Stripers and spawning bass prime the Delaware as the shad run winds down

What's Biting

What's Next

Looking ahead, the Memorial Day weekend warming trend noted by multiple NJ sources should push water temperatures higher across the Delaware drainage. For freshwater anglers, this is a key inflection point: bass on the spawning beds will become increasingly accessible as late-May activity reaches its peak, and the first post-spawn fish will begin staging in shallow feeding zones adjacent to the flats.

The shad clock is running down. Old School Outdoors in Ewing places the run's wind-down right at the start of June, meaning this weekend likely represents the final reliable window for shad in the Trenton-to-Lambertville corridor. If a shad trip has been on your calendar, do not delay. Target the tidal sections of the Delaware in the morning hours and time your drifts to the current change, as shad tend to push upstream on the incoming tidal flow. The first-quarter moon phase provides moderate current influence that can concentrate fish in predictable runs.

For bass, Tackle World identifies June as the prime spawning month across all waters, but late-May beds are already active. Soft plastics and finesse presentations work best in the calm backwaters and shallow flats of the Pine Barrens drainages, where clear tannic water allows sight-fishing on visible beds. On the Delaware proper, bass are staging along structural transitions between fast and slow water.

Trout anglers should take Tackle World's caution seriously: if the dry weather continues through June, stream fishing will slow as falling water levels produce low, warm, and clear conditions. The D&R Canal, which holds more stable water than freestone tributaries, is the more reliable option as stream flows drop. Target early mornings before warming air temperatures push surface temps up.

Pickerel in the Pine Barrens cedar streams should remain in play through early June. As water levels recede, concentrate on woody debris piles, undercut banks, and fallen timber holding fish in slower pools.

One access note worth flagging before the holiday weekend: NJ Fish and Wildlife News has announced seasonal closures in five Wildlife Management Areas effective May 21 through September 7 for public safety reasons. Anglers accessing Pine Barrens WMAs should verify which areas are affected before heading out.

Context

Late May on the Delaware River and the Pine Barrens drainages typically marks the transition from peak spring migration to early summer patterns. The shad run historically reaches the upper tidal Delaware by mid-to-late April and wraps up in the Trenton and Lambertville corridor by early June. By that measure, this season appears to be tracking on schedule: Old School Outdoors' report of a June wind-down is consistent with long-standing patterns in this stretch of the river.

The striped bass presence in the tidal Delaware is also seasonal and expected. Spring stripers push upriver following shad schools and typically hold through early June before water temperatures push them back toward the coast. The current reports from The Fisherman's NJ/DE Freshwater contributors place the action exactly in that window.

What stands out this year is the dry-weather pattern. Tackle World specifically flags falling water levels from a lack of rain heading into June. In typical late-May seasons, periodic thunderstorms refresh stream flows in the Pine Barrens and northern NJ tributaries, triggering renewed trout and bass activity in smaller waters. A dry stretch compresses that window and can push trout into deeper, cooler pools earlier than usual. Stream anglers targeting Pine Barrens tributaries should monitor levels carefully before making the trip.

Overall, the picture from The Fisherman's NJ/DE Freshwater contributors is of a productive May: crappie reliable statewide, largemouth on the beds on schedule, trout decent in stocked waters, and pickerel still active in the cedar streams. That aligns with typical conditions for the final week of May in this region, when multiple fisheries briefly overlap before summer heat concentrates the bite into early-morning and late-evening windows.
