The West winds last night blew in warmer water this morning. Our intake temp on the bottom in 50' Just West of the pier went from 53* yesterday all do to 74 degrees at this moment. You more than likely had colder water yesterday and warmer water today. When the lake upwells and colder water comes in, the perch usually come into shallower water. When warm water comes in, they move back out deeper for the most part. Until we get another East or NE blow, we will be stuck with warm water.
