About Green River

Green River is a Wyoming destination for a major fishing and paddling river corridor.

Make the Most of a Green River Day

Match the route, launch, facility, or turnaround time to wind, precipitation, temperature, smoke, water, snow, road access, and daylight. Keep a shorter or more sheltered backup ready.

Weather Tips for Green River

  • Check official access notices, alerts, road or trail conditions, fire restrictions, and local forecasts before leaving.
  • Check river flow, reservoir wind, cold-water conditions, waves, lightning, and verified local ice reports before water plans; no forecast alone proves that ice is safe.
  • Carry layers, water, navigation, sun protection, and seasonal traction or flotation appropriate to the activity.
  • Allow extra time for remote roads, mountain passes, wildlife, spring runoff, wildfire smoke, and limited winter daylight.
