Canyon Lake Day Two

Aquatechnex biologists will be treating Canyon Lake again today with Aluminum Sulfate to remove and sequester Phosphorus.  This work will be performed from the Holiday Harbor ramp and applications will be primarily in that area and north.  Tomorrow we will be focused on the north end of the main lake and Thursday the east arm.

We had a few questions about swimming near the applications yesterday.  Aluminum Sulfate forms a precipitate with the phosphorus and settles rapidly.  This products is used extensively in drinking water treatment plants that deliver potable water to your homes and is fully certified to be used in potable water systems without any restrictions on water use.

There are some pictures on our twitter and facebook pages that can be viewed from the links on the right.

Treatment Rap Up Friday May 20th

The 2016 spring Alum treatment for Canyon Lake to sequester phosphorus will be rapping up this morning about 10 am.

Yesterday’s treatments addressed the East Arm of the lake.  About 1 pm we noted some light floc floating near Indian Beach and halted the application while we broke that up with boat wave action.  We moved to complete the first ever treatment of the North Ski Area in the afternoon.

Today the teams are completing application on the East Arm from the East Ramp area.  We plan to demobilize from the lake late morning.

The next treatment of the lake under this contract is expected to occur in September after the Labor Day Weekend.

Transparency Readings in the Main lake are well above 13 feet and things look good.

Our plan at this point is to treat the main lake on Tuesday and Wednesday, move to the East Arm mid to late Wednesday, finish the East Arm on Thursday or Friday morning and this year the treatment will also target the North of the Causeway Waterski area north of the main lake, that work is planned for Friday.

Interested parties can check back here for daily updates during application, we will also be using our twitter feed that you can access @aquatechnex or from this page for more constant information.
