Just got done fishing the French and Waterloo creek along with ensign hollow for 3 days. Very nice creeks and both the french had large fish just very hard to not spook and catch. Saw lots of wild parsnip and stayed clear thanks for the tip.
Camp was nice for 2 nights at french creek and was going to camp at ensign hollow but rain was on its way and I was only 60miles from waterloo. On another trip 2 weeks ago I fished spring branch lots of big fish and hard to catch.
Thanks to all the good info everyone gave me. Will plan on fishing Iowa when I visit my son.
