Each Spring, the Brookville Tailwater is stocked with rainbow trout (from the IDNR) and brown trout. It is important to note the special regulations regarding these two species in Indiana. Rainbow trout may be kept (maximum of 5 no less than 7 inches in size). Brown trout may only be kept if they are over 18 inches and only one fish of that size may be kept per day. All other trout must be released unharmed. See the IDNR website for more information
In addition to rainbow and brown trout, smallmouth bass are found in the tailwater as well as a variety of other warm water species such as carp, suckers, sunfish, and rock bass.
