This marked my 30th fly rod species in Missouri since moving last mid-July. 9 months. Not bad, especially considering this period included the Winter months!
In ~15 years of flyfishing in Iowa, to the best of my recollection, I managed 38 species in-state.
Without going Micro, my list of possibilities is growing shorter. Fish still on the "would love to catch on a fly here" list include:
Longnose Gar
Rock Bass
Blue Catfish
Hybrid Striped Bass
Bowfin
Warmouth
Redspotted Sunfish
Chain Pickerel
Flier
Brown Trout
I'm sure there are others I could go after as well...various suckers, bigmouth buffalo, smallmouth buffalo, black crappie, flathead catfish, muskie...
I haven't set any deadlines, so I'm in no hurry.
Rock Bass is probably the easiest on the list, you suppose? Or at least requires the least travel?
