Abstract

The Snake River corridor is located in the eastern portion of Grand Teton National Park. The primary use occurs between Pacific Creek and Moose (park headquarters); however, most of the concessioner trips (approximately 75%) are operated from Deadman's Bar to Moose (Fig. 1). From Pacific Creek to Deadman's Bar is approximately 10 1/2 miles, with an elevation decrease of about 100 feet. The second major leg of the river (to Moose from Deadman's Bar) is about 10 miles long with a relief of approximately 180 feet. The flow of the water will vary considerably from the early season runoff to the late season dry spells, also, the flow is determined by the flow outlet at the Jackson Dam. Even with the seasonal variation, the trip is a scenic float with very little to no whitewater conditions. Present management is concentrated on regulation of the concession floater with little emphasis on controlling the private floater. For the concessioner, he must put in and take out as designated on a scheduled basis. He cannot stop and allow the visitor to go ashore except at a few designated points (primarily for a noon meal). Each concessioner is required by contract to present an interpretive program. Project Number 194.
