Three Things to Know | 2026 Shad Run
East Coast Shad Tracker : Mapping the 2026 "Biological Wave"
Shad don't just swim upriver; they move in a massive biological wave that hits specific "gateways" at specific times.
We’ve mapped the 2026 wave from Virginia to New England. Use the tracker below to see which gateway is opening this week, but remember: the fish are moving faster than the news. Grab your shad darts and read more about presentation to help you find and land some of these great river fighters, and then find the stripers that follow.
Thermal Pulse Triggers : Decoding the "Migration Switch" for 2026
A 2-degree jump in water temperature is the difference between an empty river and a "wall" of fish.
Knowing the temperature is easy; knowing how that temperature changes the depth of the strike is the "Science of the Strike." We’ve broken down the 2026 thermal pulse requirements for both Hickory and American shad.
Predator Interception : Mastering the "Shad-to-Striper" Transition
Striped bass aren't just following the shad; they are actively "staging" at specific river bottlenecks.
If you are fishing where the shad are spawning, you are too late. The big stripers are waiting at the "Interception Zones" we’ve identified below.
Striped bass have been shown to selectively target river herring and shad during their spawning runs, positioning themselves downstream of spawning aggregations and feeding most actively at night and during ebb tides.
Why Striped Bass Follow the Shad : The Science of the Strike
Striped bass are opportunistic predators but they are not random. In spring tidal rivers, their position is almost always tied to the position of forage fish — and shad and river herring are the dominant forage.
Research on the feeding ecology of striped bass confirms they are a highly mobile and generalist predator that feeds heavily on clupeids including American shad, blueback herring, and alewife during their spring and summer feeding migrations.

The mechanism is simple: shad move into rivers to spawn and are vulnerable. They are stacked in predictable locations — below dams, in eddies behind boulders, at the mouths of tributary creeks, along channel edges.
Striped bass position themselves downstream of spawning aggregations and exhibit strong feeding activity during ebb tides when herring and shad are forced to mill and stage rather than continue moving upstream.
Find where the shad are stalling and you have found where the stripers are eating.
The shad run also tells you something about the size of stripers you will encounter. The predator-prey interaction between striped bass and blueback herring during spring river migrations is predator size dependent — blueback herring are most commonly found in the stomachs of striped bass between 650 and 999mm total length, meaning the largest fish in the river are the ones eating shad most aggressively. If the shad run is on, the biggest stripers in the system are somewhere nearby.
Hickory vs. American Shad : Finding the Striper 'Push' in Tidal Rivers
Two species of shad run East Coast tidal rivers every spring and they matter differently to the angler.
Understanding which species is running — and when — tells you where to fish, what stage the forage wave is in, and how close the big striper push is.

HICKORY SHAD
Hickory shad are smaller, more aggressive, and arrive first. Hickory shad are anadromous fish that spend most of their lives at sea and enter freshwater only in the spring to spawn, ascending rivers in runs that may cover hundreds of miles. They typically spawn at night in shallow water with a rocky bottom when water temperatures are between 58°F and 62°F. On the Roanoke River in North Carolina, hickories appear in the lower river near Plymouth as early as late February. On the James and Rappahannock in Virginia, they typically show in early to mid-March. Hickories fight hard for their size and are sometimes called the poor man's tarpon for their aerial acrobatics when hooked.
AMERICAN SHAD:
American shad are larger, arrive after the hickories, and represent the peak of the forage wave. American shad begin their spawning runs when water temperatures reach approximately 50°F, with peak activity around 65°F. A single female American shad releases 100,000 to 600,000 eggs in a spawning season in multiple batches, making them one of the most prolific spawners in East Coast rivers. When American shad are running in numbers, the striper bite typically hits its peak — the forage wave is at its densest, the river is full of protein, and big stripers are actively feeding rather than just staging.
REGULATIONS: PAY ATTENTION
There is an important regulatory note on American shad. A statewide moratorium on keeping American shad is in effect in Virginia — they are catch and release only. Check your state's current regulations before keeping any shad. River herring including alewife and blueback herring are similarly protected in many states. Always verify current shad and herring regulations at your state fisheries agency before you fish.
What Water Temperatures Trigger the Spring Shad Run?
UPDATED APRIL 18 2026: The shad run moves north as spring moves north. Water temperature is the trigger. Fish start moving when water temperatures hit 50°F. The table below shows expected peak timing for each major tidal river system, current water temperatures, and which species to expect.
Hickory shad arrive first in every river, followed by American shad 1 to 2 weeks later. Stripers feeding on shad typically concentrate during and just after the American shad peak.

Striper Staging Zones : Navigating the "Current Seams" of Tidal Rivers
In high-flow spring rivers, predators hide in the "seams" to save energy while they hunt.
Most anglers cast into the fastest water. The pros cast into the "Dead Water" pockets where stripers wait for the shad to be delivered to them.
Understanding the shad's movement patterns inside the river tells you exactly where to put your bait.
Active Hunting Tip: Striped bass don't swim with the shad; they swim under them. In high-flow rivers like the James, use a rig that suspends your bait in the lower third of the water column. If you are fishing too high, you’ll catch shad. If you fish lower, you’ll find the stripers.
Understanding Shad Movement During Run ▼
The most reliable striper holding spots during the shad run are below any dam or obstruction that stops or slows the shad migration. At Fletcher's Cove on the Potomac, shad stack up inside the cove during moving tides as they stage their continued progress upriver to spawn — and stripers position just downstream to intercept them. The same pattern repeats at every obstruction on every shad river from Virginia to New England. Find the first dam on a river, and you have found the most predictable striper feeding station of the spring.
LOOK FOR THE SEAMS
Below dams, look for the seam where fast water meets slow water. Shad hold in slower water and rest, then dart into faster current to continue their push upstream. Stripers sit in the faster water at the edge of the seam and pick off shad as they cross. The inside of river bends, the mouths of tributary creeks, and the downstream side of large rocks and boulders all create these seams. In tidal rivers, incoming tides push shad upriver while outgoing tides can stall their progress — shad will often take a quick breather in calmer pockets before tackling the next stretch of moving water, concentrating in eddies, the outside of bends, creek mouths, and places where rivers widen.
TIME OF DAY MATTERS
Tide and time of day matter more than most anglers realize during the shad run.
Research on striped bass feeding activity during the shad and herring run found that stripers were most active at night and during ebb tides — during peak outflow periods, herring and shad milled downstream of obstructions in scour pools, and stripers fed most aggressively during these stalling events.
Fish the last two hours of the outgoing tide and the first two hours of the incoming tide for the most consistent action.
For a deeper look at how striped bass use current, structure, and their lateral line to hunt in tidal rivers during the spring run, see our complete guide to catching stripers in high-flow rivers.

How striped bass use scent, vibration, and sight to hunt in tidal current
The Physics of the Drift : Calibrating Your Rig for the "Lower Third"
The most effective approach during the shad run is to put your bait in the water column where both shad and stripers are actively moving — not on the bottom.
Shad travel through the mid-water column as they migrate upstream. Stripers hunt them there. A bait or lure suspended and drifting in the current at mid-depth is the most natural presentation you can make during this specific window.

FOR STRIPERS: DRIFT YOUR BAIT
For stripers specifically, large shad or herring on a drift rig suspended at 3 to 6 feet off the bottom is the classic tidal river spring presentation. The bait needs to drift naturally with the current in the same lane the shad are using. Anchoring and casting across current works, but drifting a bait through the seam where fast and slow water meet — the exact lane the migrating shad are using — is consistently more effective because the presentation matches the natural movement of the forage.
Research on striper feeding behavior confirms they orient upward and attack prey silhouetted against available light — a bait resting on the bottom sits outside their primary hunting window. The most effective presentation during the shad run positions bait at mid-depth in the current, drifting naturally at the same speed as the migrating forage. This intersection of depth, drift speed, and scent dispersal is what triggers the strike. Drift rigs designed to suspend and elevate bait in moving water — keeping it off the bottom and in the active scent and vibration cone — are the mechanical solution to this biological requirement.
The mechanical requirements of this presentation are specific: the rig needs to generate lift to keep bait elevated off the bottom, drift at current speed without spinning or dragging, carry a circle hook to comply with mandatory tidal river regulations, and use non-toxic terminal tackle in compliance with the growing restrictions on lead sinkers in sensitive spawning habitat. Drift rigs engineered for suspended bait presentation in moving water check all of these boxes — and the presentation difference between a bait drifting at mid-depth versus one sitting on the bottom can be the difference between a fish that detects your offering and one that swims past it entirely.
LURES FOR SHAD:
Surprisingly, there is no controlled research on shad dart color preference. Here's what decades of angler experience tells us — and here's what we actually know from shad biology that gives these color choices a biological basis.For shad themselves, small darts and spoons fished on light spinning gear in the 6 to 10 pound test range are the standard presentation. Cast upstream or straight across the current, let the lure sink for a second, then start a slow retrieve — shad tend to travel low in the water column and if your lure is riding too high you are probably fishing over their heads.
Hickory shad will often hit on the swing as the lure turns in the current. American shad sometimes require a slower presentation.
Tactical Visibility: Choosing a Shad Dart Color for the Striper Push
Most anglers think shad dart color is about what the fish "likes." It isn't. It's about Hydrodynamic Visibility. In the churning, muddy spring water of the James or the Potomac, the fish needs to see the forage before it can strike.
- Fluorescent Pink & Chartreuse: Best for "High Turbidity" (muddy water). These colors create a sharp silhouette in low-visibility current seams.
- White & Silver: Best for "Low Light" (dawn/dusk). These mimic the natural flash of a river herring or a juvenile shad.
The Pro Move: Catching "Live Forage" for Big Stripers
If you want to catch the 40-pounders, you need a fresh, local snack. Use a 1/8oz dart to catch a legal hickory shad (check your local regulations first!), and then immediately transition to a FATKAT Drift Rig.
By suspending a fresh bait off the bottom in a current seam, you aren't just fishing; you are matching the exact biological behavior of a stunned shad being swept toward a waiting predator.
The Color Framework That Actually Works — Backed by Biology and Angler Experience ▼
What the biology tells us:
Shad, like most fish, detect lures through contrast against the background light. In the turbid, stained spring water that characterizes most tidal river shad runs, high-visibility colors create more contrast against a murky background than natural or subtle colors do. This is the biological basis for why fluorescent colors dominate the shad dart color conversation — not because shad prefer pink or chartreuse, but because those colors are simply more visible in low-clarity conditions.
Water clarity should drive your color selection more than anything else:
- Turbid/stained water: Chartreuse, hot pink, orange. Maximum contrast colors. These are your starting point in most spring tidal river conditions.
- Moderately clear water: Red and white, green and white. The original combination — still deadly on rivers like the Rappahannock.
- Clear water or bright sun: Silver, white, natural. Lower contrast but more natural profile.
What decades of angler experience tells us:
Every experienced shad angler agrees on one thing — shad are notoriously fickle. The color that produced fish at 8am may be ignored by 10am. The dart that worked Saturday may not produce a single strike Sunday. This isn't inconsistency in the angler — it's a real behavioral characteristic of spawning shad that even experienced guides acknowledge they can't fully explain.
The underrated variable — action and depth:
Color gets all the attention but action may matter more. American shad are exceptionally sensitive to vibration and water movement — their otoliths, swim bladder structure, and lateral line canal system make them among the most vibration-sensitive fish in the river. A dart worked at the wrong depth or wrong retrieve speed will get ignored regardless of color. Before changing color, try:
- Changing retrieve speed (slow roll vs. lift-and-drop vs. steady)
- Changing depth (shad school in tight bands — 6 inches can matter)
- Changing dart size (smaller darts for deeper fish, larger for surface action)
The one rule that overrides everything:
Position beats color every time. A chartreuse dart drifted through the middle of a shad school at the right depth and right retrieve speed will out-fish a perfect color choice presented 3 feet above or below the fish. Find the school first. Then work the color rotation.
The Virginia DWR Shad Cam — The Best Free Tool for Timing Your Trip
The Virginia Department of Wildlife Resources runs a live underwater camera at Bosher's Dam on the James River. You can watch shad, stripers, blue catfish, lamprey and other species passing through the fish passageway in real time as the spring run unfolds.
It is one of the best free tools available for timing a trip to the James River — when you see thick schools of shad stacking at Bosher's Dam, stripers are feeding heavily in the river below it. Check the camera here at Virginia DWR's shad cam page. The camera runs live during the spring migration season and is updated throughout the day.
Next Best Tool: Proper Bait Presentation ▼
Effective Bait Presentation
The most effective presentation during the shad run positions bait at mid-depth in the current lane, drifting naturally at the same speed and depth as the migrating shad. This requires a rig that generates enough lift to suspend the bait off the bottom while maintaining a natural, drag-free drift through the strike zone. Drift rigs with elevated bait positions accomplish this by using the current itself as the presentation mechanism — the rig does not fight the water, it uses it.
Regulations — What You Can Keep During the Shad Run
Before you keep anything during the shad run, check current regulations for both shad and stripers. American shad have a statewide catch and release moratorium in Virginia — you cannot keep them. River herring including alewife and blueback herring are subject to strict limits or full moratoria in most states.
Always check your state fisheries agency for the current shad and river herring rules before you fish.
Circle Hook Regulations
Protect the Ecology: Remember, circle hooks are now the law when using natural bait for stripers. Using a sustainable, lead-free setup doesn't just keep you legal—it protects the river for the next generation of shad. Master the Biology. Protect the Ecology.
Understanding Striped Bass Regulations ▼
For striped bass, the shad run window overlaps almost exactly with the spring catch and release period in the states where the shad run is most active. In Virginia, harvest does not open until May 16. On the tidal Potomac, harvest opens May 15. In Maryland, harvest opens May 16 on the Bay main stem.
See our page on Striped Bass Regulations for Tidal Waters->
This means that right now, catching a striper eating shad is catch and release fishing in the most important rivers. That is actually good news — the fish are aggressive, stacked, and feeding hard, and the fishing can be extraordinary even when you are releasing everything. Before the harvest window opens in your state, check the full 2026 tidal river striped bass season dates and regulations for your state.
Frequently Asked Questions About the Shad Run and Striped Bass
The hickory shad run on the James River near Richmond typically starts in early to mid-March and peaks around mid-April. The Rappahannock near Fredericksburg follows a similar timeline.
In 2026, a cold winter has the run running slightly behind schedule — but as of late March the hickories are actively moving on both rivers. American shad follow the hickories by 1 to 2 weeks, typically peaking in late April on the James and Rappahannock. You can monitor real-time shad activity at Bosher's Dam on the James using the Virginia DWR shad cam.
The Bi-State Shad Fishing Contest on the Delaware River is held April 23 to 26, 2026, which gives you a reliable indicator of when the Delaware River shad run is expected to peak.
Hickory shad begin showing in the lower Delaware in late March to early April. American shad peak in late April to mid-May. The Delaware is one of the strongest shad rivers on the East Coast and the fishing along the entire river from the Delaware Water Gap south to the tidal section can be outstanding during the peak.
The Hudson River shad run typically begins in early to mid-April with hickory shad showing first. American shad peak in late April to mid-May.
The Hudson River striped bass season opens April 1 — which means the early weeks of the Hudson shad run coincide with an open striper harvest season. Remember that the Hudson uses a 23 to 28 inch slot, not the coastwide 28 to 31 inch slot. A 30 inch fish that is legal in the ocean is illegal on the Hudson. Check the 2026 tidal river striped bass season dates and regulations for New York before keeping any fish.
Yes — live or fresh dead shad and herring are among the most effective striper baits in tidal rivers during the spring run. A live hickory shad or blueback herring on a drift rig fished through the current seam below a dam or obstruction is one of the deadliest striper presentations of the year.
Important regulatory note: in many states you cannot use American shad or river herring as bait due to their protected status under state moratoria. In those states, bunker, gizzard shad, and large golden shiners are legal bait alternatives that produce a similar presentation. Always check your state's current regulations on bait use before fishing.

They do not stop feeding entirely — but the concentrated, predictable feeding frenzy ends because the forage wave disperses. During the peak shad run, shad are stacked in predictable locations and stripers know exactly where to be.
Once the spawn is complete and shad begin moving back downriver and out to the ocean, the forage distributes across the river system and stripers shift to a more nomadic feeding pattern following whatever bait is available. This post-spawn window — roughly mid-May through June depending on your river — can still produce excellent striper fishing as fish are well-fed, aggressive, and beginning to move toward their summer ocean feeding grounds.
The 2026 shad run is running slightly late compared to recent warmer years. A cold winter across the mid-Atlantic left river water temperatures 2 to 4 degrees below the five year average for late March.
Since shad migration is triggered primarily by water temperature, a cold spring delays the entire sequence by 1 to 2 weeks. This does not mean the run will be smaller or shorter — when the warming comes the shad and the stripers following them tend to push in quickly and the action can be concentrated and intense. Check water temperatures weekly using NOAA's tide station data at tidesandcurrents.noaa.gov to know when your river is approaching the trigger temperature for each species.
