How it fishes

A Colorado freestone

A freestone river runs free off snowmelt and rain, so it swings hard with the seasons. It blows out and browns up in spring runoff, then drops and warms into summer. The hatches track the water temperature more than the calendar, so you time your trip to the flow and the thermometer.

Flow and gauge

Reading the flows

The Arkansas is metered at USGS gauge 07091200. Watch the trend as much as the number: a river that is dropping and clearing fishes very differently from one that is coming up.

Low

under 200 cfs

Optimal

200 to 700 cfs

High

above 1,000 cfs

Access and regulations

Before you fish

Access and the right to fish are the angler’s responsibility, every time. Public access, private water, and seasonal closures vary along the river, so confirm where you can legally stand and wade before you go. We do not point you to a specific spot.

Read the current rules, license requirements, and any special-regulation water before you go. Regulations change season to season, so check them fresh.
