The primary goals of the study are to obtain information on the distribution, density, movements, activity patterns and behavior of otters on the Snake River from Jackson Lake Dam to Moose. Most observations were concentrated along the 3.5 mile section from the dam to and including the Oxbow. This report covers field work during the periods of March 7-17 and August 11 - September 25. No otters were seen in March but they were observed for 28 hours during 88 hours afield in August and September. Additionally, Mr. John Turner of Triang1e-X Float Trips and Mr. Dick Barker of Barker-Ewing Float Trips were most cooperative in obtaining sightings of otters made on the river by their parties between Deadman Bar #2 and Moose.
