As the Toxic Algae Season Starts, Let’s Remember We have a Solution

Anderson Lake in Jefferson County is suffering from it’s annual closure due to toxic algae blooms.  Cyanobacteria or Blue Green Algae have plagued this lake for decades and it is seldom safe to use this waterbody.

There are a growing number of lakes we have restored using phosphorus sequestration technologies such as Phoslock.  These technologies target and tie up phosphorus in the water column, making algae blooms improbable due to the lack of the key nutrient they need to survive.

This link takes you to a story National Public Radio did on one of our projects last summer.  This lake remains problem free in 2014


EPA Rule Change Could Cost Thousands, Please Read

EPA’s and the Army Corps of Engineer’s proposed rule would expand Clean Water Act jurisdiction to almost all waters in the United States, impacting how communities and landowners manage their public and private property using pesticide and fertilizer products.  Landowners will be subject to CWA provisions for permitting and will be vulnerable to citizen lawsuits challenging their ability to manage their own property.  Professionals making pesticide and fertilizer applications to turf and ornamental plants, golf courses, and to manage invasive and noxious terrestrial and aquatic weeds will also be impacted as will those making public health applications to control ticks and mosquitoes.   The rule was published in the Federal Register April 21, and there is a 90-day comment period until July 21, 2014.  Your voice is important in this process, and we are asking you to support our request for a 90-day comment period extension.

Experimental Lakes Area Needs Your Help

One of the premier research facilities in the world is the Experimental Lakes Area or ELA in Northwest Ontario.  This facility for 45 years was home to some of the cutting edge lake management research performed in the world.  The facility has a number of large lake systems where scientists can try different real world experiments and learn how lakes respond to different management approaches.

This was a federally funded research facility and it lost that funding s short time ago.  Luckily in the short term, Canadian Provincial Governments have stepped up and work will go on there this summer and potentially beyond.  They are in need of support however, what’s learned here goes well beyond Canada and helps us all.

They have set up two web sites that are worth a view.  The first is www.saveela.org

This link gives a good overview of the history and background.

The second is for contributions, if everyone kicks in a little bit you would be surprised how far that can go.   https://www.indiegogo.com/projects/world-s-leading-freshwater-research-facility-the-ela-needs-your-support#home

The Canyon Lake Newspaper has published a good article on our treatment program to sequester phosphorus and help improve water quality.  The article can be viewed at http://fridayflyer.com/2014/04/18/alum-treatments-proving-effective-in-lake-clarity



New Phoslock Case Study, Laguna Niguel

Aquatechnex has published a new case study highlighting the work we did at Laguna Niguel Lake this past year.  This lake has long suffered with excessive cyanobacteria blooms that have impacted the use of the park and the concessionaire’s operations.  This case study highlights our monitoring and the development of a Phoslock treatment program to target and sequester phosphorus in the water column and lake sediments.  This application was made in May of 2013 and has provided a dramatic improvement in conditions at the lake.

Canyon Lake TMDL Project Starting to Show Results

Aquatechnex biologists have been working under a contract for 2013-2015 to target and remove phosphorus from Canyon Lake in Southern California.  Canyon Lake is a 400 acre reservoir and recreational facility and has been impair by high levels of algae growth.  This resulted in the State setting targets to reduce phosphorus availability in the lake.  Algae are single celled organisms and have to obtain the nutrients they need from the water column.  Removing phosphorus reduces the carrying capacity of the lake to produce algae.

The first two of five planned treatments have been performed on the lake.  While phosphorus numbers have been coming down, the results in terms of water clarity are starting to appear.

Flowering Rush Symposium Presentations Available Here

This past February, the Rocky Mountain Invasive Plant Council hosted a Flowering Rush Symposium as part of their program in Spokane, WA.  Flowering Rush is rapidly colonizing portions of river systems in the Pacific Northwest and control of this species is not yet well understood.  This day long seminar provides excellent background and results of work to date on this problem species that we are going to see more of as time goes on.  Aquatechnex biologists have been involved in the management of this noxious weed in Silver Lake, Washington and Lake Pend Oreille, Idaho.  We are also tasked with surveying for it and other invasive species on portions of the Columbia River.

For more information and all of the presentations at this symposium go to this link.  http://www.wrpmc.ucdavis.edu/Research/Invasive_weeds.html


Kyle Langan Qualifies as Certified Lake Manager (CLM)

Aquatechnex biologist Kyle Langan has completed the certification process of the North American Lake Management Society (www.nalms.org) as a Certified Lake Manager.

From the NALMS web site:

The North American Lake Management Society’s mission is to forge partnerships among citizens, scientists, and professionals to foster the management and protection of lakes and reservoirs for today and tomorrow.

The Certified Lake Manager (CLM) and Certified Lake Professional (CLP) program has been established to aid this mission through the identification of individuals who have exceptional training and experience in lake management, thereby establishing themselves as valuable participants in the mission of NALMS.

A lake manager or professional is a person who is directly involved in the comprehensive management of a pond, lake, reservoir or other bodies of water and its watershed and makes decisions which affect the quality and uses of the body of water. This person will be primarily responsible for implementing appropriate measures and/or for making recommendations to the governing management body.

A certified lake manager or certified lake professional is an individual who has satisfied the NALMS requirements intended to properly prepare that person to perform the above duties with maximum competence. CLMs/ CLPs establish themselves as both knowledgeable and experienced professionals by meeting the requirements.

Kyle joins Terry McNabb as the second CLM qualified professional on our staff.  Kyle is responsible for managing a number of lake systems in Southwest Washington and Oregon.
