My hunch is that many of our reservoirs and lakes are icing out as I write this (e.g. Am. Falls) or will soon ice out in the next few weeks. I would like to know more about the timing of "turnover" in Idaho's reservoirs following ice out and how fishing is affected. The information on the internet says that fish basically quit biting for about 2 weeks following "turnover".
I am using the word "turnover" to describe the phenomenon in which the water temperature profile inverts from the winter stack-up to the summer stack-up. Apparently there is oxygen depleted water on the bottom of the reservoir during the winter and "turnover" mixes this water along with bottom scum thereby creating a temporary fish lockjaw.
Hopefully, we can create a database for when the best (and worst)fishing occurs with respect to ice-out for SE Idaho places like Am. Falls, Bear Lake, Pali
es, Chesterfield and wherever else folks are interested in. I don't know how long after ice-out that it takes for this "turnover" to happen nor whether the fish stop biting at all let alone how long they quit biting.
