Johnny Franks wiped his brow and hopped into his johnboat on another blazingly hot summer afternoon in Southeastern North Carolina.
When asked why he had come to Sutton Lake when the temperature, counting the humidity, was in the triple digits, he didn't pause.
"The fish," Franks said with a smile as he prepared to push off from the N.C. Wildlife Resources Commission boat launch at the lake. "This is some of the best fishing in the area, and they don't mind the heat."
For a lake created to cool a power plant that doesn't exist anymore, Sutton Lake is certainly popular.
On a typical day, if it's not too windy, you're likely to find fishermen trying their luck in one of North Carolina's hottest bass fisheries and possibly even a few kayakers enjoying the waters of one of the region's largest manmade lakes that happens to be within a short hop of downtown Wilmington − although it's a bit off the beaten path.
Blessed with warm and super-clear water, Sutton Lake is an angler's freshwater dream. But the lake's original purpose and proximity to the old Carolina Power & Light, and then Duke Energy, coal-fired power plant − since replaced by a natural gas plant − and former ash ponds means the waterway hasn't always been as pristine as it looks on the surface.
And 2018's Hurricane Florence, which collapsed the nearly 1,100-acre lake's dam after swamping the region with nearly 2 feet of rain, washing away a chunk of nearby U.S. 421, reinforced the power of Mother Nature and Sutton's fragility.
Let's take a look at the history and secrets of the lake that remains a scenic and often overlooked environmental gem for local anglers and boaters.
From fishing to boating, here are 8 things to know about Sutton Lake in Wilmington
Want a lake? Allow fishing
Built in the early 1970s to cool the nearby coal-powered power plant, the lake immediately became a popular fishing hole.
That was by design.
"One stipulation from the state for construction of the lake was that it had to be open to the public for fishing, and it's now one of the best destinations in Eastern North Carolina for large-mouth bass and other freshwater fish," said Kyle Rachels, a biologist with the N.C. Wildlife Resources Commission.
There are several factors that contribute to Sutton Lake being such a good habitat for fish.
First, the lake is littered with submerged tree stumps and other woody debris that make it a safe haven for fish. The state also periodically sinks more habitat, some natural and some artificial, into the lake to enhance the marine environment.
"That really provides cover for the juvenile fish to escape predation, and that in turn allows them to grow up and contribute to the lake's fish population," Rachels said.
Thanks to the nearby power plant, which still draws and releases water from the lake for cooling purposes, Sutton's waters are warmer than the adjacent Cape Fear River.
"That means the fish can grow faster and larger," Rachels said, referring to the heat-charged water that the Duke plant releases. "It's more like Florida or Puerto Rico than North Carolina."
That most fishermen who frequent the lake also practice catch-and-release, especially when it comes to Sutton's signature largemouth bass, means the fish live a good and old life.
Freshwater fish aren't the only animals that enjoy Sutton, which is surrounded by sandy pine savannahs, some of which are state game lands.
Because water is sometimes drawn into the lake from the nearby Cape Fear, which is brackish, to maintain the water level, saltwater critters sometimes sneak into Sutton.
"We've seen flounder, Atlantic needlefish and even blue crabs in there," Rachels said, noting that the salinity levels in Sutton aren't high enough to adversely impact freshwater fish species.
Bigger critters, including cormorants, herons and alligators, also are drawn to the lake.
"And some of them are of a pretty significant size," Rachels said with a laugh, referring to the toothy reptiles.
The lake remains 'safe'
Duke Energy, the successor to Carolina Power & Light, still manages Sutton Lake and the adjoining shoreline.
"In 2016, Sutton Lake was reclassified as Waters of the U.S. (WOTUS), but Duke Energy still owns all the property surrounding the lake, including the lake intake structure, emergency spillway and the dam separating the lake from the Cape Fear River," said Duke spokesperson Ben Williamson in a statement. "There are ongoing maintenance activities that we still perform on the lake to ensure that reliable operations can be maintained and within specific permit requirements."
The utility company also continues to test the lake for contaminants, a lingering concern since coal ash that used to be stored on the Sutton power plant property in open pits − now a covered and sealed landfill − is known to have leached into nearby groundwater.
"Duke Energy still uses Sutton Lake as a cooling pond for ongoing power plant operations and we maintain environmental permits, perform routine sampling and other necessary activities required to use the lake for cooling on an ongoing basis," Williamson said. "Extensive scientific monitoring of the lake has been underway for decades and confirm the fish are thriving and the lake remains safe to use for recreational purposes like fishing."
Rachels said testing by the state also has shown the lake's fish to be safe, and there are no Sutton-specific rules and regulations regarding consumption beyond the general statewide advisory for pregnant women and children to limit eating fish known to be high in mercury.
Florence and flooding
Largely out of sight and requiring a trek on dusty dirt roads to get there, most Wilmington residents probably never gave Sutton Lake much thought.
Then Hurricane Florence hit.
The 2018 storm dumped nearly 2 feet of rain on the Port City, and even more inland. And when all that rain started flowing down the Cape Fear River toward the Atlantic, it crested over the dike separating Sutton from the river.
The increased water levels in the lake then collapsed Sutton's eastern berm, sending floodwater cascading toward U.S. 421. eventually washing away a nearly 500-foot-long chunk of the roadway near the New Hanover-Pender County line and adding to Wilmington's isolation post-Florence.
Rachels said while the Cape Fear and Northeast Cape Fear rivers suffered substantial fish kills post-Florence due to low oxygen levels, Sutton proved to be a bit of a reprieve for fish and didn't suffer the same low dissolved-oxygen levels.
"And that meant the fish populations rebounded really quickly," Rachels said of the lake post-repairs. "A year later you couldn't tell anything bad had really happened, unlike the situation in the rivers that took several years for fish stocks to recover."
'Love this place'
While Sutton might be a fisherman's paradise, it still is subject to the whims of Mother Nature.
Storms can blow in quickly, turning the lake's water rough in moments.
"As soon as you get a little bit of wind, you can go from flat water to white caps real fast, so you have to make sure to have your life jacket,“ Rachels said.
As he prepared to launch from the wildlife boat ramp, Mike Sanders fiddled with his life jacket's straps and checked his fishing rod was securely fastened to his kayak.
"Love this place. It's just so quiet and peaceful," said the Columbus County resident. "But you also have to respect it."
And the fish?
"You have to respect them, too," Sanders said with a laugh.
What to know before you go
Sutton Lake is located roughly 7 miles north of downtown Wilmington off U.S. 421.
Access to the manmade reservoir, which is actually a series of lakes, is via Sutton Lake Road off U.S. 421 and then some curvy driving on dirt roads that wind around the Duke coal ash landfill. There is a sign on U.S. 421 for the public boat ramp.
Boating and kayaking access to the lake is via the wildlife resources public boat ramp, 301 Sutton Lake Road, which offers free parking and trailer parking and also a small pier for landlubbers who want to try their fishing luck from shore.
Boaters and fishermen are advised that the ramp area doesn't include any services or concessions, so please pack accordingly.
