Starting in water year 1997 and continuing through at least water year 2003, data collection at the Conconully climate station stopped during the winter months, generally for November through February. As a result, the available records of overlapping measurements of daily precipitation and daily minimum and maximum air temperatures for the Conconully climate and Conconully CCR Hydromet stations is generally limited to non-winter months between August 1999 and the present (2006). If year-round data collection for the Conconully station were resumed, the resulting overlapping records would allow more thorough testing of the assumption made in this study that the daily precipitation and air temperatures measured for the Conconully CCR Hydromet station are equivalent to the daily precipitation and air temperatures measured for the Conconully station. Confirmation of this assumption is important because the use of the precipitation-runoff model developed in this study for ESP forecasts depends on real-time measurements for the Conconully CCR Hydromet station to be equivalent to the non-real-time measurements for the Conconully climate station.
Dames and Moore (1999) reported that starting in 1997, releases from Conconully Reservoir were measured only through the outlet tunnel. This means that the measurements no longer include seepage below the dam and uncontrolled spills. It would be helpful if a stream gage were installed in Salmon Creek downstream of the spillway of Conconully Dam to measure all runoff from the upper Salmon Creek Basin.
Improved availability of climate and streamflow data for Salmon Creek Basin should enable improved calibration of the precipitation-runoff model described in this report. The improved model would increase the reliability of simulated historical streamflows and ESP forecasts of streamflows in the Salmon Creek Basin. This in turn would make the precipitation-runoff model a more reliable component of the DSS that Reclamation plans to use to study the water resources of the Salmon Creek Basin.
