TY - Generic T1 - Northern Sierra snow of '83 and '95 'a comparison' T2 - 64th Annual Western Snow Conference Y1 - 1996 A1 - Marron, J.K. KW - Snow survey AB - The 1995 snowpack in the Sierra changed dramatically during the year and ended with one of the highest years on record. Much to the chagrin of those hearty surveyors who sampled snow during the winter of '83 the newer samplers began claiming that the winter of '95 was much worse and the sampling of course was the hardest and deepest ever. This paper will compare the winter of '95 and the winter of '83 in two ways. The first will be to use the reported averages of each of the snow courses and secondly the amount of snow removed from the snowpack on the survey. These two analyses will provide information on me resulting snowpack and the difficulty in obtaining the measurements JF - 64th Annual Western Snow Conference T3 - Proceedings of the 64th Annual Western Snow Conference PB - Western Snow Conference CY - Bend, Oregon UR - sites/westernsnowconference.org/PDFs/1996Marron.pdf ER - TY - Generic T1 - Reservoir operations guides - application on three reservoirs T2 - 57th Annual Western Snow Conference Y1 - 1989 A1 - Marron, J.K. A1 - Farnes, P.E. A1 - Pacheco, C. KW - Management technique, Operation Goal, Reservoir Operations, Water Supply Forecasts AB - The Soil Conservation Service, Water Supply Forecasting Staff developed and released a technique and software to help water users manage reservoirs to achieve the goal of the structure whether that goal was to optimize water supply for irrigation or reduce damage done by excess runoff. the reservoir management technique reviewed here bases nanagement decisions on water supply forecasts. The technique has been applied on several reservoirs in the west. Three reservoirs were selected for review. All of these reservoirs are dominated by snowmelt runoff. This paper will review the possible implications of the application of this process.

KW - Precipitation & Temperature Distribution, Precipitation Form, Probability, SNOTEL AB - A distributed parameter, deterministic, physical process model known as the Precipitation Runoff Modeling System (PRMS), developed by George Leavesley of the US Geological Survey is used to determine the feasibility of using telemetered as well as manually measured snowpack and precipitation information to develop a forecasting tool for use in the East Fork of the Carson River, Nevada. Sources of error in streamflow simulations are a result of the incorrect indentification of the form of precipitation, and the simulation of the highly variable distribution of precipitatioN and air temperature on the watershed. Procedures that identify the form and improve the distribution of precipitaton on the watershed are developed and tested. A probability analysis technique developed for use with PRMS is reviewed and possibilities for its application and further development are discussed.

A1 - Davis, R.T. KW - Automated, Event, Probe, Remote site, SNOTEL, Subsystem AB - The eruption of Mount Saint Helens on May 18, 1980 demonstrated the need for an event identification system to monitor changes in the snowpack caused by either meteorological or volcanic contributions. An event system was developed and installed on Mount Saint Helens that demonstrated both the flexibility and expandability of the Soil Conservation Services' Snow Telemetry System (SNOTEL). With minor modifications, as demonstrated by the Mount Saint Helens event system, there is a potential for an addition to the SNOTEL system. The flexibility of the system shows different data needs can be solved by use of the SNOTEL system.
