Summary
Westbury-on-Severn sits on the upper tidal reaches of the River Severn, where the estuary narrows and the tide still packs serious power. It’s a classic Severn-bank mark for flounder and bass, with a real chance of a winter codling in the right conditions. Expect big tides, fast flows, soft mud, and the famous Severn Bore—this is proper estuary fishing with plenty of character.
Location and Access
Access here generally means fishing from the floodbank/sea wall and firmed revetment rather than the mud flats—never leave the hard ground. You’re aiming for sections of bank between Broadoak and Westbury village on the A48, within the GL14 postcode area.
- Approach via the A48; look for signed public footpaths or Severn Way access points that lead to the floodbank across pasture. Avoid crossing private land without a public right of way.
- Parking is usually in small lay-bys or discreet roadside pull-ins along the A48 near Broadoak/Westbury (GL14). Do not block farm gates; check for local signage and restrictions.
- The walk is typically 5–15 minutes on level but often uneven, grassy floodbanks; expect livestock, mud, and seasonal bogginess.
- Terrain is rip-rap stone, grassed bank, and occasional firmed earth. There is no safe standing on the foreshore itself—keep to the bank/rock armour.
Seasons
The upper Severn estuary here offers estuarine regulars with seasonal peaks. Expect fewer species than the lower channel, but good sport when conditions align.
-
Spring (Mar–May):
- Flounder (building numbers; best on worm/crab baits)
- School bass (first fish on peeler crab as temps rise)
- Thick-lipped grey mullet (occasional in calmer, clearer spells)
-
Summer (Jun–Aug):
- Bass (schoolies with the odd better fish on crab/strip baits)
- Flounder (consistent)
- European eel (common; catch-and-release only)
- Mullet (occasional; wary fish)
-
Autumn (Sep–Nov):
- Bass (peak time; chance of a better fish on big crab/squid)
- Flounder (good numbers)
- Whiting (occasional in late autumn on bigger tides)
-
Winter (Dec–Feb):
- Codling (occasional, more likely after cold snaps and rougher weather down-channel)
- Whiting (sporadic)
-
Protected/migratory species present: shad, salmon, sea trout, lamprey, smelt—do not target; release immediately if hooked.
Methods
Estuary ledger fishing dominates, with simple, strong end tackle that copes with heavy tide and debris. Lures are niche due to turbidity and flow but can score at slack water.
- Rigs:
- Simple running ledger with 4–6 oz fixed-wire or breakout gripper leads to hold bottom.
- One-up/one-down flapper for flounder and whiting on neaps.
- Up-and-over or pulley for bass/codling with larger baits and a longer snood.
- Include a weak-link/rotten-bottom to the sinker to save gear in snags.
- Hooks and traces:
- Size 1–2 for flounder/whiting; 1/0–3/0 for bass/codling.
- 20–30 lb snoods (shorter in heavy flow; 2–3 ft for bass on neaps).
- Baits:
- Peeler crab is king in spring/summer for bass and flounder.
- Blow lug/black lug, ragworm, and cocktail baits (lug + crab, mussel + squid) work year-round.
- Squid or mackerel strip ups the codling/whiting odds in winter.
- Times/approach:
- Fish the flood and first of the ebb: roughly 2 hours either side of high water, adjusting for bore times.
- Keep rods high on a sturdy tripod to clear the flood and weed; frequently check for crabs stripping baits.
- Lure option: heavy paddle-tails or metal at slack water around HW for bass, if clarity allows.
Tides and Conditions
The Severn’s colossal tidal range and bore dictate everything. Plan sessions around bore predictions and target manageable flows.
- Tide state:
- Best around mid to high water; low-water ground is unfishable mud and channels.
- Neap tides are kinder (less flow, easier lead control) and often better for bite detection.
- Big springs stir fish movement but demand heavier leads and quick re-baiting.
- Severn Bore:
- Do not fish when a significant bore is due; the surge, undertow, and debris are hazardous.
- Fishing can switch on 30–90 minutes after a bore as the flood steadies—time it carefully from the bank.
- Conditions:
- Slight SW–W winds with settled pressure suit the upper estuary.
- After heavy rain, fresh water can push fish down-channel; give it a tide or two to recover.
- Time of day/seasonality:
- Dawn/dusk for bass; night sessions help for codling/whiting when present.
- Peak bass: late summer to mid-autumn; best flounder: spring through autumn.
Safety
Treat Westbury-on-Severn as a dynamic estuary environment with real, non-negotiable hazards. Preparation and conservative decision-making are essential.
- Soft mud: never step off the floodbank/rock armour onto the foreshore—lethal soft mud and deep gutters.
- Bore hazard: surges arrive fast; water rises rapidly with powerful undertow. Leave extra margin well before any forecast bore.
- Fast tide and debris: expect weed, logs, and flotsam on big tides; keep lines high and stay alert.
- Slips and trips: rock armour is uneven and slimy; wear cleated boots and use a stable, tall tripod.
- Edges and drop-offs: set up well back; the bank can undercut after floods.
- Lighting and PPE: headtorch at dusk/night; strongly consider a personal flotation device.
- Livestock and crops: follow marked paths, close gates, and respect farm operations.
- Accessibility: not wheelchair-friendly; uneven ground and stiles are common.
Facilities
Facilities are sparse at the water’s edge; plan to be self-sufficient. Nearby villages offer essentials along the A48 corridor.
- No toilets, shelter, or bins on the bank—pack in/out everything.
- Parking is limited to lay-bys and pull-ins; observe any local restrictions and bore-day crowding.
- Food and pubs available in Broadoak/Westbury and nearby Newnham-on-Severn.
- Tackle and bait from shops in Gloucester, Lydney, or Forest of Dean towns—ring ahead for peeler crab/black lug.
- Mobile signal is generally present along the A48 but can be patchy on low ground by the bank.
Tips
Think ‘big tide management’ and bait freshness. Small adjustments make a big difference on this river.
- Use fresh peeler crab in spring/summer; in autumn, try lug + crab or mussel + squid cocktails for bass.
- Long, streamlined baits cast and fish better in strong flow; bind with elastic to resist crab attack.
- Fixed-wire grippers hold better than breakout leads on this bank; add a weak link to save leads in snags.
- Keep trace lengths modest in heavy flow (18–24 inches); lengthen on neaps when bites are finicky.
- After a bore, give it time: start fishing once the boil settles and the flood ‘paces’ rather than rips.
- Scale your hooks to the bait, not the dream fish—size 1/0 patterns land plenty of quality bass here.
- Mark your tripod feet on the grass and step back a rod length before high water to avoid getting cut off.
- Expect ‘bait rattle’ from small eels and crabs—regularly refresh baits rather than waiting out stripped hooks.
Regulations
This is tidal water with overlapping sea and EA byelaws—know the basics before you cast. Always check the latest rules from the MMO and Environment Agency.
- No rod licence is required to fish for sea species (e.g., bass, flounder, codling). An EA rod licence is required if targeting salmon, trout, or coarse fish; close seasons apply to coarse species on rivers.
- Bass (England, 2024/25 typical rules): minimum size 42 cm; recreational daily bag limit often 2 fish per angler per day during the open season (commonly 1 Mar–30 Nov) with catch-and-release only in the closed months. Check current MMO notices before your trip.
- European eel: retention prohibited in England—catch and release only.
- Shad (twaite/allis), salmon, sea trout, lamprey, and smelt: protected/migratory—do not target; release immediately if accidentally hooked.
- Local access: many riverbank sections cross private farmland and SSSI-designated land. Use public rights of way only, heed any ‘no access’ signs, and avoid disturbing livestock and nesting birds.
- Litter and biosecurity: remove all line and bait waste; rinse and dry gear to prevent invasive species spread.
- Safety notices: bore timetables are published locally—do not ignore bore-day closures or warden advice.
