<br />1.0 INTRODUCTION <br /> <br />1.1 Program Mission <br /> <br />The mission of the Dam Safety Program is to prevent property damage and the loss of life, while <br />protecting the loss of water supplies due to the failure of dams in Colorado through the effective <br />and efficient use of available resources, The program includes the enforcement of a <br />comprehensive set of regulations, policies, and procedures for the design, construction, <br />inspection, and maintenance of dams; the safe operation of reservoirs; and emergency <br />preparedness planning, In the event a dam is found to be unsafe, the risk of adverse <br />consequences due to failure of the dam is reduced by restricting the storage in the reservoir to a <br />safe level. The safe reservoir storage levels are determined by the results of engineering <br />analyses, the review and approval of engineered plans for the construction and repair of dams, <br />and regular safety evaluations of existing dams and reservoirs by licensed professional engineers. <br /> <br />The program is managed by the State Engineer in accordance with Title 37, Article 87 ofC.R.S, <br />(2002 Supp.) and the Livestock Water Tank Act, Title 35, Article 49 ofC.R.S, (2002 Supp,), as <br />amended. The "Rules and Regulations for Dam Safety and Dam Construction" and "Standard <br />Specifications for Livestock Water Tanks and Erosion Control Dams" establish the procedures <br />and requirements of the State Engineer in the implementation of these statutes. <br /> <br />1.2 Report Purpose <br /> <br />This report is submitted in compliance with Section 37-87-114.4 ofC.R.S. (2002 Supp,) <br />concerning the dam safety activities of the State Engineer and the Colorado Division of Water <br />Resources relating to Sections 37-87-105 to 37-87-114 of C.R.S. (2002 Supp.). <br /> <br />2.0 PROGRAM OVERVIEW <br /> <br />2.1 Goals and Objectives <br /> <br />The Dam Safety Program, although responsible for the approximately 2,900 dams within the <br />state, concentrates on "jurisdictional" dams and reservoirs as defined in Section 37-87-105 of <br />C.R,S, (2002 Supp.). Jurisdictional dams are dams that are greater than ten feet high as <br />measured at the spillway, impound a reservoir with twenty acres or more in surface area, or 100 <br />acre-feet or more in reservoir capacity at the high water line. Further, dams are classified as to <br />estimated downstream consequences as a result of failure of the dam in the absence of flooding <br />conditions as follows: <br /> <br />Classification <br />I <br />2 <br />3 <br /> <br />Descri tion <br />Loss of human life is ex ected in the event offailure of the dam, <br />Si nificant dama e is ex cted to occur, but no loss of human life is ex ected, <br />Loss of human life is not expected and damage to structures and public facilities is <br />not ex ected, <br />No loss of human life is expected and damage will occur only to the dam owner's <br />roe <br /> <br />4 <br /> <br /> <br />1 <br />
