Dixie Jack sorry i didn't see your post until now.
Here's a link to some info on Indiana's trout streams
Indiana Fly Fishing :: Indiana Fly Fishing, Indiana Trout Streams and Indiana Fly Shops
and a list of the waters with trout stockings from IN DNR:
Although I've never fished in Indiana for trout or anything else, i imagine a lot of the trout stocking in streams is done in Spring on a "put and take" basis-- with many of the streams heating up too much during summer to hold trout in August (sustained water temps over 70 degrees is generally lethal to trout). The exception might be some tailwaters with cold water releases from the bottom of dams that might keep year round trout friendly temps immediately below and downstream of the dam--- for example the Brookville tailwater on the East Fork of the White River
There's also 3 year round catch and release areas in Elkhart County: the Little Elkhart River in Elkhart County, a trib of the St Joseph and Solomon Creek and Cobus Creek also in Elkhart County. The St Joseph and some nearby streams (Trail Creek, Salt Creek, East branch of Little Calumet etc) also get some steelhead, so that's worth looking into also if you're close by.
But being in IN you probably also have a lot more opportunities for smallmouth in streams and they're worth chasing with a fly rod too.
You can find more info on IN fisheries including trout, steelhead and warmwater in the DNR Guide: http://www.in.gov/dnr/fishwild/files...hing_guide.pdf
