The East Bay of Canyon Lake was treated by Aquatechnex Biologists yesterday and the team will be rapping up this round of work treating the north Ski Area today.  We will then be demobilizing from the lake.  The plan generally is to return in the late summer to perform the second dose.

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.

Rapping Up First 2017 Alum Treatment Today

Aquatechnex will be demobilizing from the lake this afternoon after completing the first Alum treatment of 2017.  The silt load from the recent rains generally carries a considerable phosphorus load.  The objective of early treatment was to get in the water prior to spring Algae Bloom that has been a treatment issue in the past.  Water transparency started the week about 2 inches and was measured at 3 feet today using a Secchi disk.

At this point the second treatment is scheduled for September of this year.  We will be using this page to communicate again as that work gets closer.
