Fertilizer and Lake O releases contribute to algae in the Caloosahatchee
Experts say that Lake Okeechobee releases are definitely a contributing factor to the algae in the Caloosahatchee River, but the chemicals from fertilizers are also adding to the gunky, green sight.
“It happens pretty much each year,” said Sweetwater Landing Marina owner Brandon Mayer. “It’s a normal occurrence.”
Mayer says he has gotten used to the slimy, green water surrounding the boats off State Road 31 and worrying his customers.
“A lot of customers just want to know if it’s anything that’s gonna be alarming health wise, or where they can’t get in the water,” Mayer said.
Experts say it is alarming and harmful to people and wildlife. One problem is the Lake Okeechobee releases that are sent down the Caloosahatchee, but another issue is something in people’s lawns and landscapes, fertilizers.
“Fertilizer is good as long as it’s just being applied during winter months, and being irrigated with standard irrigation,” said horticulturist at Seabreeze Landscapes Justen Dobbs.
Fertilizer’s needed to keep plants healthy, but not good during the summer months.
With the heavy rain during the summer, it causes fertilizers to run off into the water.
“We have a lot of rain run off that makes it’s way through everybody’s lawns, into the storm run off and, eventually, out into the gulf,” Dobbs said.
A Lee County ordinance doesn’t allow landscapers to use fertilizers with nitrogen or phosphorous during the months of summer to September. But, this ordinance doesn’t stop homeowners from using that kind of fertilizer on their lawns.
