Location with Black crappie

My brother came up from Massachusetts for some spring time Crappie action and it was hot and heavy the first day (Saturday) but Sunday was a bit tougher. We had overcast skys on Saturday with a slight breeze so they (the weather man) say turned out to be 15mph + but the fish were very active. Water temp between 49-51 the big slabs have moved in to do their business. We found these crappie in 4-6 feet of water using a 1/16 oz chartreuse jig head with a small 1 minnow profile bait and various color tube jigs.
