Case Study for Customer Location CA93:
Reservoir or Lake Use:
This is a highly urbanized, fresh water lake utilized solely for
recreational purposes.
System Overview and Reservoir:
Lake # 2 is part of a 4-lake chain, totaling 68 acres. Lake #2
has a surface area of 4 acres; maximum depth is 12 ft, minimum
depth is 8 ft, average depth is 10 ft; volume is 41 acre-feet.
Apple Finger is 2.1 acres off of Lake #4 and Joe’s Finger is 1.3
acres off of Lake #1.
Reported Problem Before SolarBee Installation:
The primary objective is to provide control of blue-green algae
blooms, and associated odors and unsightly algal mats. Secondary
goal is to provide control of invasive aquatic weeds. This area
is a dead end cove with prevailing winds pushing water to the
dead end. Lake had experienced periodic fish kills due to low
DO.
SolarBee Installation:
Date: June 5, 2004. Installed one solar-powered SB10000V12. The
SolarBee was set in 10 ft of water with the intake tube set at 8
ft.
Results:
Following its installation, the SolarBee distributed DO
throughout the water column and likely prevented an otherwise
anticipated summer fish kill. Blue-greens blooms, surface scum,
and noxious odors were also controlled in Lake #4 throughout the
remainder of the year. During the winter, DOs generally remained
above 5 mg/L in the cove and throughout the water column. Water
quality continues to be good without blue-green blooms and
surface algal mats, and the owners are pleased with the
SolarBees’ performance. Since the original installation in Lake
# 2, additional SolarBees have been installed in Lake # 4 Apple
Finger (SB4000v12) and Lake #1’s Joe’s Finger (SB1250v12).
Results show effective blue-green bloom control, elimination of
surface scum and odors, and improved water clarity in these
additionally treated waters.
