Rating depth structure for largemouth bass.

710-acre lake near Weld County. The lake tops out around 26 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Banner Lakes #11 runs 648 acres with 6.3 miles of edge. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. About 79% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 2.1 mi end to end and 1.1 mi across at its widest. The water lies in Adams County. Closest neighbour on DepthScout: Hunters Glen Lake, 21 mi west of here.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 8 to 26 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
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 | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (12 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 26 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (12 ft) | Blade bait, Jigging spoon |
In spring, common carp run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 8 to 26 ft for winter. Spring common carp concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite.

| Winter | 8 to 26 ft chart-limited; documented 10 to 30 ft | midday | Deep basin (22 ft) |
Start shallow in spring: channel catfish sit in 3 to 12 ft that time of year. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 8 to 26 ft. The spot to know is Deep basin, a deep basin in about 22 ft of water that rates prime for channel catfish in winter. Warm-month bites cluster around after dark and the evening.

| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | |
| Summer | 8 to 25 ft | night & dusk | Deep basin (22 ft) | |

| Winter | 8 to 26 ft chart-limited; documented 20 to 40 ft | midday | Deep basin (22 ft) |
The spring pattern is a shallow one: crappie in 2 to 8 ft. As the season builds they drop to 10 to 25 ft, wintering in 8 to 26 ft. Top water on the chart: Deep basin, a deep basin in the 22 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (12 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (12 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 26 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (22 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. As the season builds they drop to 4 to 15 ft, wintering in 10 to 25 ft. Spring bluegill concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (12 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (22 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for black bullhead tight to the bank in 2 to 9 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 8 to 26 ft. Start at Deep basin. It's a deep basin holding about 22 ft of water and rates prime come winter. Prime time lands in after dark and the evening.
