What’s biting

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

Largemouth Bass

Largemouth bass

Micropterus salmoides

68MarginalTonight 9 pm to Monday 4 am

Water

No water reading here right now. Largemouth bass bite in 55–85° water, best near 72°.

Why

Light breeze — ruffles the surface so fish spook less, and casting is easy. Holds 3–25 ft down.

Keep

12" minimum · 5 a day

Open. Keep fish within the limits. Maryland nontidal waters: 12" minimum (or as set by special regulation), 5 bass a day combined with smallmouth, kept only Jun 16 to the last day of February. Catch and release is allowed at all times. Bass may not be used as bait.

Fishing report

Maryland DNR, Nov 4

Freshwater Fishing. Although the fall trout stocking program has reached its end, there are still plenty of opportunities for put-and-take anglers in the many community ponds and reservoirs that were stocked. If anglers try switching from Powerbait and work the waters distant from the usual stocking locations with spinners, they might be surprised with the trout that are still there. The delayed harvest and catch-and-return trout management waters will provide catch-and-release fishing from now until June. At that time there will be dates when they revert to put-and-take for the summer months. More information about the special trout management areas is on the DNR website.

Quoted from the Maryland DNR weekly fishing report. Reports are what anglers and biologists saw that week, not a forecast.
