I lived in Batesville for several years.
Below lock 1. you will find largemouth, and kentucky bass, crappie, even some large very large stripers lots of catfish.
Between 1 and 2, there is an island that has produced some huge walleye one was 19lbs 1 ounce for a preacher in Searcy.
Lots of nice bluegill too.
Above 2 and 3 you will find smallmouths.
Trout are iffy but maybe be ok that early in the year, but if you want trout go up to Mt View and up river.
But crappie are often over looked in the river.
Depths run about 15 feet to a depth of 30-35 near the dams, we did some rescue/recovery dive training some years back.
