Code of Colorado Regulations DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT Water Quality Control Commission REGULATION NO. 94 COLORADO’S MONITORING AND EVALUATION LIST 5 CCR 1002-94 [Editor’s Notes follow the text of the rules at the end of this CCR Document.] 94.1 Authority These regulations are promulgated pursuant to section 25-8-101 et seq C.R.S. as amended, and in particular, 25-8-202 (1) (a), (b), (i), (2) and (6); 25-8-203 and 25-8-204. 94.2 Purpose This regulation establishes Colorado’s Monitoring and Evaluation List. This list identifies water bodies where there is reason to suspect water quality problems, but there is also uncertainty regarding one or more factors, such as the representative nature of the data. Water bodies that are impaired, but it is unclear whether the cause of impairment is attributable to pollutants as opposed to pollution, are also placed on the Monitoring and Evaluation List. 94.3 Water Bodies Identified for Monitoring and Evaluation WBID Segment Description Portion Parameter COAR Arkansas River Basin .

  • A Classification of the Riparian Vegetation of the South Platte and Republican River Basins, Colorado 1998 Final Report
    A Classification of the Riparian Vegetation of the South Platte and Republican River Basins, Colorado 1998 Final Report by Gwen Kittel, Erika VanWie, and Mary Damm Colorado Natural Heritage Program Colorado State University College of Natural Resources 254 General Services Building Ft. Collins, Colorado 80523 June 1998 i ACKNOWLEDGMENTS Financial support for this study was provided by a grant from the Environmental Protection Agency (EPA) Region VIII, through the Colorado Department of Natural Resources, with in-kind services from the Colorado Natural Heritage Program. Additional funding was provided by the Bureau of Land Management's Colorado Office, the Bureau of Reclamation, and the Denver Water Board. We’d like to thank Karen Hamilton and Dale Vodenahl of the EPA, Doug Robotham of the Colorado Department of Natural Resources, Brenda Mitchell of the Bureau of Land Management, Will Tully of the Bureau of Reclamation, and Bob Curfasi and Don Kennedy of the Denver Water Board for their continued support. We'd also like to acknowledge all Riparian Task Force members for their support and technical assistance, and for making this project a success. The Riparian Task Force is a cooperative group of 14 agencies joined by a Memorandum of Understanding and dedicated to the development of a state wide riparian classification for Colorado (see Appendix E). Several individuals contributed to the success of this project. Lea Spears assisted in field data collection on in the South Platte study area, and entered data into the computer. Amy McMullen assisted in field data collection and edited early versions of this manuscript. Many people assisted with the logistics of the field season.
