Hatch outlook

Fall shiner runActive window

Typical here: Sep 1 – Oct 31 · colder nights and shortening days start the push in early September — shiners slide out of open water toward warmer shallows and run up the rivers; the Rainy River run off Lake of the Woods is the marquee version

adultdaylight for the jig bite; after dark the shiners stack under dock lights with walleyes and pike mixed right in — follow the bait, not the spot — millions of shiners move together and the predators ride with them; silver profile and flash matter

Concentrates hard but travels — the school (and the walleyes under it) can be off a river mouth one week and miles upriver the next.

Jig-and-minnow is the event's signature — a frozen emerald shiner on a 1/4 oz jig drifted along the run; silver jerkbaits and trolled crankbaits take the roaming fish; blade baits under the schools.

The event happens over river mouths and the first miles upriver, warming shallow shorelines, and rocky points where the displaced bait stacks

Fall frog migrationActive window

Typical here: Sep 25 – Nov 10 · frogs leave the marshes and sloughs for deeper wintering water as fall cools — the corroborated core is October; the funnels are the connections between marsh and main lake

adultevenings into after dark, where the marsh meets the lake — a funnel event — frogs cross from marshy shallows into the larger, deeper neighboring water and burrow into the soft bottom; fish the crossing, not the marsh

A short, place-specific buffet: predators stage where the frog traffic crosses — inlet mouths, culverts, the marsh-to-lake throat.

A weedless hollow-body frog worked slow across the marsh mouth at dusk; after dark, a slow-rolled swimbait or a bottom rig fished right on the soft bottom off the opening.

The event happens over the throats between marshes and the main lake — inlet mouths, culvert channels, soft-bottom bays just off the weeds

Fishing Coldwater Lake: what the data says

1,580-acre lake near Coldwater. The lake tops out around 90 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.

Coldwater Lake maps at 1,602 acres behind 14.1 miles of shoreline. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 48% of the surface — that's where the groceries are. Figure 3 mi of water from one end to the other, 1.9 mi at the beam. Branch County claims this one. Its nearest charted neighbour, East Long Lake, is 2 mi to the north.

Largemouth Bass fishing at Coldwater Lake

Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Start at Back-bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	dawn & dusk	Back-bay flat (2 ft)	Spinnerbait, Chatterbait
Summer	8 to 20 ft	dawn & dusk	Shallow bay flat (15 ft)	Texas-rigged 10" worm, Deep-diving crankbait
Fall	4 to 15 ft	midday & dawn	Secondary point (6 ft)	Squarebill crankbait (shad), Spinnerbait
Winter	15 to 35 ft	midday	Break off the point (15 ft)	Blade bait, Jigging spoon

Bluegill fishing at Coldwater Lake

Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 10 to 25 ft. If you only fish one area, make it Back-bay flat: a weed flat around 2 ft that scores prime in spring. Best bite is early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 6 ft	midday & dusk	Back-bay flat (2 ft)	1/32 oz jig + micro plastic, Tiny popper (evenings)
Summer	4 to 15 ft	dawn & dusk	Shallow bay flat (15 ft)	Small sponge spider (fly), Micro tube jig
Fall	6 to 18 ft	midday	Shallow bay flat (15 ft)	Micro jig + waxworm, Small spoon tipped
Winter	10 to 25 ft	midday	Shallow bay flat (15 ft)	Tungsten ice jig + plastic, Tiny spoon

Crappie fishing at Coldwater Lake

When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 10 to 25 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Back-bay flat: a weed flat around 2 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 8 ft	midday & dawn	Back-bay flat (2 ft)	1/16 oz jig + tube, Curly-tail grub

Winter	15 to 35 ft	midday	Break off the point (15 ft)	Tungsten jig + soft plastic, Tiny jigging spoon

Walleye fishing at Coldwater Lake

In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	4 to 15 ft	dusk & dawn	Secondary point (6 ft)	1/8 oz jig + minnow, Hair jig
Summer	15 to 35 ft	dusk & dawn	Break off the point (15 ft)	Crawler harness on bottom bouncer, Deep crankbait (trolled)

Top water on the chart: Break off the point, a drop-off in the 15 ft range, prime in summer. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

Spring	3 to 12 ft	midday & dawn	Back-bay flat (2 ft)	Small jig + curly tail, Perch-pattern micro crank
