Water Resources Division, is entering its 105th year of activities in Utah. As Utah's demand for water has increased, so has the need for quantitative, unbiased water-resources data and interpretive studies. The Utah District program is designed to provide this information and help the Water Resources Division meet its goal of assessing the quantity and quality of the Nation's water resources. Total funding for the Utah District during fiscal year 1994 was about $5.0 million, which is the same amount as for fiscal year 1993. During fiscal year 1994, the Utah District initiated a National Water Quality Assessment (NAWQA) study in the Great Salt Lake drainage basin. Funding for the NAWQA program during the first year was about $0.2 million but is expected to increase to about $1.5 million during the coming years and create a significant increase in the overall District program. The most significant hydrologic event of the 1994 water year was the return of drought conditions throughout Utah. Precipitation was less than normal throughout most of the State and much less than normal in some areas. Precipitation at 8 of 11 selected recording stations was less than normal. Streamflow at seven index gaging stations ranged from 59 to 79 percent of the long-term mean flow. Spring runoff was deficient because of less-than-normal snowpack, and streams reached baseflow conditions in May or June instead of July or August as is normal. Reservoir storage was adequate because of a larger-than-normal carryover from the wetter-than-normal 1993 water year. Monitoring hydrologic conditions during fiscal year 1994 presented special challenges and illustrated the usefulness of long-term records. As Streamflow decreased, water managers and decision makers required accurate and timely discharge data to ensure that each user received the appropriate amount of available water. The longterm records were useful in placing the current drought into historical perspective and provided a basis for worstcase-scenario planning.

The following report describes the many data-collection activities and interpretive investigations in which the Utah District is involved. The results of this work have traditionally been provided through various types of printed reports: Fact Sheets, Open-File Reports, Water-Data Reports, Water-Resources Investigations Reports, Water-Supply Papers, and Professional Papers, as well as through Utah Department of Natural Resources Technical Publications. Release of information through printed media will no doubt continue in the foreseeable future. However, it is clear that rapid development of electronic communication technology is having and will continue to have a profound effect on the way information is shared. The U.S. Geological Survey is at the leading edge of this new technology.I encourage those agencies and individuals with access to the World Wide Web and the Internet to visit the Utah District Web Page (address listed below) and the many other sites within the Division. One important advantage of this technology is access to "real-time" streamflow information 24 hours a day. In Utah, 49 streamflow-gaging stations and 3 lake-elevation gaging stations on Great Salt Lake provide real-time data, and more stations are planned for the future. The information is used for everything from lifesaving evacuations during flood emergencies to whitewater boating and knowing if the fishing is good. Throughout the Nation, thousands of such sites can be accessed instantly from any computer with Internet access. The ramifications for information transfer are staggering.It is clear that in the future the ways in which information is provided to the public will be quite different than they have been in the recent past. I expect to see a time when all basic data, map information, and interpretive reports are available over the World Wide Web. This is just one more way in which the U.S. Geological Survey helps provide the sound scientific information needed to manage our Nation's water resources.The future promises the continued challenge of helping local, State, and Federal agencies meet their waterresources information needs. I look forward to another active year in which the U.S. Geological Survey helps meet these needs.

The following report describes the many data-collection activities and interpretive investigations in which the Utah District is involved. Although all these activities are providing important data and information, I would like to take this opportunity to briefly discuss two in particular. These are "Assessment of brine shrimp population and nutrients in Great Salt Lake" and "Field demonstration of in-situ chemical barriers to control uranium contamination in ground water." Although these investigations are quite different in technical direction and scope, I believe they provide an insight into how the Water Resources Division and the Utah District provide relevant information to help assess and manage water resources.The harvesting of brine shrimp from Great Salt Lake has, during the past decade, become a high-tech, multimillion dollar industry. Spotter aircraft and high-powered boats are used to maximize harvest, and competition between individual companies is intense. However, no one understands the population dynamics of the shrimp nor the amount that can be annually harvested without threatening the resource. The Utah District, in cooperation with the Utah Division of Wildlife Resources and Utah State University, is helping provide answers to these questions. Information provided from this work is being used by Wildlife Resources to manage the harvest on an almost realtime basis. For those of you with additional interest in this work and in the ecology of brine shrimp, please visit our Great Salt Lake web site at wwwdutslc.wr.usgs.gov/greatsaltlake/saltlake.html Uranium has been mined throughout large areas of the Colorado Plateau in southeastern Utah since about the time of the Second World War. A legacy of this effort is the hundreds of abandoned mines, upgrading facilities, and mills. Many of these sites have contaminated the underlying ground water with uranium and other metals that are hazardous to health. Traditionally, contaminated ground water has been mitigated by the so-called "pump-and-treat" method, which is costly and maintenance intensive. For this reason, only large and highly contaminated sites could be mitigated; smaller or less contaminated sites were simply abandoned and forgotten. At Fry Canyon, the Utah District, in cooperation with the U.S. Environmental Protection Agency, the U.S. Department of Energy, and the Bureau of Land Management, is experimenting with new and less costly technologies for the mitigation of uraniumcontaminated ground water. Several reactive barriers have been installed within a plume of contaminated ground water. The barriers contain materials that react with the uranium and remove it from solution. Although these removal reactions have been known for many years and can be demonstrated in the laboratory, the performance and longevity of the barriers in actual field settings are unknown. Results from this work may provide a cheaper and minimal-maintenance technology to help clean up uranium-contaminated sites throughout the United States. For those with additional ...
