I was on a local river in mid-Western Ontario a few nights ago and caught a dozen or so small rainbow that were rising to caddis flies. As I began to walk back to the car (at about 9:00 pm) a noticed a moderate hatch of mayflies (possibly brown drakes?). My questions are these:

1. Will the fish feed after dark on these mayfly duns?

2. Will there be a spinner fall worth fishing the next morning? (Please don't ask me to get up and go check - with a seven week old baby in the house, time on the river is pretty hard to come by!).

Thanks...
