A maximum difference conjoint model was used in developing a questionnaire to assess lay preferences for hypothetical water level management in Dog Lake Reservoir, and for streamflow regime manipulation in the Kaministiquia River in northwestern Ontario. The profiles of water management alternatives included water levels in Dog Lake and varied streamflow regimes in the Kaministiquia River in spring, summer and fall. The respondents were shown relevant management profiles and were asked to indicate the most preferred and the least preferred item in any profile. The results of the survey indicated that the cottagers on Dog Lake preferred raising water levels slightly during the spring walleye season and maintaining the current levels in the summer for water-based recreation. Preferences were reversed for the fall season, when the main concern was beach erosion due to wind-induced wave action. Flow in the Kaministiquia River was considered to be marginally important for kayaking, but there was less concern for hydro-power generation from the Kakabeka Falls or for the flow over the falls. A significant number of downstream respondents in the community of Kakabeka Falls preferred a 20 increase in streamflow during all of the three seasons. They had some concerns about a lesser flow in the Kaministiquia, especially during the fall salmon spawning season, but were indifferent about water levels in Dog Lake. The results of the model provide a basis for improving Ontario Hydro#x2019;s operation of the Dog Lake Reservoir.
