Bass and pickerel on thin water as Pine Barrens streams drop to summer lows

What's biting

What's next

With the Mullica River gauge sitting at 25.8 cfs and no temperature data available, the next few days will hinge on air temperatures and incoming rainfall. Midsummer frontal passages are worth watching closely: even modest rain can meaningfully bump flows on the Pine Barrens' small, sandy-substrate watersheds and trigger feeding activity on otherwise sluggish bass and pickerel.

If conditions remain dry and warm, expect water clarity to stay high on the clearer Pine Barrens tributaries and moderately stained on the more tannin-rich backwaters. In low, clear water, fish gravitate toward shade: overhanging cedar, root tangles, and the deepest channel bends become the most productive holding zones. Plan sessions around the low-light bookends. The first two hours after sunrise and the final hour before dark are far more productive than midday, when surface temperatures suppress feeding for extended stretches.

For the Delaware River mainstem, serious catfish season is now underway. Channel and flathead catfish become increasingly active as bottom temperatures rise into their summer feeding range. Cut bait and nightcrawlers fished on bottom rigs after dark along deeper river bends are the traditional approach. The First Quarter moon this week provides moderate nighttime light, a useful window for catfish sessions that run late.

Smallmouth bass in the upper and middle Delaware are post-spawn and distributed across summer structure. Low, clear flows push finesse presentations to the front: small tube jigs, drop shots, and soft-plastic crawfish worked along broken rock and boulder fields are reliable. Best windows remain early morning and late evening.

On the Pine Barrens side, chain pickerel and largemouth bass are the primary freshwater targets. Slow-rolled soft plastics, small willow-blade spinnerbaits, and shallow crankbaits worked along vegetation edges all produce during low-light windows. Watch the gauge: if the Mullica River climbs above 40 cfs after a rain event, expect the bite to wake up system-wide.

Context

Late June is historically a turning point for NJ freshwater fishing. The spring stocking pulse from NJ Fish & Wildlife, part of the state's annual put-and-take program, has largely run its course for Pine Barrens-adjacent waters by this date. Holdover trout are rare in these streams given warming summer temperatures, and angler attention shifts decisively to warmwater species.

For the Pine Barrens, flows in the 20 to 30 cfs range on the Mullica River gauge are consistent with historical late-June norms. The region's sandy, porous soils drain quickly after rain events and don't retain much summer baseflow. The tannin-stained, slightly acidic water that defines these streams moderates temperature somewhat relative to clearer systems, giving warmwater species a marginally wider feeding window than surface temps alone might suggest. By late June, however, the midday bite window has tightened considerably.

On the Delaware River, late June traditionally marks the full entry into summer catfish season, with channel and flathead catfish active through the warmest months. Smallmouth bass fishing on the upper Delaware historically peaks in May through mid-June. By late June, fish are post-spawn and spread across summer holding structure, requiring more targeted presentations than the concentrated pre-spawn and spawning windows.

Direct comparative season commentary from freshwater sources is limited this cycle. The bulk of NJ angler reports skewed toward coastal and offshore fisheries, and even those reflected variability. Northern NJ charter captains covered in The Fisherman — Northern NJ noted that June's sea bass fishing ranked among the poorest in recent seasons, with multiple boats pivoting to summer species. The theme of a variable, front-disrupted late spring appears consistent across both inshore and freshwater environments, suggesting summer patterns may be arriving on a slightly scattered schedule compared to recent years.
