NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Named public corridorGranite Boat Chute through Numbers/Fractions to Buena Vista Whitewater Park
CPW documents the 32-mile Leadville-to-Buena Vista section, names the public access chain, and identifies the Numbers/Fractions Class III-V corridor below Granite.
- Direct live gauge and thresholdsUSGS 07087050 Numbers/Below Granite; CPW 900 / 1250 / 2400 cfs advisories
USGS supplies direct discharge and stage telemetry. CPW ties wetsuit guidance above 900 cfs, Pine Creek no-run guidance above 1250 cfs, and Numbers no-run guidance above 2400 cfs to this gauge.
- Lawful endpoint accessGranite Boat Chute AHRA access to Buena Vista Whitewater Park
CPW lists both sites as river access, with boat ramp/slide and portage infrastructure at Granite Boat Chute and a public boat ramp at Buena Vista Whitewater Park.
- Safety boundaryAdvanced Class III-V; marked chute/portage only; exit at Buena Vista
CPW identifies the class and named rapids; the route must preserve the diversion/portage boundary and current same-day scouting requirement.
- Camping and logisticsAHRA camping at selected sites; separate reservation/compliance required
CPW documents Railroad Bridge and selected AHRA camping while the endpoint pages establish public access. Do not infer private-bank or unrestricted dispersed camping.
- Rights-clean image decisionApproved Wikimedia Commons CC BY 4.0 Granite Boat Chute context image
The selected Granite Boat Chute image is published under CC BY 4.0 and retains author/license attribution; it is context imagery rather than a coordinate claim.
- Duplicate separationDistinct Upper Arkansas Numbers/Fractions reach
This route is separate from the existing Upper Colorado, Clear Creek, and Cache la Poudre routes by river, endpoints, gauge, and hazard boundary.
