A new area water park is already a hit less than a month after it opened. Surf Lagoon Water Park in Pooler officially opened May 23, and sales and marketing director Crystal Colson said that once school let out, the park started netting huge crowds. “We start to peak out around noon,” she said of the daily crowds, which often are lined up by 10:30 a.m.As soon as the gates opened on a recent day, the small trickle of 10-12 people started to grow.
