<br />the temperature collection effort was realized in mid-May when data <br />from the recorder below Razorback Bar was used to identify the <br />beginning of razorback sucker spawning and crews were despatched for <br />spring sampling work. <br /> <br />B. Hydross Model Development <br /> <br />DWR participated in the development of a Colorado River Decision <br />Support System model being developed by the Colorado Water <br />Conservation Board by providing information on HYDROSS and reviewing <br />work in progress. Data developed for the Yampa River Feasibility <br />Study was incorporated into the HYDROSS model and the environmental <br />baseline for the Yampa River was updated to reflect newer data. <br /> <br />Yampa River Feasibility Study: DWR attended numerous Technical <br />Steering Committee meetings and provided information on the Yampa <br />River environmental baseline and reviewed reservoir operation <br />scenarios by Hydrosphere. Information on Yampa River diversion <br />depletions and return flows was also provided to Hydrosphere to <br />enable their model to duplicate the HYDROSS environmental baseline <br />as a benchmark. <br /> <br />C. Flooded Bottomlands. <br /> <br />DWR worked with Reclamation and Vernal CRFP office to identify flows <br />at areas such as Escalante wetland and Old Charly Wash that would <br />flood. Work entailed installing automatic cameras and water stage <br />recorders at inlets of these wetlands and monitoring daily flow and <br />stage at each location, The information from this work was <br />presented to the Flaming Gorge Coordinating Committee in September. <br /> <br />D, IS-Mile Reach Gage <br /> <br />DWR provided contract assistance to the Colorado Division of <br />Wildlife and U.S. Geological Survey to facilitate the operation and <br />maintenance of a gage in the IS-mile reach near Palisade, Colorado. <br />A second temporary gage has been installed at the lower end of the <br />IS-mile reach the past 3 years, Information from the 1993 gage <br />operation will be available in January, at which time a report will <br />be prepared and shared with the Water Acquisition Committee and the <br />Colorado Water Conservation Board. This information will be used to <br />support the application for an instream flow for the return flows in <br />the IS-mile reach. <br /> <br />4 <br />
