Aquatechnex has expanded operations into the State of Montana starting May 1, 2021. Montana water ways have been plagued by invasive aquatic weeds such as Eurasian Milfoil and are starting to see episodes of Harmful Algae Blooms (HAB). Aquatechnex biologists are expert in developing and implementing management programs to restore lakes and river systems impacted […]

American Lake is a 1,200 acre waterbody in Pierce County, WA. The lake was heavily impacted by the invasive aquatic weed Eurasian Milfoil. The lake residents and the City of Lakewood formed a Lake Management District to combat this growth and received grant funding from the Washington Department of Ecology. In 2019 our team designed […]
Vancouver Lake in Clark County, WA is a 2,700 acre waterbody that is heavily used for sailing and rowing competitions. The lake is relatively shallow and the invasive aquatic weed Eurasian Milfoil was discovered in the lake about three years ago. In partnership with the Friends of Vancouver Lake, our team developed and implemented a […]
Kitsap Lake is a 256 acre waterbody in the Puget Sound Region and for the past number of years has been plagued with Harmful Algae Blooms (HAB). HAB presence in a lake can be a threat to wildlife, pets and human health. These forms of algae can produce both acute and chronic toxins. The acute […]
Lakes and ponds are the lowest point in the watershed and over time can fill in with deposits of rich organic sediments. Over time, these sediments are an accumulation of dead aquatic weed and algae growth, fish and other organisms and become a sink for nutrients that can cycle back to the water column and […]
For decades we have known that providing dissolved oxygen to the lower layer of lakes can improve water quality. Lakes can stratify thermally in the spring and summer months isolating the lower layer from the atmosphere. When that happens, aerobic bacteria can consume the dissolved oxygen that is trapped there in short order and that […]
Cattails and bulrush communities can be a beneficial component of your lake or pond ecology. When left unchecked however, they can form dense monocultures that produced excessive amounts of plant biomass each fall. This biomass if left unchecked will begin to fill in the lake and if left alone too long can result in needing […]
Aquatechnex has an active lake mapping program that can benefit lake managers in a number of ways. A bathymetry map allows you to understand the volume of water, the shape of the lake bottom and locate any hazards to navigation such as shallow bars. An aquatic plant biovolume map can show you the the shapes […]
Aquatechnex biologists have deployed the first of many algae monitoring buoys for our clients in Southern California. This system measures a number of water quality parameters and reports via onboard cellular system every 15 minutes. Two of the key parameters measured are Chlorophyll a with provides a measure of algae biomass and Phycocyanin which is […]
Eurasian Milfoil has plagued Seattle area waterways for decades. Our team at Aquatechnex has successfully dealt with this invasive aquatic weed for a number of years under permits from the Washington Department of Ecology. There are a number of legacy aquatic herbicides that are selective for Eurasian Milfoil, they can target that plant while not […]
