Abstract
The Total Economic Value (TEV of on-site use and passive use values) of avoiding a 50% reduction in current early summer high flows is estimated for a western urban river in Colorado. Using a contingent valuation method (CVM) survey of households we found that willingness to pay (WTP) for TEV of city households was $234 per year, with most of this value, $207, being use value. Using a second CVM question specifically about recreation use value of visitors yielded an estimated annual WTP of $156 per year. Given the large variances in estimated WTP, the two estimates of recreation use value are not significantly different. Summing up the TEV’s per household in the city yields an annual value of $171 to $255 per acre foot, several times larger than annual water lease rates in Northern Colorado.
