A subsequent meeting was held with David Wagner of the Bureau, who directed the Grand Canyon Environmental Studies. Mr. Wagner went over all the studies involved in the project and emphasized the need for accurate and defensible data and results. Following this meeting, a scope of work was developed for the Flaming Gorge peaking power study. The work plan for this effort is displayed in Appendix A. Because of a need to have flow and stage information near habitat sites, three additional sites were added to the SSARR network (see Figure 1). These sites were located at Mitten Park in Dinosaur National Monument, Ouray National Wildlife Refuge, and at Tia Juana Bottom below the confluence of the White and Duchesne Rivers. Based upon Mr. Wagner's comments on data integrity and defensibility, continuous stage recorders would be used to develop the stage discharge relationship at each new site. III. METHODOLOGY To accomplish the stated objective, a hourly hydrology model was selected and a work plan was established to gather the information necessary to set up the model at desired locations. The model output was then compared against accepted observed hydrographs until recorded and computed results were within ranges. The model would then be considered fully calibrated and ready to evaluate different operational scenarios for Flaming Gorge Reservoir. IV. STUDY IMPLEMENTATION To implement the study, six continuous stage recorders were obtained from the Bureau under the excess property program. These recorders were repaired and tested during the winter, and prepared for installation in the spring of 1987. The first recorder was installed at the Ouray National Wildlife Refuge in March of 1987, and operated until late June when the water in the Green River dropped below the level of the river equalization tube (see Figure 2.) The elevation of the recorder was lowered in October of 1987, and operated through the winter with minimal maintenance. The second recorder was installed at Mitten Park in Dinosaur National Monument during April of 1987. Because of the remote location of Mitten Park, the pit for the recorder had to be dug by hand and could not be placed at an optimal elevation because of the stage of the Green River. The recorder operated through the runoff season, but ceased recording useful data in late June when the river dropped below the river equalization tube. This recorder was reinstalled to a position 4 feet lower during a mid- July test period when releases from Flaming Gorge were dropped to 800 cfs. The Mitten Park recorder then operated through the winter and up until mid-May 1988, when the recorder was removed to prevent damage by the spring runoff. The recorder was reinstalled in late June 1988 after the spring runoff. 2
