flows northeast: Henniker to Penacook The river tops out around 6 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Contoocook River maps at 466 acres behind 48.4 miles of shoreline. With a shoreline index of 16, this water is all arms and coves — edge habitat well beyond its acreage. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 13.8 mi with a 2.5-mi widest point. It sits in Merrimack County. Its nearest charted neighbour, ROLF POND, is 3 mi to the southwest.
Spring smallmouth bass on Contoocook River hold shallow, usually 2 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 2 to 6 ft once it turns cold. Put Riffle & run (mile 12.4) first on the milk run — a rock pile near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | dawn & dusk | Riffle & run (mile 12.4) (3 ft) | Ned rig, Tube jig |
| Summer | 2 to 6 ft | dawn & dusk | Riffle & run (mile 12.4) (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 6 ft | midday & dawn | Inside bend (mile 13.7) (4 ft) | Jerkbait, Blade bait |
| Winter | 2 to 6 ft | midday | Current seam (mile 3.7) (3 ft) | Blade bait, Hair jig |
Come spring, look for rainbow trout tight to the bank in 2 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 1 to 6 ft. Start at Current seam (mile 3.7). It's a current seam holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft | dawn & dusk | Current seam (mile 3.7) (3 ft) | Inline spinner (silver), Small spoon |
| Summer | 2 to 6 ft | dawn & dusk | Current seam (mile 3.7) (3 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 2 to 6 ft | dawn & dusk | Current seam (mile 3.7) (3 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 1 to 6 ft | dawn | Current seam (mile 3.7) (3 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: brown trout sit in 1 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 1 to 6 ft covers winter. Top water on the chart: Current seam (mile 3.7), a current seam in the 3 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | dawn & dusk | Eddy pocket (mile 2.3) (4 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

| Winter | 1 to 6 ft | dawn | Eddy pocket (mile 2.3) (4 ft) | Jigging spoon, Small stickbait (slow) |
