Summer Low Water Pushes Delaware Bass and Catfish into Deep Holes

What's biting

What's next

Looking ahead through the first days of July, the dominant story on Delaware's Christina and Nanticoke systems will be managing the persistent low-flow drought pattern. With USGS gauge 01493500 at 2.1 cfs, water levels are dramatically compressed, concentrating fish in predictable locations while increasing their exposure to pressure and thermal stress in shallow stretches. Any meaningful rainfall in the watershed would be the single biggest game-changer — even an inch could revive feeding windows and spread fish across a broader range of structure.

**Bass:** JB Kasper's freshwater column in The Fisherman — NJ/DE Freshwater laid out the most actionable framework: topwater early and late when shadows are on the water, transitioning to deeper structural presentations through the midday heat. On the Christina and Nanticoke, that means dawn sessions working poppers or walk-the-dog surface lures near fallen timber and bridge pilings, then a midday switch to drop-shot or Carolina-rigged plastics in the deepest available ledges and eddies. Old School Outdoors (The Fisherman — NJ/DE Freshwater) noted that heavy vegetation growth is a feature of this season — largemouth will be pushing to remaining green edges and pockets as summer heat peaks, and that pattern should hold through early July.

**Catfish:** The most reliable bite in play right now. Old School Outdoors confirmed catfishing has been "good in the river," and with flow stacked up in the deepest pools, channel cats should remain concentrated and catchable on cut bait or chicken liver fished tight to the bottom in eddy pockets below bridge crossings and river bends.

**Smallmouth Bass:** Old School Outdoors projects smallmouth will improve through July. Low, clear water rewards finesse — small tubes, ned rigs, and drop-shot in deeper pools and below current breaks are the right call. Target the same structural pockets holding catfish but fish higher in the water column during active dawn and dusk windows.

The Full Moon on June 28 adds a useful timing layer. Solunar peaks — roughly an hour before and after moonrise and moonset — tend to energize freshwater feeding even in summer heat. Pre-dawn lunar windows over the next several days are worth planning around, particularly for bass on the lower tidal freshwater reaches of the Nanticoke. Any rainfall event remains the real catalyst: JB Kasper noted July is when anglers hope for stable summer conditions, and if rain cooperates, expect catfish especially to go on a feeding run as nutrients flush into the system and dissolved oxygen recovers.

Context

Late June and early July on Delaware's freshwater rivers — the Christina, Nanticoke, and their tributaries — typically marks the onset of the reliable warm-water summer pattern. Catfish, largemouth bass, and white perch are the workhorses of these systems; smallmouth populate the cleaner, rockier upper reaches. Under normal conditions at this time of year, post-runoff flows have stabilized, water temps climb into the upper 70s on shallow stretches, and bass settle into predictable structure-oriented summer habits with topwater action in morning and evening bookends.

The 2026 season has deviated from that script. JB Kasper (The Fisherman — NJ/DE Freshwater) summarized June as "an interesting month" shaped by extremes: 90-plus-degree air temps alternating with lows in the 50s, unreliable forecasting, drought conditions, and below-normal water temperatures relative to the heat. The 2.1 cfs reading from USGS gauge 01493500 represents dramatically compressed flow for late June, a level that concentrates habitat and can elevate thermal stress on fish in the shallowest reaches.

That said, low water is not uniformly bad news for these systems. Catfish tolerate warm, low-flow conditions well and actually become easier to locate when concentrated in deep pools. Smallmouth, per Old School Outdoors (The Fisherman — NJ/DE Freshwater), are fishing well under these conditions — a signal that the fishery is holding up despite the drought. Low, clear water also rewards technical anglers willing to downsize presentations and read structure carefully.

What is notably absent from the current picture is direct reporting from tackle shops or guides operating specifically on the Christina or Nanticoke. The closest corroborating intel comes from regional freshwater contributors to The Fisherman covering the broader NJ/DE corridor, whose described conditions — drought, low water, catfish in the holes, bass best early and late — almost certainly mirror what Delaware anglers are experiencing. A return to more typical summer rainfall patterns would refresh both systems quickly and open up broader fishing opportunities across their tidal and non-tidal reaches.
