You can't catch 'em if there not there.And as i've maintained before in the last 4 or 5 yrs they simply haven't been there like before from the upper stretch of the Main Branch all the way to Channahon which with the exception of the short stretch from Channahon is virtually the entire river.Last year just about the only good action came in that short stretch which is best floated due to deeper water & private property.Until a few yrs ago the river produced good #s of 16-19+ smallies thruout its length and was the best big smallie river in Ill.But every year the algae growth and the intense weed growth became worse.Silt also got much worse in the slower near shore water where spawning would take place. Like the song says "...more people more scars upon the land". For most of the year the streambed couldn't even be seen covered as it was by algae,weed or silt. I believe these factors combined with excessive rainfall every year during spawning time resulted in multi year poor spawns.When those big old bass died off they left little behind.That's the long & short of it as far as I can see.For the better part of 10 yrs I had pretty consistent good fishing in the Dupe.These days after early spring I don't much bother with it anymore.
