808.8-acre reservoir near Stillwater. The lake tops out around 55 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 847 acres wrapped in 18.1 miles of bank. A development index of 4.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 44% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 3.5 mi, about 1.7 mi across. Osage County claims this one. Its nearest charted neighbour, Pawhuska Lake, is 4 mi to the south.
Spring largemouth bass on Bluestem Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 15 to 35 ft.

The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
