Harvesting is the primary control method available to the Tahoe Keys today. In 1984, roughly100 cubic yardswere removed from the lagoons and nearly10,000 cubic yards were removed in 2020. Water Quality operations cost around $600,000 a year but the TKPOA is clearly losing ground with these mechanical harvesting methods alone.
Throughout the summer months the TKPOA operates harvesters that remove vegetation from designated sections
July-August harvesters focus on navigation lanes so boaters can travel through the lagoons
During the last few weeks of the harvesting season harvesters focus on removing as much vegetation as possible by harvesting the entire section between homeowner docks. This helps to reduce available nutrients and may possibly help reduce vegetation growth the following season.
Homeowners can help assist in fragment control by skimming around their docks and stacking the weeds on the end of their docks.
Skimmer crews will come by and pick up the piles from your docks twice a week so they can be disposed of properly.

TKPOA Harvesting Equipment
The TKPOA Operates 3 Harvesters throughout the summer. Two harvesters continuously operate in the West Lagoon and one moves from Lake Tallac to the East Lagoon. The TKPOA also operates skimming equipment such as the Weedoo Tiger Cat and Aqua Harvester along with skimmer boats to collect weed fragment throughout the Lagoons.
Check out our current fleet of harvesting and fragment control equipment!
This harvester can collect 16 cubic yards of biomass for each load. It is small enough to go in between docks and large enough to effectively clear navigation lanes.
Harvester 4 is our largest harvester and can hold up to 37 cubic yards of weeds. Due to the size of this harvester it is difficult to go in between docks
Harvester 5 is our smallest harvester and can collect around 4 cubic yards of vegetation. This harvester maintains Lake Tallac and the East Lagoon. At the end of the season harvester 5 focuses on harvesting between docks.
The Omnicat is a passive skimming pontoon with a collection device between the pontoons. This vessel was designed to skim navigation lanes to collect aquatic weed fragments. It is not able to collect fragments between individual docks due to its size.
The Tiger Cat was purchased in 2020 using funds from the 2020 special assessment. This piece of equipment can effectively collect weed fragment and cut close to docks with its cutting bar.
The Aqua Harvester was purchased in 2020 using funds from the 2020 special assessment. This piece of equipment can effectively collect weed fragments in-between docks and in navigation lanes with minimal manual labor.
The TKPOA has five vessels used by the skimming crews. These are used for pile pick-ups and fragment collection.
