Greenfield Lake is a former millpond built in the 1730s by Dr. Samuel Green for rice production, now encompassing approximately 150 acres of water in New Hanover County, North Carolina. This shallow lake averages 4-5 feet in depth with the deepest areas near the dam reaching 7-8 feet. Located within a 250-acre park in downtown Wilmington, the lake features a shoreline covered with cypress, oak, and pine trees surrounded by dense flowering shrubs including azaleas. The lake serves as both a popular urban fishing destination and year-round birding oasis, offering anglers a protected environment where they can escape wind conditions that might affect larger bodies of water.
