l <br />N-1 <br />I <br />I� <br />included in this report in the interest of supporting the design process. For a full <br />hydrological study please refer to the City of Durango Boating Park Hydrology Study, by <br />Gary Thompson of W.W. Wheeler and Associates. <br />Visual inspection and discussions with the City's Public Works Director (3) suggest that the <br />Animas River, within this reach, can be characterized as sandy cobble and boulders <br />deposited on bedrock. The shale bedrock is visibly apparent during lower flows. <br />Smelter Boating Park <br />The Smelter Boating Park, as noted, has a significant reputation among whitewater <br />enthusiasts. The site has been improved 6 times over the last 16 years. Many of these <br />improvements remain today and are certainly the reason Durango has been able to host the <br />quantity and caliber of whitewater competition that it historically has attracted. <br />The Smelter Boating Park encompasses a reach of the Animas River from just upstream of <br />the City's Municipal Waste Water Treatment Plant to an area just upstream of the City's <br />Chamber of Commerce. The right (West) bank of the Animas River in the upper part of <br />this reach is a site that has been a brownfield site in the past. The site has been cleaned and <br />capped. The upper reach of this bank has several areas that suffer from bank erosion. In <br />the past, erosion at this site has occasionally led to noted safety hazards to in- stream boaters. <br />The current configuration of this region has not been cited as a safety risk. The lower half <br />of the right bank is stable and high through the mid- section with some spreading in the <br />lower part of the reach. <br />The left (East) bank is made up of the Santa Rita Park itself. This bank has been repeatedly <br />reinforced and can be characterized as largely well armored. Improvements in the channel <br />5 <br />
