Approval has just been granted for the the mechanical harvester to be operated from June to September this year and required for the next five years as well.

The Friends of Georgica Pond Foundation, a group of pondfront property owners, know that removing the plant material is particularly helpful in lowering phosphorous levels in the pond. By doing so, “harmful algal blooms and ecological crisis” can be prevented. There is a definite correlation between operation of the weed harvester and improved water quality.

]]> Aquatic Weed Harvesting Helps Reduce Toxic Algae in Georgica Pond https://aquarius-systems.com/aquatic-weed-harvester-helps-to-restore-pond/ Sat, 02 Dec 2017 21:12:36 +0000 https://aquariussystems.wordpress.com/?p=720 Efforts to restore Georgica Pond are proving to be successful thanks in part to the help of an aquatic weed harvester.

Georgica Pond has been invaded by toxic cyanobacteria, or blue-green algae, in recent years, which can cause serious health problems.  For the second consecutive year, the foundation has leased an aquatic weed harvester to remove plant material, or macroalgae, from the pond, which releases nitrogen and phosphorous as it decays and is believed to promote cyanobacteria.

The mechanical harvester 32,700 pounds of this material represent 6% of the pond’s nitrogen load and 12% of its phosphorous load; down from 2016 when 55,740 pounds, representing 13% of the nitrogen load and 23% of the phosphorous load, were harvested.  Officials say part of the reason for the decrease in 2017 was due to the large quantity of macroalgae harvester the previous year.
