The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied of the U.S. Government. PREFACE The Yellowstone-Jackson Hole-Star Valley corridor is located within the seismically and tectonically active Intermountain Seismic Belt in westernmost Wyoming and eastern Idaho. The corridor has the highest seismic hazard in the Intermountain U.S. based on the U.S. Geological Survey’s National Hazard Maps. The region contains the heavily visited Yellowstone and Teton National Parks and the rapidly growing areas of Jackson Hole and Star Valley. Although there has only been one large earthquake in this region in historical times (1959 moment magnitude [M] 7.5 Hebgen Lake), abundant geologic evidence exists for the past occurrence of surface-faulting earthquakes of M 7 or greater.

    Pierce and Colman: Submerged Shorelines of Jackson Lake, Wyoming: Do They Exist and SUBMERGED SHORELINES OF JACKSON LAKE, WYOMING: DO THEY EXIST AND DEFINE POSTGLACIAL DEFORMATION ON THE TETON FAULT Kenneth L. Pierce u.s. Geolo:.:Jical. Survey Denver, co Steven M. Colman u.s. Geological Survey Woods Hole, M A Obj::ctives The Teton fault is one of the moot active normal faults in the world, as attested by the precipitous high front of the Teton Range. After deglaciation of northern Jackson Hole arout 15,000 years ago (Parter and others, 1983), offset on the Teton fault eouthwest of Jackoon Lake has tntaled 19-24 m (60-80 feet) (Gilbert and others, 1983). In less than the last 9 million years, offset on the Teton fault has tntaled from 7,500 to 9,000 meters (Love and Reed, 1971). Figure 1 shows how downdropping on the Teton fault results in tilting of Jacks::>n HoJe towards the fault. Submerged paJ.eoohorel:ines of Jackoon Lake may record this downdropping and tilt because the level of Jackoon Lake is controlled by both the furtui.tous ,{X)Sition of the Jake ootlet and the immediate downstream course of the Snake River (Figure 1). The ootlet of Jackson Lake is 12 km east of the fault and from there the Snake River has a very low gradient to a bedrock threshold 6 km further east. Thus the level of Jackson Lake is controlled by the bed of the river east of the hinge line of tiJ.ting (Figure 1). The postglacial history of movement on the Teton fault may thus be recorded by paJ.eoohorelines submerged OOJ.ow the level of the pre-dam Jake.

    WATER BANKING IN IDAHO by Richard M. Rigby1 ABSTRACT Some irrigation projects in the Pacific Northwest are 50 - 70 years old. Storage and delivery facilities were originally constructed based on the best available data and permanent water allocations were made to meet the identified agricultural water needs. The intervening years have brought changes in farming practices and associated water needs, as well as the identifi­ cation of new competing demands for water. When water supplies are fully allocated to existing users, the opportunities to develop new uses may be very limited. Water banking provides an opportunity to temporarily transfer water from an established water right holder to another. Two water banks are presently functioning within the State of Idaho. These banks enable water users to transfer their storage entitlements to other users. Water banking is expressly author­ ized by Idaho law and the existing water banks function with the support and assistance of the Bureau of Reclamation and the Idaho Department of Water Resources. BACKGROUND Minidoka-Pal i sades Project: Two water banks presently function within the State of Idaho, one within the Minidoka-Palisades Project on the Upper Snake River and the other within the Arrowrock Division of the Boise Project on the Boise River. The Upper Snake water bank has existed in some form since the 1930's, and since 1980 it has been formally recognized by State law and regulation. The Boise River water bank began in 1988, partly in response to drought impacts, '~ith State and Reclamation approval. Jackson Lake Dam, near the headwaters of the Snake River in Wyoming, was the first major storage reservoir constructed in the Upper Snake area.
