Access roads leading to the upper portions of the South ajid North 

 Forks of the ITorth Fork terminate at the Bench Mark Ranger Station on the 

 former and near the Ear Mountain Ranger Station on the latter «, "Bench 

 Mark" and "Teton" were used to designate fishing in the two forks by fish- 

 ermen who passed through these two points. Through the cooperation of re-- 

 sort o^vners, packers. Forest Service personnel, and others^ it was possible 

 to maintain a record of such use by making v/eekly trips to these areaso 



A 2=week (June 24 to July 7) intensive census of Wood -Lake was made 

 by means of a checking station. 



Accoionting for fishermen using the 22 miles of the main river below 

 Diversion Dam presented a special problem, since there were several trails 

 leadinfT to the river from the main road and it v/as not feasible to use 



O 



checking stations except for the extreme upper one -half mile,, A census 

 was made of the upper 6 miles (Lower River A) and lower 5 miles (Lower 

 River B) of this reach of stream by means of periodic patrols i but the in- 

 tervening 11 -mile section (Lovrer River C) was checked only occasionally 

 because of limited pressure' and' difficulty in traversing the roughi road • 

 along the river. Fishermen using Pishkxm Reservoir, Pishkun Canal, Tunnel 

 Lake, and Split Rock Lakes were generally checked as they passed through 

 checking stations at Pishkun Reservoir or below Diversion Dam, but periodic 

 patrols also were made of these areas. Willow Creek Reservoir was censused 

 by patrolling. Checks were made of the above areas on an alternate -week 

 basis. 



Information concerning the number of fishermen in the party, hours 

 spent fishing, type of fishing, residence and sex of fishermen, the catch 

 by species, and the cost of the fishing trip was recorded. Weights and 

 lengths of a nonselective sample of fish in creels also were obtained. 

 Estimates of the total weight of the catch were based on the average 

 weights thus obtained. The data were recorded on punch cards, which facil- 

 itated fast and accurate compilation. 



Creel-census data were collected on a party basis. All the fishennen 

 in one boat or the occupants of one or more automobiles who fished to- 

 gether were treated as a party. By using this system, it was usually possible 

 to secure the necessary information from one member of the party, thereby 

 enabling the crews to accumulate considerably more data than would other- 

 wise have been possible. 



Creel data were compiled on a biweekly basis, and estimates of fishing 

 and yield were based on the respective compilations o- Juj;l'^ent factors were 

 used in arriving at estimates of fishing and yield for Lower River C,

Trip expenditures, which included the expenditure per day for food, 

 lodging, bait, reiltals, and miscellaneous items such as refreshments, film, 

 ice, and similar items, v/ere recorded on a party basis for each party con- 

 tacted. Average trip expenditures and round-trip mileage per person per 

 day were computed for four major units of the study: (l) above Gibson 

 Reservoir, (2) Gibson Reservoir, (3) below Gibson Reservoir, and (4) Wood 

 Lake, A rate of 7 cents per mile was used to determine transportation costs,
