I found one of the boat ramps off of 74. Going west on 74 about 40 miles from Wilmington just take a left off of 74, and follow the signs to the Lake Waccamaw state park. You will see a public access boat ramp on the right hand side around 3 or 4 miles off of 74. Can someone post where the second boat ramp is? I read in this link that there is a second public boat ramp at Lake Waccamaw. The boat ramp was too crowded when I went. On a side note, can someone tell me how the fishing is here i.e. bass, crappie, etc?
