The CWCB appropriates water rights to preserve the natural environment of streams and lakes in the state. After receiving detailed recommendations for instream flow (ISF) water rights from state and federal agencies, conservation groups and members of the public, the CWCB reviews and processes the recommendations in accordance with the Board’s ISF Rules. The CWCB performs detailed hydrological analyses to ensure that all recommendations meet the statutory requirements for an ISF appropriation. The CWCB notifies and involves the public throughout the ISF appropriation process.
Each January, the CWCB holds a workshop to request recommendations for streams and lakes to be protected. The workshop is open to the public and notice is provided through this Website and the ISF Subscription Mailing List. Any person or entity may submit recommendations. All recommendations are processed in accordance with the ISF Rules and statutes.
Proposed and Contested Appropriations
Technical information for current recommendations is presented to the Board in January each year and provides the basis for the CWCB’s intent to appropriate for each stream. When an ISF appropriation is uncontested, the CWCB files an application in Water Court to adjudicate the ISF water right. If an ISF appropriation is contested, the CWCB follows the procedures in ISF Rule 5, which include holding a hearing on the ISF appropriation prior to taking final action on it. For more information about any recommendation, please contact Rob Viehl.
