am in particular, is the period during which Spilhvay launch capacity is most severely tested. 

 A review of these day suggests that time-slot management is most needed for the 7:00 am 

 hour on Saturdays, when the mean number of launches (25.7) approaches the theoretical 

 peak launch capacity (disregarding river otters and float tubes, however, the mean number 

 of launches for this time slot is <20). The Forest Service should consider extending time 

 slot management from 6:30 am to 9:30 am on Saturdays during the floating season. 



The peak for commercial boat launches is in the hours of 7:00 to 9:00 am. It should be 

 noted that commercial boat launches do not now appear to present much of a management 

 problem in terms of competition for Spillway launch fadlities during peak periods. Indeed, 

 given the allocation of 2,440 user-days in Segment A, this amounts to just over 4% of the 

 total number of people launching at the Spillway during the 1990 peak season. Even 

 assuming a group size as low as 2.5, this would amount to a total requirement of less than 

 1,000 launches per year to service the allowed commercial use. Thus, even if all the 

 commercial boat launches were concentrated in the most desirable hours of the most 

 desirable seasons, they would use only about 5% of the total number of launches available 

 between 7:00 and 10:00 am over the course of the peak season. Moreover, commercial 

 guides try to avoid high float days, and this is reflected in the fact that the proportion of use 

 attributable to commercial outfitters is at its lowest on the peak day of the week (Saturday) 

 and during the peak months (July and August). 



4.7.4 Enforcement 



It is important to recognize that limits have already been set on the use of the Green River 

 and its resources in the form of fishing, watercraft, and safety regulations. About one-third 

 of Green River users would like to see greater enforcement of these limits (Figure 26). 

 Although 65% of mailback respondents felt there was no problem with enforcement of laws, 

 rules, and regulations, 20% felt there was a moderate problem and 15% noted a serious 

 problem. The need for greater enforcement was voiced by 6% of intercept respondents and 

 25% of the mailback respondents. It was the single most cited comment on the mailback
