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?

Hi Old trout-

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.

I just discovered your chart tonight, and it as others have said, is INCREDIBLE. I am currently reading Bug Water by Arlen Thomason and it is certainly helpful to have such a resource in hand when reading this book. Thank you so much for creating this chart and I will certainly relish this for the indefinite future. Its incredible and you are such a modest guy. Thank you again, but I am not sure that really does justice for such an amazing resource.
