What’s biting

Each species is scored against its own water-temperature range and tide preference, then wind, weather and warnings. The rules are Wyoming non-tidal regulations for these waters.

Walleye

Walleye

Sander vitreus

80Worth the tripTomorrow, 1 am–11 am

Water

No water reading here right now. Walleye bite in 50–72° water, best near 62°.

Why

Walleye feeds aggressively in low light. Light breeze — ruffles the surface so fish spook less, and casting is easy. Holds 10–40 ft down.

Keep

6 a day

Open. Keep fish within the limits. Wyoming statewide: 6 walleye a day. Bighorn and Wind River drainage walleye and sauger must be kept whole until you are off the water.

Tough Creek and Brannon offer public ramps and shoreline access.
