Recreation Information Needs

 RIN 1What is the total market and non-market value 

of the recreational use of the Colorado River 

ecosystem downstream from Glen Canyon Dam? 

 RIN 2 What is the current total annual market value 

of the Lees Ferry trout fishery to the regional 

community? What are its components; i.e., hotel 

and restaurant, guides, retail purchases, etc. and 

what are its non-market values?

 RIN 3 What is the current total annual market value 

of Lees Ferry recreational boating industry, and 

what are its non-market values?

 RIN 4 How have total annual use and market 

values for the Lees Ferry trout fishery and 

recreational boating changed in the pre-and post – rod periods?

5
Recreation Information Needs

 RIN 5 Do Lees Ferry recreational boaters and sports 

fishers express a significant difference in willingness 

to pay under differing flow conditions? 

 RIN 6 How has demand for Lees Ferry and Grand 

Canyon recreational boating (including rafting to 

Lake Mead) and Lees Ferry sport fishing changed 

over the pre-and post-rod periods? 

 RIN 7 How has crowding, camp size, multiple 

campsites in an area, etc. affected the Grand 

Canyon recreation experience and expressed 

market and non-market values

 RIN 9 How does the social benefit of the Lees Ferry 

trout fishery differ for walk-in only and boating 

anglers?

HYDROPOWER INFORMATION NEEDS

 HIN 1. Determine and track the impacts to federal 

hydropower consumers from implementation of Record of 

Decision dam operations and segregate those effects from 

other causes such as changes in the power market.

 HIN 2 What would be the biophysical effects (list) on the 

Colorado River ecosystem and marketable capacity and energy 

of increasing the daily fluctuation limit?

 HIN 3 What would be the biophysical effects (list) on the 

Colorado River ecosystem and marketable capacity and energy 

of increasing the up ramp and down ramp limit?

 HIN 4 What would be the biophysical effects on the Colorado 

River ecosystem and marketable capacity and energy of 

raising the maximum power plant flow limit above 25,000 cfs?

 HIN 5 What would be the biophysical effects (list) on the 

Colorado River ecosystem and marketable capacity and energy 

of lowering the minimum flow limit below 5,000 cfs?

7
HYDROPOWER INFORMATION NEEDS

 HIN 7 What are the projected costs to 

federal hydropower customers associated 

with the various alternative flow regimes 

 HIN 8 Develop rapid response capability with 

models to evaluate impacts of alternative 

proposed flow scenarios on all resources

 HIN 9 Develop total market and non-market 

impacts on upper basin water users from 

proposed alternative dam operations

 HIN 10 What are the socioeconomic benefits 

and costs of Glen Canyon Dam operations 

and experiments to tribal communities?

 HIN 11 Define the base case for power 

generation for change case analysis?

8
HYDROPOWER INFORMATION NEEDS

 HIN 12 What are the market impacts of flow 

regimes on costs to federal hydropower customers 

relative to Pre-Rod?

 HIN 13 What are the non-market impacts of 

various flow regimes on federal hydropower 

customers relative to Pre-Rod? 

 HIN 20 Are there non-market values associated 

with Glen Canyon electrical power, and if so 

specify and determine these values

 HIN 21 Are there non-market values associated 

with water released through Glen Canyon Dam, 

and if so specify and determine these values 9
Cultural Information Needs

 CRIN1 What are traditionally important resources, and 

locations for each tribe and other groups 

 CRIN 2 What is the baseline measure for resource 

integrity of cultural resources? 

10
Questions to INs

 HIN 14 What is the total economic impact to upper basin 

water users from changes to power generation from base 

case?

 CRIN 4 What are the market and non-market values of 

hydropower generation from HFEs to tribal communities?

 CRIN 5 What are non use and non-market values for 

different cultural resources from tribal perspective

 GIN 1 Determine impacts on marketed hydropower and 

recreation values of alternative flow scenarios with real time 

models to support decision making
