Good day. The harvesting season is right around the corner and I wanted to give everyone a brief overview of how harvesting operations will be conducted and what the upcoming projects will be occurring throughout the season.

Just a reminder, my name is Greg Hoover and I am the Water Quality Manager and Aquatic Invasive Species (AIS) Management Coordinator for the TKPOA. I will be overseeing all of the harvesting and fragment control operations, spill response; also the AIS Program based the direction from the TKPOA Board of Directors and Water Quality Committee.

Our harvesting schedule will be similar to last year. The West Channel will be harvested on a 20 day (19 harvesting days and one maintenance day) rotation and the East Channel / Lake Tallac Lagoon will be harvested on a 25 day (13 days East Channel / 11 days in Lake Tallac Lagoon followed by a maintenance day in between) rotation.

Going into the 2018 harvesting season, the Board of Directors and the Water Quality Committee’s intent was to reduce the amount of weed fragments within our lagoons and waterways. The TKPOA has purchased and installed a Bubble Curtain in the West Channel between the Tahoe Keys lagoons and Lake Tahoe. The Bubble Curtain consists of multiple hoses that are submerged at the bottom of the waterway fed by an air compressor on the shore to push bubbles in a sheet, throughout the water column, to the surface. It was installed in a “V” formation to drive submerged plant fragments to the water’s surface, and then to the edges of the channel to ease collection and removal. An additional benefit of the bubble curtain is that it will trap the stray fragments without impeding boating activity. This technology is being used in other locations around the world (including places with currents, tides and swells) to prevent debris from moving through an area—this is the first time this technology has been used to prevent the spread of aquatic invasive plants. The Association has also purchased two Sea Bins that will be placed on either end of the bubble curtain to capture and remove fragments as they are corralled. These Sea Bins will be placed in the West Channel later in the season.

We will also have many different projects this year that will support our overall AIS Integrated Management Plan. These projects will include: conducting Hydro-acoustic mapping of our lagoons on a two week basis, monthly water data collection, algae monitoring, annual plant survey at the end of June, and weekly monitoring of the boat backup station. All of our past, current and future project information along with our latest updates can be found at I will update that members as the season goes on or if there are any changes to our AIS Program.

Our plan is to post the harvesting schedule every other Friday, for the following two weeks. We will post this schedule via the TKPOA website and TKPOA Staff will also send out an email blast that includes those TKPOA members that have submitted valid email addresses.

All of the harvesting and maintenance tasks will take place during our summer season (June – October), Monday through Friday from approximately 7:30AM to 4:30 PM.

I look forward to the challenge this summer and getting out on the Tahoe Keys waterways and seeing our TKPOA Water Quality Crew at work as well as seeing the TKPOA Members enjoy their time on the water. If you have any questions about the harvesting schedule or our AIS Program, contact the main office for information at (530) 542-6444. If they cannot answer your questions you will be referred to me – Greg Hoover, Water Quality Manager / (AIS) Management Coordinator.
