Water & Bodygrip Sets for Beaver

The beaver has been at the pond dam again — a six-inch gap in the center, water running through, fence posts on the far bank gnawed flat. You’ve got a #330 Conibear, a setting tool, and SC regulations that say water sets only, no bait. Where exactly does the trap go, how do you secure it so the beaver doesn’t push it aside, and how do you get a clean kill instead of a near-miss? This lesson builds that set from start to finish.

Sizing the bodygrip for beaver

Beaver are large rodents. An adult SC beaver averages 35–50 pounds and has a body diameter of roughly 8–12 inches when swimming. The trap size must match:

• #280 (10x9 inch frame): on the small end for a full-size beaver, but functional in narrow runs where a #330 won’t sit properly.
• #330 (10x10 inch frame): the standard beaver trap. Large enough to catch cleanly across the body; the kill bars deliver force across the shoulders and neck for a quick dispatch.
• #220 (7x7 inch frame): more appropriate for muskrat, mink, and otter, but too small for most beaver.

Set type 1: Run set in an underwater channel

A beaver run is a worn underwater trail between the lodge and feeding areas. The beaver uses it repeatedly, which makes it the most reliable blind-set location.

How to find the run: Wade the pond edge or scan from the bank. Look for a smooth channel in the bottom vegetation, 8–15 inches wide, with no debris fouling it. Muddy water close to the bank is a fresh-use sign.

Building the set:

1. Stand your #330 vertically in the run, frame facing the direction of travel.
2. The bottom of the frame should rest on the bottom or be elevated slightly so the center of the frame is at the beaver’s body level (roughly 6–10 inches below surface in most SC runs).
3. Secure the trap with two stout stakes driven into the bottom on each side of the frame, with wire or chain connecting stake to trap ring.
4. Add “leads” — two sticks or branches pressed into the bottom on each side of the trap’s approach to guide the beaver through the frame rather than around it.
5. Apply 3–5 drops of beaver castor (gland lure) to a stick or piece of bark positioned 6–8 inches behind the trap — this draws the beaver through the frame toward the lure.

Set type 2: Dam crossing (trough or breach)

Beaver regularly cross their own dam — especially at a gap or trough where water flows through. These crossings are predictable and produce fast catches.

Identifying the crossing: Look for a depression in the dam top, a chewed gap, or a section where water drains through. Active crossings often have muddy, disturbed material on both sides.

Building the set:

1. Identify the center of the trough or gap.
2. Place the #330 vertically in the trough, frame centered in the flow line.
3. Use large, stout sticks driven vertically on both sides of the frame to pin it against the trough walls — the beaver cannot displace a properly braced trap.
4. If water is deeper than the top of the frame, place a “dive stick” (a horizontal branch) near the water surface just upstream so the beaver dives beneath it and through the frame opening.
5. Castor on a stick behind the trap, as in the run set.

The why Why does the dam crossing catch so reliably?

Beaver use their dam crossings more frequently than any other location except the lodge entrance, often multiple times per night. The crossing is also partially above water, which makes the trap easier to locate and secure than a fully submerged run. The trough or gap creates a natural funnel that channels the animal through the trap opening without guides. Experienced beaver trappers often start with the dam crossing before prospecting for runs.

Set type 3: Slide set

A bank slide is a worn chute where beaver pull themselves from the water onto land, usually worn smooth by repeated use. The slide set intercepts the animal at the transition point.

Building the set:

1. At the base of the slide, where the chute enters the water, set the #330 with the frame facing into the slide.
2. The trap should be positioned so a beaver using the slide enters the frame at body level.
3. Secure both sides with stakes; the animal’s body weight on the slide holds the frame in place during triggering.
4. Castor on a stick placed at the top of the slide directs the approach.

Set type 4: Submersion foothold set

A large foothold (#4 or #5, within the 7.25-inch water-set jaw-spread limit) rigged with a drowning rig (a sliding lock on the chain that allows the animal to dive but not return to the surface) is a traditional beaver set.

• Set the foothold on a beaver trail near the water edge or at the base of a feeding area, with a drowning wire running straight out into water at least 3 feet deep.
• The chain ring slides down a wire or rod anchored in deep water; once the beaver dives, it cannot return and is held submerged.
• SC requires bodygrip and submersion sets to be checked every 48 hours (versus daily for footholds). Verify current check-interval rules with SCDNR regulations.

Set type 5: Cable restraint (snare) in a water run

SC permits cable restraints in water sets only. A properly sized cable loop in an active beaver run or trail is a legal and effective option.

• Loop diameter: 8–10 inches for beaver neck/body restraint.
• Position the loop vertically in the run, centered at body height.
• Anchor the restraint cable to a stake or tree root.
• Cable restraints hold the animal alive — you must be prepared to dispatch humanely at check time.

The dam crossing: decision point

Decision

You're at a beaver dam with a 10-inch trough in the center where water is flowing through. You have a #330 Conibear and a setting tool. How do you position the trap in the trough?

Lay the trap flat in the trough bottom so the beaver steps on the triggers Stand the trap vertically in the trough, secured by sticks on both sides Set the trap at the pond surface entrance to the trough, not inside it

Build the right set

Submersion sets must be checked once every 48 hours (not daily) The drowning wire must angle into water at least deep enough that the animal cannot surface Food bait can be used with the foothold portion of a submersion set since it's not a bodygrip trap

• ⚠ Safety Confirm setting tool and safety clips in hand before touching a #330.
• Match trap size to the run or crossing: #330 for standard adult beaver, #280 for narrow runs.
• Identify the highest-traffic location: active dam crossing, main run, or well-used slide.
• Position bodygrip trap vertically — frame aligned with the animal's swimming body plane.
• ⚠ Safety Drive stakes or stout sticks on both sides of the frame before releasing safety clips.
• Add guide sticks to prevent the beaver from going around the frame.
• Apply beaver castor (gland lure) only — no food bait at any bodygrip set.
• Confirm trap tag (name/address or SCDNR Customer ID) is attached.
• Set a reminder for the legal check interval — 48 hours for bodygrip/submersion sets.
