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.

    Source

  • 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.

    Source

  • 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.

    Source

  • Buena Vista access-area coordinate38.8472488, -106.1222166 (CPW facilities GIS feature 2120)

    CPW maps a Boat Ramp feature within the Buena Vista SWA access area; its AHRA page lists Buena Vista Whitewater Park as a public boat-ramp/slide site managed by the town. This point locates the launch area and is not a surveyed ramp-toe coordinate.

    Source

  • 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.

    Source

  • 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.

    Source

  • 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.
