Complete 3-D lake mapping
HAB Aquatic Solutions offers comprehensive bathymetric mapping services. An accurate and precise lake map is one of the required tools for determining the proper treatment dose and designing an appropriate application plan. These maps will also be very popular with the anglers and boaters at your lake!
Precise dose calculation
The proper dose is a critical component in effective, long-lasting lake treatments. No two lakes are the same and each lake will require a specific treatment dose. HAB Aquatic Solutions Treatment has years of experience in determining dose rates across a wide range of lake types and will tailor the treatment dose specifically to your lake.
Pinpoint, GPS guided application
Exact placement of the alum formulation is another critical component of a successful and effective lake treatment. HAB's application barges are equipped with state-of-the-art GPS guidance systems to ensure an accurate treatment.
The pumping systems are automatically controlled by computerized GPS systems that vary the pumping rate with boat speed and bathymetric measurements to ensure an effective dose of chemicals throughout the lake.
In-Lake Treatment System
HAB's In-Lake Treatment System is used to control internal phosphorus loading, resulting in less algae and better water quality. This approach is not toxic to the algae, but rather reduces the amount of phosphorus available for algal growth by retarding phosphorus inputs from the sediment for years!
During HAB's In-Lake Treatment, the alum formulation is added to the lake water from a barge where it forms a fluffy, cotton ball-like substance known as a colloidal aluminum hydroxide floc which binds to phosphorus. The floc settles out of the lake and forms a chemical barrier between the bottom sediments and the water. The floc actively binds and retains phosphorus that would otherwise escape to the overlying water, thus reducing the amount of lake algae.
On-Shore Treatment System
HAB's On-Shore Treatment System is used to control external sources of phosphorus (for example, stormwater entering a lake from a ditch or culvert). With this approach, the chemical formulation is injected into the external water source and binds the phosphorus to the floc before it enters the lake, thus rendering the phosphorus unavailable for algal growth.
Sediment Core Collection and Analysis
Sources of phosphorus that come from within the lake (internal loading) have often been underestimated or overlooked in lake management. HAB utilizes specialized lakebed coring equipment to collect intact and undisturbed sediment cores from the bottom of lakes. We then carefully section the cores to gather discrete samples of sediments from different depths. The samples are analyzed for different fractions of phosphorus that give us critical information about the importance of internal loading in your lake and the amount of alum that would be needed if an alum application was performed.
