The TeamMeet the People Making Things Work

 

The Water Quality Department is responsible for harvesting and removing the weeds growing and accumulating in the Keys channels and waterways in the spring/summer months. The four employees responsible for the Water Department oversee this department as well, are responsible organizing, scheduling and administrating the additional 14 seasonal employees that operate the 4 weed harvester machines, 4 skimmer weed boats, trucks and 8 trailers; as well as maintaining equipment, servicing outboard motors and maintaining the trucks, trailers and boats. This office also addresses homeowner’s needs, requests and complaints. weed harvester

We have four weed-harvester machines that are deployed daily in our channels and dock areas harvesting and collecting the millfoil and other weed growth, and removing it from the water, helping to keep the channels clear. Notice that the harvesters only can get around dock where there is an 8 foot space between the docks, due to the paddle wheels on the side of the machine.

Weed Harvesting Schedule

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. [See schedule below] As of right now, weed pick up for those members that rake or pull weeds, this will be on call or will be picked up if identified by the TKPOA boat crews. To request a weed pickup from your dock please call the TKPOA Pavilion Office at 530-542-6444. This may change as the summer season goes on as we update our scheduling.

Currently our plan is to post the harvesting schedule every other Friday, for the following two weeks. We will post this schedule here on 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 7:30 AM to 4:00 PM. Our weed harvesting program for the Tahoe Keys is not an easy job, the Water Quality Department is dedicated to ensuring that all our waterways remain accessible and enjoyable for our homeowners and visitors.

For the curious, here is some data on the harvesters:

  • the 1983 6 foot harvester with a 5 foot cutting head holds 250 cu.ft or 9.3 yards of weeds per load
  • the 1991 8 foot harvester with an 8 foot cutting head holds 250 cu.ft. or 9.3 yards of weeds per load
  • the 2003 10 foot harvester with an 8 foot cutting head holds 1000 cu.ft or 37 yards of weeds per load
  • the 2005 8 foot harvester with an 8 foot cutting head holds 450 cu.ft or 17 yards of weeds per load

We average around 5,000 to 6,000 yards of weeds in the 5 month period of harvesting.

There are also crews in small boats, "skimmers", skimming the surface for the floating weeds, as well as collecting weeds that individual homeowners might have raked up by their docks.

Staff can be reached at (530)542-6451 and callers are requested to leave a message if staff is unavailable at the time. Messages can also be left with the front office staff at (530)542-6444, ext. 221.

Lagoon Water Quality

The Tahoe Keys lagoons are inter-connected to Lake Tahoe. Nutrients and fine sediments contained in the lagoon water can adversely impact the clarity of Lake Tahoe. In addition, the aquatic invasive species, aquatic weeds and non-native fish, can be spread to other parts of Lake Tahoe by boats and other human activity.

TKPOA is working with the Lahontan Regional Water Quality Control Board to develop ways to minimize the quantity of nutrients in the Tahoe Keys lagoon water. The primary method to reduce nutrients is to reduce the discharge of fertilizers that runoff into the lagoons during irrigation. TKPOA is educating its members and promotes the use of phosphorus-free fertilizers, it has also begun a process to notify its members who are observed to be over-irrigating their properties and creating runoff into the lagoons.

TKPOA is working to develop ways to minimize the quantity of fine sediments in the Tahoe Keys lagoon water. The primary method to reduce fine sediments is by increasing the number of properties that have Best Manage Practices (BMP) in place. To this end, all primary residence construction plans requiring City approval must be reviewed by ACC to ensure that BMPs are included where applicable.

TKPOA has cooperated with TRPA and TRCD in conducting scientific studies regarding ways to control the growth of aquatic weeds over the past three years. The results of those studies have shown that aquatic weeds can be controlled using harvesting (the current control method), bottom barriers, and aquatic herbicides. TKPOA is developing an integrated aquatic weed management plan (IMP) that will be based on the most cost-effective mix of the identified weed control methods. While harvesting and bottom barriers are currently allowed, the use of aquatic herbicides will require additional study and regulatory approval. To this end, TKPOA is just starting a program to comprehensively assess the impacts of aquatic herbicides to provide a scientific basis for regulatory consideration. This program is likely to take 3 years or more to complete.
