Informal recreation activities derived from Colorado River water flow produce economic benefits. In order to prove this, we used a contingent valuation method (CVM) , based on a survey applied to 100 visitors originating mainly from San Luis Rio Colorado; a single bounded econometric analysis was performed on the referendum question of willingness to pay (WTP) . Many regressions using Probit and Logit models were run to obtain different estimators of central tendency of wtp. The estimated annual profit from such activities is between 1.9 and 6 million pesos a year.
