Reservoir Size:

Surface area is 46 acres; salt water recreational lake.

SolarBee Installation:

Date: January 2003:Installed two (2) SB10000s. A special coating was applied to address saltwater barnacle and mussel issues. Sacrificial anodes were installed to prevent corrosion. June 2005, original units replaced with the newer SB10000v12 model.

Project Objectives:

The initial objectives were to: 1) increase DO levels and prevent fish kills, 2) control nuisance algae blooms an associated unsightly mats and odors, 3) reduce fecal coliform counts by improved mixing and increasing water exposure to the sun’s UV light, and 4) reduce the need to pump high volumes of fresher water into the lake on a continual basis.

Project Results:

DO concentrations increased throughout the lake following the installation of the SolarBees. Owner reports fewer or no nuisance algal bloom events and associated floating algal scum, reduced need for pumping fresher water into the lake (thus saving energy), better fecal coliform counts, more stable pH values, lower chlorophyll a concentrations, and better water clarity.
