Summer bass and catfish season opens on the Christina and Nanticoke

What's biting

What's next

Looking ahead over the next few days, Delaware freshwater anglers should expect classic late-June conditions on the Christina and Nanticoke. The First Quarter moon arriving today favors feeding windows in the early morning and again in the late afternoon — a solunar alignment that lines up well with bass sliding onto tidal flats and shallow shorelines at first light before retreating to cooler structure as midday heat builds.

Without current gauge data, it is worth pulling USGS streamflow readings for both rivers before launching. Summer thunderstorms common in late June can push the Christina and Nanticoke into stained, elevated-flow conditions quickly, shifting fish off their typical haunts. If flows are running higher than normal, target slower backwater eddies, tributary mouths, and shaded coves where bass can ambush baitfish without fighting current.

Field and Stream's summer bass coverage notes that exploring less-pressured water is one of the most reliable late-June strategies — the same logic applies to the quieter creek arms and oxbow pockets off the Nanticoke's main channel, which typically hold quality largemouth undisturbed well into the heat of summer. Poppers and walking baits are effective through the weekend during the low-light hours; once the sun climbs, drop down to Texas-rigged soft plastics or finesse jigs worked along steep bank transitions.

For catfish, warming water temperatures in late June traditionally fire up night fishing on both systems. Cut bait and stink baits fished on bottom near channel structure, bridge pilings, and deeper holes are the standard approach on Delaware tidal rivers in summer. Per Wired 2 Fish, the invasive blue catfish continues to expand throughout the Chesapeake Bay watershed; check current Delaware state fishing regulations for any special harvest provisions on blue cats, as several neighboring states are actively encouraging their removal.

White perch, a tidal freshwater staple on both rivers, typically scatter to deeper channel water by late June. Small curly-tail jigs and spinners worked at mid-depth near submerged wood or channel edges will pick off perch holding tight to structure during the heat of the day. First and last light remain the most productive windows across all species this weekend.

Context

For Delaware's Christina and Nanticoke rivers, the third week of June historically marks the end of the post-spawn transition and the start of the true summer grind. Largemouth bass on both systems typically finish spawning by early to mid-June; by the solstice, fish that were catchable on or near the beds have fully dispersed into summer holding areas — shaded banks, laydown timber, dock pilings, and deeper holes where temperatures are at least marginally cooler than the sun-baked shallows.

No current USGS gauge data was available for this report, making a precise comparison to historical flow and temperature norms impossible. Under typical seasonal conditions, both rivers are usually running warm and at moderate-to-low summer flow by this date, with water temperatures often in the upper 70s Fahrenheit. If this season has tracked normal, the morning topwater bite on both systems will be brief — productive from first light until roughly an hour after sunrise — before heat shuts fish down until evening.

The blue catfish expansion story flagged by Wired 2 Fish in Maryland is useful historical context for Delaware. These non-native predators have been documented expanding through Chesapeake Bay tributaries over the past decade, and the Nanticoke in particular, as a direct Bay tributary, has seen increasing blue cat presence. Their summer behavior mirrors that of channel cats — deeper holes, night feeding — but they outcompete native white perch and other forage species, making harvest a net positive for the ecosystem.

None of the available angler-intel feeds this week carried a direct on-the-water report from a Delaware freshwater shop, guide, or state source covering the Christina or Nanticoke specifically, so this report is grounded in seasonal patterns and watershed-level context rather than fresh local testimony. Delaware's Division of Fish and Wildlife publishes periodic angler reports that are worth checking for current firsthand conditions on both systems.
