Bob D,

I don't understand yer reply. Is that two hours before/after high tide? Or low tide?

I know that the few rivers where I've noticed a relation to tide it seemed like the fish came in on the incoming tide, with the bulk of em coming in at low slack to a couple of hours after. Not a hard and fast rule but a strong trend.

Anyone else have any knowledge of this?

I seem to remember an article in STS that said that fish (Salmon? can't remember) travel an average of four miles an hour and that if you can calculate how many river miles from the mouth you can pretty ell figure when the fish will get there.

Would appreciate hearing other peoples experience/theories.

Sincerely,
Roger
