Lotus Lake Coverage Map

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…

Project Complete!

Today the Lotus Lake alum application project was completed on schedule! As planned, the exact dose of over 108,000 gallons of alum was applied in a precise, uniform, and most importantly, safe manner. There is no greater measure of success than safety and Lotus Lake marks HAB’s 75th project without a safety incident. A special…

Bald Eagle Lake, MN

The Lotus Lake alum application was suspended today for high winds which can create unsafe working conditions and can cause the floc to drift before it reaches the lakebed.  The forecast calls for lower wind speeds tomorrow and HAB plans to resume the application in the morning. In addition to the updates on progress at…

Precise Alum Application

HAB powered through a chilly, steady rain today to apply 22,000 gallons of alum and complete over 75% of the total dose for the Lotus Lake project!  An important feature of a successful alum application is the formation of the floc and the precise placement of the floc on the lakebed. The floc is formed…

Demonstration Day!

Today marked the second full day of application and the lake was busy with visitors and observers.  Nearly 27,000 gallons of alum was applied to Lotus Lake and the project continues to proceed smoothly.  A group of people took advantage of an afternoon break in the rain and gathered to participate in the Lotus Lake…

Environmental Testing

HAB had a full and productive day of application at Lotus Lake today and applied over 26,000 gallons of alum to a 57 acre zone.  We also spent time conducting our daily environmental testing of the lake water.  Alum is widely used in lakes and the drinking/wastewater treatment industry due to it’s known safety.  In…

The Project Begins!

HAB spent the first day of the Lotus Lake project preparing equipment for the application.  This included assembly of the barge’s application boom, programming the barge’s computerized dosing system, launching the barge into the lake, setting up on-shore storage tanks and confirming the delivery plan for the alum.  A small restricted work area was established…

How Does an Alum Application Affect Fish and Plants?

Aluminum is considered a non-essential metal because fish and other aquatic life do not need it to function. There is a large body of scientific literature documenting the safe use of alum in lake environment conditions, which has allowed the North American
Lake Management Society to fully endorse its use (NALMS, 2017).

Is Alum Safe?

Alum has been repeatedly shown to be safe for humans. Alum is a common
food additive and has also been used for decades to clean our drinking
water before consumption. HAB uses the exact same drinking water certified
alum when preforming a lake improvement application.
