I have followed them for 20+years on Cherokee and I have notes on the Stripers going back that far .I could almost tell you to the day where they would be.. The pattern is not the same this year or last ..Why?? Maybe the water has been to warm.But they do usually run up river to spawn and start back down the end of March or April .And by May or June they are at the dam. Heard this on the T.V. That the Salmon run in the west was running about a month late ?/Global Warming ?? Maybe that applies to to the Stripers .We had very little rain this year and the temperature has been real high.Maybe one of the TWRA Game Bio's.might know more about this.. YANK
