537-acre lake in Rainy River District, Ontario. The lake tops out around 23 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
Weld Lake maps at 542 acres behind 15.4 miles of shoreline, with 4 islands in the mix. An index of 4.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 90% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 3.5 mi, about 0.7 mi across. It sits in Rainy River District. Its nearest charted neighbour, Slender Lake, is 1 mi to the north.
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 7 to 23 ft before dropping to 7 to 23 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 10 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 7 to 23 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (10 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 7 to 23 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (10 ft) | Jigging rap, Jig + big minnow |
| Winter | 7 to 23 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 7 to 23 ft before dropping to 7 to 23 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 23 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for muskellunge tight to the bank in 3 to 12 ft. Expect a summer slide to 7 to 23 ft, then a winter hold in 7 to 23 ft. Start at Break off the point. It's a drop-off holding about 10 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 7 to 23 ft chart-limited; documented 8 to 25 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |

| Winter | 7 to 23 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (20 ft) | Large rubber, crawled slow |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 7 to 23 ft game here, winter a 7 to 23 ft one. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.

| Winter | 7 to 23 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (10 ft) | Blade bait, Hair jig |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 7 to 23 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
