Again it has fallen a bit almost daily with the exceptions of a handful of days here and there. Whether through evaporation or drawdown it falls a little daily unless we are getting rain. That has been a constant. No refuting that. Some days more than others obviously in regards to falling. Been that way since early on into the drought. Its fluctuated by feet a few times this year as well.
Fish still bite and using the gates being open as a way to decide to fish or not might cost you a very good trip. I think the fish are less affected by it than if it had never had any fluctuations. I keep weekly records and have for the last 3-5 years as part of a weekly project I help with.
I don't need a bunch of tables and charts to tell me that in my own experience the bite is much less affected by it than some think. I am fortunate to spend a lot of days out there and have had some monster days even when gates are open. Just go fishing. You never know what might happen.
