Encouraging news about Indiana smallmouth streams: Some of the great spawns of 2004, 2005, 2007 etc are starting to reach catchable size (8-10"). I don't try to catch these fish, but they are so aggressive. Minnow populations appear to be recovering as well. Water conditions also seem like a major improvement over last year's algae events. All hope is not lost for some of our streams that have been producing mediocre fishing for a year, year and a half.
I've mostly stepped away to try new creeks and rivers in 2010 and have found some new favorites. Numbers of fish caught per hour are way up. May, June, and July averaged 4.19 Smallmouth per hour (4.58 overall). Certain this is my best three month average. Not many 18-20"ers in there. Probably a factor of stream size, and large smallie populations somewhat slowing growth...
For now, I love the action and it seems the bigger flows aren't in terrible shape either!
Get out and fish!
