Gunnison River — Grand Junction
Large lower river; runoff, turbidity and heat can change rapidly.
Colorado · public-access reaches. This page is what the desk knows about the water itself. What it is doing today — flow, water temperature, weather, and the hazards those produce — is a reading with a date on it, and it lives in Trip Prep.

Directory review

The fleet directory names this water differently, and nothing records which of its records is the Gunnison River — Grand Junction this desk plans on, so the desk will not borrow a review date from any of them. Linking them is a review task for the directory’s owner, not a guess for this page. The directory’s record:

How access works here
Mixed — some drive-to, some walk-in
This reach mixes drive-to and walk-in access. Some sections are road-adjacent, others need a walk from public ground.
Launch · Launch type varies by access point. Confirm on the agency map before you tow a boat to it.
Parking · Parking is at designated access points. A pullout that looks fine is not automatically legal or safe to leave a vehicle in.
Colorado's Fishing Atlas maps public water. Colorado does not have a general right to wade private streambeds — a reach is public where the land or an easement is public.
Gauge
A public gauge is mapped
Flow and water temperature for this water are read from USGS site 09152500, Gunnison River near Grand Junction, CO. It is an official public gauge, not a fishing pin: it describes the river at one point, and the reach you stand in may be doing something else.
