Deep Water Ned Rigging for Ontario Smallmouth
, 5 min reading time
Deep-water Ned rigging for Ontario smallmouth: the weights, line, and boat positioning that keep a finesse rig fishing 15-35 feet of late-fall structure.
Most anglers treat the Ned rig as a shallow-water toy. Then October hits Ontario, the smallmouth slide off the banks into 15 to 35 feet of water, and the Ned rig quietly becomes one of the best deep presentations going. The problem is that the light-head, straight-fluoro setup that works at 8 feet falls apart at 30. Deep water Ned rigging is its own skill: heavier heads, braided line with a long leader, and boat control that keeps the bait in the strike zone long enough to matter.
Deep Water Ned Rig Weights: Matching the Head to the Depth
Depth control is the whole game. A 1/16 oz Ned head that falls at roughly one foot per second in 8 feet of water takes 25 seconds to reach 25 feet, and by then wind and current have pulled it far off your cast target. Heavier heads keep the fall time under 10 seconds and keep contact with the bait.
- 15-20 feet: 1/8 oz mushroom head. Still fishes slow enough for cold-water smallmouth.
- 20-28 feet: 3/16 oz. The most-used weight for deep Ned rigging on Lake Simcoe structure.
- 28-40 feet: 1/4 oz. Falls fast, so pause longer between moves to let fish find it.
Choose the mushroom head by head shape, not just weight. A flat mushroom head stands the bait upright on bottom, which is what gives the Ned rig its signature posture. Round ball heads roll on hard bottom and lay the bait on its side. In deep water, where you cannot see the bait, that standing posture is the difference between the rig working and it just being a grub on a hook.
Bait size matters less than most people think, but smaller is usually better when water drops under 55 degrees. The 4 inch Float Ned Worm in Algae is a reliable deep-water colour for Ontario: green-pumpkin tones match the gobies and crayfish smallmouth are eating on rock and sand transitions, and the buoyant body keeps the tail up on the head even with the heavier jig.
Line and Leader Setup for Deep Water Sensitivity
Fluorocarbon mainline is a liability at 30 feet. It stretches, it coils, and its sink rate fights the slow fall you want. The standard deep Ned rigging line setup is braided mainline to a long fluorocarbon leader.
Spool 10 lb test braid as the mainline. Braid transmits bottom contact far better than fluoro, which is how you know whether your 1/4 oz head just landed on rock, gravel, or mud. Then tie 8 to 12 feet of 6 to 8 lb fluorocarbon leader with an FG or Alberto knot. The long leader does two jobs: it keeps the visible braid away from pressured fish, and fluoro's slight give cushions the hookset on light-wire Ned hooks.
Keep the rod at 6 ft 10 in to 7 ft 2 in, medium-light power, fast tip. The extra length over a typical 6 ft 6 in finesse rod picks up slack faster, and at 30 feet there is a lot of slack between you and the bait. Match it with a 2500-size spinning reel. Drag matters more than most people budget for: smallmouth in deep water often hit on the fall and charge sideways, so set the drag light enough that 8 lb leader survives the first run.
Boat Positioning for Deep Water Ned Rigs
Deep Ned rigging is a vertical game with horizontal casts, and the boat has to cooperate. The basic pattern: position the boat downwind of the structure, engage spot lock, and cast into the wind so the bait falls back toward the boat along the bottom contour. This keeps line tension natural and the fall path predictable.
Work the structure in passes, not circles. If your electronics show a rock hump in 28 feet, set up on the deep side, make long casts onto the shallow edge, and drag the rig down the break with 6-inch pulls separated by 10 to 15 second pauses. Deep smallmouth eat on the pause far more often than on the move. When bites happen, they will usually come from the same depth contour, so once you get one, hold that depth and work it for 15 minutes before repositioning.
Wind is your biggest enemy. Over about 12 knots, a light Ned head bows the line into an arc and you lose bottom contact entirely. In that case, drop deeper on the weight scale (1/4 oz instead of 3/16 oz), shorten casts, or switch to dragging straight under the boat. There is no shame in parking on one rock pile for an hour. Deep-water smallmouth rarely roam far in cold water, and one good piece of structure can produce a full day.
When the Deep Ned Rig Is the Wrong Call
The deep Ned rig is a slow, precise tool, and there are days it will not keep up. If bass are actively chasing bait up high in the column, visible on electronics as arches off the bottom, a small swimbait on a heavier head gets to them faster. If you are fishing dense grass edges rather than open rock, a Texas-rigged stick worm punches through cleaner.
But when the smallmouth are glued to bottom in 15 to 35 feet and ignoring everything that moves fast, the Ned rig is hard to beat. For Ontario late-fall fishing, that describes most days from mid-October until the boats come out. Darker colours like the Float Ned Worm in Black show a stronger silhouette in the low light of deep water, so pack both dark and green-pumpkin and let the fish decide.
Deep water Ned rigging asks for three things: the right head weight for the depth, braid to a long fluoro leader, and boat control that keeps the bait in front of the fish. Get those right and it fishes like any other Ned rig, just with bigger rewards at the end of a longer fall.
