Applying these methods to river recreation yields annual (e.g., lease price) values of $10 an acre foot for rafting and $20 an acre foot for kayaking in
These estimated values are in the same range as recent annual water lease transactions ranging from $10 an acre foot just for recreation up to $40 an acre foot for fishing and general instream flow. Water right purchases for recreation average $1,200 an acre foot while for fish it averages about $500 an acre foot, and for general instream flow about $700 an acre foot. These actual water purchases and leases suggest the non market values of water estimated using the travel cost and contingent valuation methods are reasonable.
Passive use values per household to maintain instream flows for rare fish such as the Silvery Minnow in the
