What is a bite calendar?

Hourly activity

0:006:0012:0018:0023:00
Bite activity:highmediumlow

The bite is moderate — fish feed in short bursts. Pressure is dropping — this usually boosts the bite.

Peak bite hours

Best time — 00:00–04:00 and 23:00–23:00 (nighttime activity).

Tactics

Work the cover — snags, weed edges, hole entrances; retrieve the lure with pauses.

Lures

In clear water, natural colors work best: live-bait bottom rig or large bottom bait.

Gear

No special gear needed — seasonal clothing will do.

Summary

An average day — best chances during peak windows.

Why this forecast

The computed water temperature is around 71 °F — inside the 70–86 °F comfort range for Flathead catfish, so baseline activity is high.
