Lotus Lake Coverage Map

Lotus Lake application coverage map dual zone

HAB has downloaded and processed the alum application data from the barge’s guidance and dose control computer system.  The dual dose rate coverage map shows each individual application path and the associated dose rates that were recorded over the course of the Lotus Lake application.  We are extremely pleased with the precise application and uniform coverage of the two planned application zones.  There are no gaps in coverage, which is important to ensure that the sediments received the appropriate alum dose.  Gaps in coverage can allow pockets of internal phosphorus loading to the water column and subsequent use by the algae for growth.  The comprehensive and complete coverage, at the two prescribed doses, optimizes the longevity and effectiveness of the lake restoration project.
