This report provides the hydrologic and water rights information in support of the Town's application and <br />required by the CWCB to review the Town's application. Additional information in support of the <br />application is provided in a separate report by Recreational Engineering and Planning. <br />2.0 GENERAL INFORMATION <br />2.1 Boating Park Location <br />The general location of the Town or Carbondale Gateway Boating Park is shown on Figure 1. The <br />location is approximately 10 river miles upstream from the confluence with the Colorado River and <br />approximately 120 miles from the State line. The location of the specific structures is shown on Figure 2. <br />Five structures are located on the Roaring Fork upstream of the confluence Crystal River and the sixth <br />structure is located immediately downstream of the confluence with the Crystal. The total length of the <br />RICD reach, from structure 1 to structure 6 is 4,980 feet. The length from structure 1 to structure 5 is <br />1,500 feet. <br />2.2 Stream Gage Locations <br />For determining flows in the RICD reach two USGS stream gages on Roaring Fork River were utilized <br />(Figure 1). The Roaring Fork River at Glenwood Springs (Glenwood gage) has a record dating from the <br />present back to April 1906 and the Roaring Fork River at Emma (Emma gage) has been in service from <br />April 1998 to the present. Flow in the RICD reach was determined by extending the Emma gage record <br />by correlation with the Glenwood Gage and then adjusting the synthetic Emma gage record for major <br />irrigation depletions and accretions in the stream reach between the gage and the RICD. The procedure <br />is presented in greater detail in the Section 3.0, Water Availability. <br />2.3 RICD Claim <br />Based on generalized boating park structure designs prepared by Recreational Engineering and <br />Planning, projected boating park demand and water availability in the RICD reach seasonal water right <br />claims were made in Case No. 06CW77. The amount of Roaring Fork River stream flow claimed is <br />summarized in Table 1. <br />
