2,898.4-acre reservoir near Jay. The lake tops out around 80 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. Species by species, here's what the data says the year looks like.
On the chart, Lake Eucha draws 2,439 acres inside 40.5 miles of shoreline — one island included. With a shoreline index of 5.9, this water is all arms and coves — edge habitat well beyond its acreage. 33% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 7.9 mi with a 2.3-mi widest point. The water lies in Delaware County. Closest neighbour on DepthScout: Spavinaw Lake, 8 mi west of here.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

Spring puts crappie in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 10 to 25 ft, wintering in 15 to 35 ft. Spring crappie concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
