Day Two Alum Treatment

Aquatechnex completed most of the main lake north of the Lighthouse yesterday.  Today we will be focusing on the area between the dam and the Light house as well as sending one boat through the causeway to focus on the western portion of the East Bay.

Tomorrow, the crew will relocate to the East Boat ramp to complete the East Bay zone.  The northern ski area will be treated on Thursday and then we will demobilize from the lake and see you in the fall.

Our team will be working from Holiday Harbor boat ramp today and tomorrow.  We will be starting treatments focusing on the north end of the main lake from the lighthouse to the causeway.  We will be treating the fingers off the northern portion of the main lake as well.
