June 30, 2008 <br />Appendix B <br />Descriptions of Potential Flow -Based Protection Ideas Prepared <br />by the Water Rights Subcommittee <br />Introduction <br />This document provides detailed descriptions of flow -based protection concepts being <br />considered by the Stakeholder Group for inclusion in a Wild and Scenic Management Plan <br />Alternative. Each description provides a discussion of the basic concept, a description of the <br />benefits in Colorado River Segments 4 through 7 (as described in the BLM Wild and Scenic <br />Eligibility Report for the Glenwood Springs and Kremmling Field Offices), an assessment of <br />whether the concept can provide permanent flow protection, and a discussion of the pros and <br />cons for the concept. The descriptions are not set in any order of priority in the sections below. <br />1. DELIVERY OF WATER TO A DOWNSTREAM DEMAND <br />I. Basic Concept <br />Water that is made available for streamflow protection would be released into the <br />Colorado River or its tributaries upstream of the protected stream segments. That water <br />would be delivered to a party within or downstream of the protected segments who <br />contracts for the use of the water. Potential sources of water include: storage releases <br />from upstream reservoirs, such as Granby, Williams Fork, Green Mountain, or Wolford <br />Mountain Reservoirs; changes of existing water rights, such as the Peabody Ditch in <br />Summit County; and bypasses from trans - mountain diversion facilities. Examples of <br />potential downstream delivery points could include municipal or agricultural users in the <br />Grand Valley, municipal or energy industry users in Garfield County, on- channel <br />hydroelectric projects, or a mainstream RICD. This approach could also be used to <br />deliver water to an ISF right under an agreement with the CWCB. <br />II. Benefit to Stream Segments <br />The amount of water that could realistically be developed and delivered to a downstream <br />demand needs to be assessed. <br />III. Permanent Flow Protection <br />Permanency of flow protection will depend on the duration of agreements between the <br />source of supply and the ultimate water user. <br />
