I've never fished the rock even once in my life. I've fished stocton and its gin clear most of the time. I've found that on Stocton the thermal kline in winter and in summer seems to be around 20 to 25ft or that deep on bottom of the water. You can fish fifty feet deep and go about 20ft down and catch fish if theres something holding them there. During the spring will be the easiest time to catch fish. Look for coves with brush on them or rocks that would hide a fish and throw there when the water turns about 58 to 65 degrees in temp from Late March thru April. They will be anywhere from 8 to 1ft deep. Hope this helps brother and welcome aboard.
