<br />2, Support additional federal funding for the NRCS small watershed dam rehabilitation <br />program in Colorado, <br /> <br />3, Establish a program to facilitate the local sponsor matching funds for NRCS program <br />dollars to flow to Colorado; possibly a combination of grants and low interest loans, <br />These funds would go, in large part, to sponsors (dam owners) who have the <br />matching funds. <br /> <br />4, Support Colorado's presently successful state dam safety program with increased <br />funding levels. <br /> <br />3.0 PROGRAM ACCOMPLISHMENTS <br /> <br />3.1 General <br /> <br />The effectiveness of a program can be demonstrated by producing a positive result or <br />accomplishment. For fiscal year 2002-2003, the Dam Safety Program achieved a great number <br />of goals and objectives in the design review and inspection of dams, Although dam safety <br />incidents were reported this year, because of our program, these incidents resulted in reduced <br />consequences with no loss oflife or significant property damage. This is attributed to the <br />increased awareness of the dam owners to be responsible for their dams, including emergency <br />preparedness planning, and to the enforcement of the regulations, policies, and procedures by our <br />office, <br /> <br />As is typical, a number of dams experienced serious problems during the period. However, due <br />to the drought conditions that affected the entire state and the subsequent wet spring, many <br />reservoirs that had been dry or substantially lower than in past years resulted in the drying of <br />their associated embankments. The relatively wet spring caused many of these reservoirs to fill <br />quickly. This rapid filling lead to excessive seepage through dams that had experienced drying <br />and cracking of the embankment materials, This lead to an increase in the number of incidents <br />reported this year, However, due to the rapid response and quick thinking of our dam safety <br />engineers, none of the incidents lead to loss oflife or property damage, Incidents reported this <br />year include: <br /> <br />. Fisher Canyon Dam, a Class 3 structure, experienced rapid reservoir seepage losses of <br />approximately one vertical foot per day and significantly increased flows from a <br />previously documented spring approximately 500 feet from the dam. The reservoir was <br />drawn down and investigations were conducted to determine the cause of the seepage <br />losses. <br /> <br />. Warren Lake Dam, a Class 3 structure, experienced excessive seepage at the toe of the <br />dam. <br /> <br />. Anderson Dam, a Class 3 structure, experienced excessive seepage along outlet works <br />conduit. <br /> <br />7 <br />
