91-acre lake near Cook County. The lake tops out around 7 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Monker maps at 91 acres behind 1.7 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. It sits in Cook County. Devil Track sits 3 mi northwest — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 1 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 1 to 7 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
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 | 1 to 7 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (6 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 7 ft chart-limited; documented 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 7 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 5 features, led in depth by Main-lake point at roughly 7 ft.
