28-acre lake in Custer County, Montana. The lake tops out around 10 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 28 acres wrapped in 0.8 miles of bank. At index 1 the outline is almost a bowl — read the depth changes, not the shoreline. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 0.3 mi end to end and 0.2 mi across at its widest. Custer County claims this one. Castle Rock Reservoir sits 51 mi southwest — the closest neighbouring chart.
Spring rainbow trout on Spotted Eagle Lake hold shallow, usually 3 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 2 to 10 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 10 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.

When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 3 to 10 ft, and by winter most fish are in 3 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in winter. 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 | Shallow bay flat (1 ft) | 1/16 oz jig + tube, Curly-tail grub |

In spring, walleye run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Deep basin is the standout, a deep basin at roughly 10 ft, rated prime for winter 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.

Start shallow in spring: goldeye sit in 3 to 10 ft that time of year. They don't go far with the seasons — 2 to 10 ft covers summer, 3 to 10 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 10 ft range, prime in winter. Fish it in the evening and early morning and you'll meet the bite. Throw a small spinner or a dry flies / foam hoppers at dusk until the fish tell you otherwise.
