Why is lake lanier green

Heavy rains from remnants of Hurricane Delta, combined with storm-water runoff and excess debris in Lake Lanier have caused algae blooms in multiple locations.

The Lake Lanier Association was notified and initiated testing of the green patch along the shoreline in Flat Creek. Certain types of algae in Lanier fluctuate with conditions. Algae is part of a healthy aquatic food chain, and many types are harmless. However, some types can produce dangerous toxins. Until now there have been no documented instances of this type of algae blooms in the lake.

The association issued a warning for people and their pets. By way of exercising caution, if any of these conditions are present, do not go into the water.

After getting gas and skipping out on paying for it, they skidded off a bridge while crossing the lake and disappeared.

The following year, a fisherman came across a decomposed, unidentifiable body floating near one of the bridges. Which meant that the body found way back in must have belonged to her friend, Parker Young. They had seen Parker Young themselves, wearing the blue dress she had borrowed that night from Roberts, wandering near the bridge.

With her handless arms, so the story goes, she snatches unsuspecting lake-goers and drags them to the bottom. I had no idea Lake Lanier was lethal the first few years I lived in Georgia.

I was simply taken in by its beauty. Thickets of lush green groves, mainly oaks and hickories, encircle sparkling blue water. It is a vibrant and diverse ecosystem, especially on the southern end. Latinx, Asian, and Black visitors fill the surrounding parks. Every summer, our family joins them.

We toss towels and flotation devices into the car, and head to the crescent beach of Buford Dam Park. The crisp savory scent of barbecue wafts through the air. Frisbees and picnic baskets blanket the grassy knolls. Geese and ducks waddle among them in search of leftovers. The swimming hole, far from any boating area, is calm, the sand underfoot soft. My three daughters have spent hours splashing in the clear shallow water and trying to catch fish that encircle their feet.

After this horrific incident, I began taking a hard look into the other deaths—the dozens of collisions, the drownings of swimmers who disappeared after jumping in, and the drivers who rode their vehicles into the lake.

Our family does not boat, jet ski, or tube at Lake Lanier. Our radius extends only to designated swimming areas or trails. Still, when I learned how many people had died, it was difficult for me to reconcile what seemed like such a serene place with so much tragedy. Forsyth County, which sits on the western side, was once part of the Cherokee Nation. In the s, the U. A second expulsion occurred eighty years later, this time involving a different community.

Up until , some 1, Black people owned land and operated businesses in Forsyth County. That fall, on September 9, an eighteen-year-old white woman named Mae Crow was raped and murdered close to Browns Bridge on the banks of the Chattahoochee River, in a village called Oscarville.

The crimes were pinned on four young Black people who happened to live nearby. He was shot, dragged through the streets, and hanged from a telephone pole just outside the courthouse in Cumming, the county seat. White mobs known as night riders went door to door with torches and guns, burning down Black churches and businesses, and demanding that all Black residents of Forsyth County vacate immediately. The residents quickly abandoned their land, their crops, their homes, and most of their belongings, and the whites picked over and pillaged what remained.

Five thousand people gathered to watch the two teenage boys be hanged. It is widely believed that Edwards, Knox, and Daniel were innocent of the crime. When Lake Lanier was formed in the s, it washed over Oscarville and turned it into an underwater ghost town.

And, incredibly, Forsyth County remained an all-white county for a few more decades. He was met with white counter-protestors and violence. It was the largest civil rights demonstration since Dr. Therefore, oxygen production in the thermocline begins to decline after the lake stratifies.

By summer's end, the lake is strongly stratified. The epilimnion is warm; it receives sunlight and has plenty of oxygen. Water temperature and oxygen concentrations within the thermocline are both lower, but still often provide acceptable habitat for cool water fish species like stripers and walleye.

In the hypolimnion deeper than 60 feet , the water is stagnant, cold, and low in oxygen less than 3 parts per million or ppm. Fish cannot survive in this deepest layer when dissolved oxygen drops much below 3 ppm.

As the oxygen concentrations get low, some metals and sulfides in the lake sediments become soluble. These dissolve in the water and are passed downstream as water leaves Lake Lanier and enters the river. This is first noticeable in late September or early October, when these metals and sulfides give the river water its distinctive fall colors and a rotten egg smell. Although these are stressors for the river fish, low oxygen concentrations and high metal and sulfide concentrations are very rarely associated with fish mortality in the river.

The river water becomes re-aerated quickly as it flows downstream, and fish in the river avoid water with low dissolved oxygen by finding seeps, springs or feeder streams that have higher dissolved oxygen and lower metal and sulfide concentrations. However, trout fishing in the river near the dam suffers in the fall, because of these water quality conditions.

Prior to the s, oxygen concentrations greater than 5 ppm and temperatures in the thermocline of Lake Lanier, a young reservoir at that time, were adequate to allow trout to survive.

Since then, organic matter entering the lake has increased, and the oxygen needs of trout can no longer be met. There just isn't enough oxygen to keep trout alive through this critical summer period. Today striped bass still find enough oxygen and adequate cool water habitat in the lake's thermocline to survive the summer; however, they can be stressed by low oxygen conditions 2—4 ppm.

In the fall, as air temperatures drop, the lake begins to lose heat, and the process of de-stratification begins. The warm water of the epilimnion cools and becomes deeper and denser. It still has lots of oxygen.

As the epilimnions density approaches the density of the hypolimnion, mixing of the layers can take place. When this happens the stratification is broken and the bottom water mixes with the surface water, and the lake is no longer stratified.

This event is called "Lake Turnover, and generally occurs around Christmas each year. After the mixing there are no layers, and the entire lake will have high oxygen concentrations. Within a few days after lake turnover, the dissolved metals become insoluble and settle to the bottom.

This leaves the lake water clear from the top to bottom, and the river water clears as well.
