Just go to the best looking flats with deeper water near by. Take plenty of 5" kalin grubs (white, chart, smoke) and use a 1/8 to 1/4 oz jig head with a large hook. Fan cast the flats and reel very slowly making sure you are keeping contact with the bottom or ticking the weeds. Try this at different locations on the flat especially where it drops into deeper water. I do this every April and it never fails to put alot of fish in the boat. The very best fishing of the day is usually from dawn till about 9 am especially if its sunny. If it is overcast they will stay shallower on the flats and are much easier to catch. Works on long sloping points as well. I wouldn't worry about the low water, they will still hit. Banks with clay always seem to be a plus. April is the best month of the year for numbers and this has worked for me.
