Not A Good Fish Day

Went to one of our local TWRA. Lake today outside temperature 60 degrees. Water very stained water temperature 61 degrees. We have fished this lake many times and thought we could find the bass. We ran the lake 5th hours and didn't find any large schools of bass.They seemed to disappear over the winter. We ran shallows and deep water, coves etc. .I don't know what we were doing wrong. I finally caught one bass off of point. We did see fish just not in great numbers. We saw pods of bait fish but only 2 or three bass around the pods. Any ideas.
