Black crappie

3/10 · Weak

Hourly activity

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

The bite is moderate — fish feed in short bursts. Pressure is rising — activity tends to be more subdued.

Peak bite hours

Best time — 07:00–08:00 (dawn bite) and 20:00–22:00 (dusk bite).

Tactics

Look for drop-offs and gaps in the weeds, retrieve slowly, lingering over promising spots.

Lures

The water's turning murky — go with bright, noisy lures: small jig or minnow bait.

Gear

Bring a warm jacket — it's noticeably colder on the water than on shore. Rain is expected — don't forget a rain jacket or a waterproof shell.

Summary

An average day — best chances during peak windows.

How this forecast is calculated

Why this forecast

The computed water temperature is around 53 °F — colder than the 57–75 °F comfort range for Black crappie: the fish conserves energy and takes more cautiously.
