Our monitoring program aims to ensure that new infestations are reported, confirmed, and responded to as soon
as possible to minimize environmental and economic impacts resulting from an infestation.
September, 2012, the Whatcom County Noxious Weed Board, with assistance from
the Washington State Department of Ecology and the City of Bellingham,
completed an aquatic invasive species inventory of the littoral zone of Lake
Whatcom. The goals of the inventory were
to establish a baseline of aquatic invasive species present in the lake and their
distributions to assist in the development of aquatic invasive species response
strategies. The survey was conducted by
boat over four days in August and September.
Submersed species were collected using a grab sampling method that
involved throwing a weighted rake attached to a rope down to depths of 30
feet. Emergent shoreline species were
recorded based on visual observations of the shoreline. No new aquatic invasive species or new Asian clam infestations were
discovered as a result of this inventory.
Out of the 38 plant species that were found, 24 were native and 14 were
introduced. Out of the 14 introduced
species found, 11 are shoreline or nearshore plants while the other three are
submersed invasive species and include: fragrant water lily, Eurasian
watermilfoil, and curly-leaf pondweed (2012 Lake Whatcom Inventory Report).
Lake Whatcom Management Program staff also continued to conduct shoreline surveys for Asian clams and to monitor existing infestations. Also, in 2012, the Washington Department of Fish and Wildlife and the Whatcom County Noxious Weed Board engaged in monitoring efforts for zebra/quagga mussels in Lake Whatcom. No zebra/quagga mussels were detected through these activities in 2012.
In 2013, the Aquatic Invasive Species Program plans to develop its capability to conduct more frequent lake monitoring events for zebra/quagga mussels and other aquatic invasive species in the lake.
The map below was created using information collected during the aquatic invasive species inventory conducted in 2012. Several species of shoreline and submersed invasive plants that are found in Lake Whatcom are highlighted using various colors (click to enlarge).
