The Water Quality Committee and the Water Quality (WQ) Staff have been proactive in the planning and preparation of our waterways since our 2017 Harmful Algae Bloom (HAB). This season, water quality sampling and monitoring has been ongoing since April. Unfortunately, the TKPOA is at the infancy stages of experiencing another algae bloom for this season in the West Channel, East Channel and Lake Tallac.  


Our sampling results show that the bloom is a type of cyanobacteria that is primarily composed of Dolichospermum. This cyanobacteria is capable of producing toxins, but only low levels of Anotoxin-A have been detected. TKPOA has contacted the appropriate authorities, including Lahontan Regional Water Quality Control Board (LRWQCB).

The Water Quality Staff has placed caution signs (attached) at the Tahoe Keys entrances and around the waterways between Emerald Drive and Alpine Drive. This area (zone 16 on the harvesting map) is where the cyanobacteria has been detected. We will continue to conduct regular monitoring of the waterways.

Key precautions:

  • Avoid contact with algae or scum in the water
  • Keep children away from algae or scum
  • Fish caught in these waters should be cleaned with tap or bottled water.Guts should be thrown away
  • Do not let pets come into contact with algae / scum, drink the water or eat the scum on the shore
  • Do not drink lagoon water or use for cooking
  • Do not eat shellfish from the lagoons
