Fishing Colliford Lake: what the data says
934-acre lake near Cornwall. The lake tops out around 44 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Colliford Lake runs 932 acres with 12.6 miles of edge. A development index of 3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 33% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Brown Trout fishing at Colliford Lake
Spring brown trout on Colliford Lake hold shallow, usually 3 to 25 ft. They move out to 13 to 44 ft in summer and finish the year down in 5 to 35 ft. Put Deep basin first on the milk run — a deep basin near 37 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (11 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 13 to 44 ft | night & dawn | Deep basin (37 ft) | Spoon at the thermocline, Deep stickbait (night) |

| Winter | 5 to 35 ft | dawn | Deep basin (37 ft) | Jigging spoon, Small stickbait (slow) |
European Perch fishing at Colliford Lake
In spring, european perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 12 to 33 ft for winter. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 5 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | Shallow bay flat (5 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | Deep basin (37 ft) | Jigging spoon (small), Drop-shot on deep flats |

Northern Pike fishing at Colliford Lake
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |

| Winter | 5 to 15 ft | midday | Shallow bay flat (5 ft) | Tip-ups, Large jigging spoon |
Arctic Char fishing at Colliford Lake
Come spring, look for arctic char tight to the bank in 4 to 15 ft. Expect a summer slide to 13 to 44 ft, then a winter hold in 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 37 ft of water and rates prime come summer. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 13 to 44 ft | dawn | Deep basin (37 ft) | Jigging spoon vertical, Tube jig (smelt) |
