I am trying to learn everything I can about western WA stillwater aquatic food chain plus when the bugs in the food change hatch. Are there any hatch charts and/or books; videos specificly for western WA?
I am not aware of any hatch charts and/or books; videos specifically for western WA. However, all you need do is to access the generalized emergence chart for WA on my website, and look in the Water (Still) as opposed to Water (Move) column.
Thanks for the complement. Yes, the elevation of a lake would be expected to have some impact on the timing of hatches from that lake. For example, the Chopaka Callibaetis mayfly hatches could be expected to occur perhaps a week or two later than those of a Western Washington lowland lake like Rattlesnake. A given species of insect will emerge after having absorbed the number of thermal units required for that species to develop to maturity, and the higher the elevation of the lake is, the fewer thermal units are likely to be absorbed by a given date. However, my hatch chart does attempt to take this variation into effect.
