(b.) Major Premise: Another issue pertaining <br />to the effect of low and fluctuating <br />flows on recreation benefits and econom- <br />ics is the carrying capacity of the Glen <br />Canyon tailwater reach for angling and <br />boating activities. Data gathering to <br />clarify carrying capacity issues will be <br />carried out as a part of the study of the <br />economic benefits of angling. <br />Estimated Cost: Inclusive with Item 4(a) <br />above; Responsible Parties: Private <br />consultants (Heberlein Baumgartner <br />Research Services [HBRS)), NPS (GCNRA) ; <br />Time to Complete: To be included in <br />fiscal year 1990 studies. <br />(c.) Major Premise: The economic benefit <br />values developed during GCES Phase I <br />studies for the day-use rafting and <br />whitewater boating recreational com- <br />ponents are believed to be a correct <br />representation for use in the 1989 study. <br />These values will be reevaluated to <br />ensure their validity. <br />Estimated Cost: Inclusive with Item 4(a) <br />above; Responsible Parties: HBRS; Time to <br />Complete: 2 years. <br />C. ENDANGERED FISH STUDIES <br />1. Initiate conservation measures and <br />monitor humpback chub. <br />Major Premise: Initiation of the conservation <br />measures (to be outlined in the 1989 Biological <br />opinion) is necessary to protect the endangered <br />humpback chub. Monitoring trips to evaluate <br />humpback chub population and habitat in the main- <br />stem and Little Colorado River are required and <br />will continue while specific conservation measure <br />studies are developed. A decision on the conserva- <br />tion measures is expected by March 15, 1989 (as per <br />Fish & Wildlife Service, Assistant Regional <br />Director Jim Young, 2/1/89). <br />Estimated Cost: $25,000 <br />11
