This document combines the efforts of several individuals, agencies, and organizations toward a common objective: the identification, description, and preliminary evaluation of promising opportunities for protecting instream uses of water under existing laws in Colorado and Wyoming. This report is intended for the use of State and Federal planning and management personnel who need an overview of potential opportunities for preserving instream flows. It is not intended to replace or challenge the advice of agency counsel, nor is it written to provide legal advice. Instead, it is designed as a guide for the person trying to find his or her way among sometimes bewildering State statutes and administrative practices. This report is not, and should not be taken as, official policy or prediction of future actions by any agency. It is simply a summary of some potential opportunities for protecting instream uses.

Instream Flow Protection is a comprehensive overview of Western water use and the issues that surround it. The authors explain instream flow and its historical, political, and legal context; describe current instream flow laws and policies; and present methods of protecting instream flow. They provide numerous examples to illustrate their discussions, with case studies of major river systems including the Bitterroot, Clark's Fork, Colorado, Columbia, Mimbres, Mono Lake, Platte, Snake, and Wind. Policymakers, land and water managers at local, state, and federal levels, attorneys, students and researchers of water issues, and anyone concerned with instream flow protection will find the book enormously valuable.
