Surveys of experienced river users are one effective way for developers and owners of hydropower projects to determine the effects of flow releases on recreation activities such as white-water rafting. This type of survey was used for determining the effects of flow changes on white-water boating on the Colorado River in the Grand Canyon.

Effects of flows on whitewater boating can be profound, but there is little evidence that shows impacts on specific trip attributes. A normative approach developed in other resource management applications is used to develop evaluative information about streamflows for whitewater trips in the Grand Canyon, below Glen Canyon Dam. A mailed survey was completed by 134 commercial river guides and 152 private trip leaders. Questions covered the effects of flows on trip quality and scheduling, quality and safety of rapids, camping, and visits to off-river attraction sites. The study identifies the diversity of attributes affected by flows, evaluates specific effects of flows on those attributes, and presents methods for data collection, analysis, and interpretation. Such information is particularly helpful for developing flow requests, integrating recreation needs with the needs of other resources, and developing flow scenarios for dam operation. Changes in operating regimes for Glen Canyon Dam are being considered, based on this and other research conducted as part of the Glen Canyon Environmental Studies. -from Authors
... To address the increasing impacts of recreation activities, carrying capacity was introduced in recreation resource management in the early 1960s. Some earlier contributors (e.g., [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]) have paved the way for many carrying capacity studies in recreation and tourism resources today. ...
