III. Permanent Flow Protection <br /> An ISF water right provides permanent stream flow protection by virtue of its place in the <br /> priority system. While it cannot affect operation of existing senior decreed water rights, <br /> under state water law, it is entitled to stream conditions as they existed at the time of the <br /> ISF appropriation. ISF water rights have standing in Water Court to ensure that proposed <br /> plans for augmentation and changes to senior water rights do not alter stream conditions <br /> to the detriment of decreed ISF water rights. <br /> IV. Pros and Cons <br /> Pro <br /> • An ISF would provide permanent protection based on habitat needs. <br /> Con <br /> • An ISF would be a junior water right and CWCB may not be able to appropriate <br /> flows in the amounts needed to adequately protect the ORVs if those flows were <br /> determined to be more than the minimum required to preserve the natural <br /> environment to a reasonable degrees. <br /> Page 1 of 6 <br />
