River-Based Recreation

River recreation encompasses an array of activities, but for purposes of SMPs, the primary activities are boating (whitewater kayaks, canoes and rafts, stand up paddle boards and tubers) and angling. These activities support a number of local economies and jobs (especially in mountain resort towns), as well as a desired quality of life for residents. Even municipal developers utilize the state’s natural environment as a primary marketing tool to attract businesses and high-income workers. Water management activities can have both positive (reservoir releases) and negative (diversions and channel spanning infrastructure) impacts to river-based recreation. River-based recreational opportunities identified in SMPs should not have negative impacts to stream ecology.

SMPs can assess boating opportunities (both existing and desired) by surveying user preferences for certain flow ranges and comparing those to existing flow conditions, examining the adequacy of access points, surveying for instream structures that impede safe boat passage, and cataloging the use/desire for in-river infrastructure like whitewater parks.

Angling recreation includes float fishing and wade fishing. Assessing angling recreation could involve user-preference surveys that relate flow levels to angling success or user enjoyment. Because the presence of desirable fish species is directly related to the angling experience, reductions in aquatic habitat quality or availability imposed by upstream water depletions may impair angling. Lack of river access points may similarly limit this use.

Potential Data Sources

American Whitewater has conducted user preference surveys for boating flows in several Colorado rivers. Contact AW staff in Colorado for additional information.

Approaches

San Miguel River

Montrose County acquired conditional water rights to the San Miguel River in southwest Colorado in hopes of building multiple new reservoirs. American Whitewater (AW) assessed the impact these conditional storage proposals would have on existing recreational opportunities. Using flow ranges that AW defined through a previous study and historic hydrologic data, AW determined the number of boatable days (days throughout the year when flows are above minimum and below maximum acceptable levels) in dry, dry average, wet average, and wet years. Montrose County supplied simulated daily depletions associated with three project alternatives and AW used these simulated depletions to recalculate the number of days when boatable flows would have been available with these reduced flows.

North Fork of the Gunnison

As part of its Environmental and Recreation Needs Assessment, the Western Slope Conservation Center assessed the current state of recreation infrastructure, activities, and opportunities. This information was gathered through interviews with riverfront landowners, river recreationalists, and other river stakeholders. For each river reach, conclusions and recommendations were developed and prioritized.
