169-acre lake near Otter Tail County. The lake tops out around 18 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Minnesota DNR survey of 1971, a decades-old survey (the DNR's original lake-survey map). What the data behind the map says about each species, season by season:
On the chart, Round draws 169 acres inside 2 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 50% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.7 mi end to end and 0.6 mi across at its widest. You'll find it in Otter Tail County. The nearest mapped water is Pine, 1 mi to the southeast.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 18 ft. If you only fish one area, make it Shoreline break: a drop-off around 5 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
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 | Shoreline break (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 18 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Shoreline break (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 18 ft chart-limited; documented 12 to 40 ft | dusk & night | Shoreline break (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 18 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 5 to 18 ft game here, winter a 5 to 18 ft one. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

| Winter | 5 to 18 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates good for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 18 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shoreline break (5 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline break (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shoreline break (5 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Shoreline break, a drop-off in the 5 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |

| Winter | 5 to 18 ft chart-limited; documented 15 to 35 ft | midday | Shoreline break (5 ft) | Blade bait, Jigging spoon |
Spring rock bass on Round hold shallow, usually 2 to 10 ft. They move out to 5 to 18 ft in summer and finish the year down in 5 to 18 ft. Put Shoreline break first on the milk run — a drop-off near 5 ft that grades prime for fall. The feeding windows run the evening. The summer box starts with a ned rig (small) or a marabou jig.

The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for crappie in winter. Plan around early morning and the evening in the warm months. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
