Aquatechnex Opens Montana Office

Noxon Reservoir Eurasian Milfoil Treatment

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 by these water quality issues.

Montana Eurasian Milfoil and Montana Flowering Rush infestations can be controlled by programs we develop.  Our team has successfully removed Eurasian Milfoil from plots in the Clark Fork River using ProcellaCOR herbicide technology.  This work was performed in the summer of 2019, and evaluation by the State of Montana in the summer of 2020 found that no milfoil remained in these treatment plots.  This technology is available only through Pro Certified Applicators approved by SePRO Corporation.  More information can be found at

Many lakes in Montana are experiencing toxic HAB conditions, a map of those waterbodies that have or are experiencing toxic events can be viewed at

Montana Toxic Algae Blooms can be mitigated in a number of ways by our team.  We have application technologies that will remove the threat.  We also have programs that utilize phosphorus precipitation such as Phoslock to mitigate phosphorus pollution that drives these blooms.

Excellent video of our American Lake Eurasian Milfoil Control Program

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 and implemented a treatment program that used Procellacor herbicide to restore over 160 acre of the water body.  Survey work throughout the 2020 season showed 99% control lake wide.

Excellent Video on Vancouver Lake Eurasian Milfoil Control Program

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 program to target and remove this invasive weed from over 700 acres of the lake that were heavily infested.  Follow up surveys by the Department of Fish and Wildlife have determined that this project was highly successful.

First Full Year with Procellacor Herbicide in the Books

In mid summer of 2019, the Washington Department of Ecology added Procellacor herbicide to our state’s permit and to date the results have been stunning.  We have delivered close to 100 percent control in all cases where we have applied it.

Procellacor is a product that was registered by the US EPA as a reduced risk herbicide.  It can be applied to lakes, rivers and reservoirs without any restriction on the use of treated water for Potable Supply, Swimming, Fishing or irrigating turf grass (there are short irrigation restrictions for some ornamental species).  It also has the fastest plant accumulation factor or uptake of any aquatic herbicide we have in the tool box.

In our region the primary invasive aquatic weeds we fight is Eurasian Milfoil or hybrid strains of that species.  Procellacor is becoming our go to technology for combating this plant.  Procellacor is selective for milfoils, it is systemic and will control the entire plant and it provides long term control.

In conjunction with SePRO Corporation Procellacor can come with a three year warranty and payment program as well so you have the opportunity to do more work in year one and stretch payments over three seasons.

Procellacor is available through Pro Certified Applicators such as our team.  For more information on this product and the Pro Certification Process, you may visit


Ian Cormican Awarded SePRO Preferred Applicator of the Year

SePRO President Bill Cullpepper and Aquatic Manager Sam Barrick award Aquatechnex Ian Cormican the Applicator of the Year Award

SePRO President Bill Cullpepper and Aquatic Manager Sam Barrick award Aquatechnex Ian Cormican the Applicator of the Year Award

This past week out team met with the top aquatic plant management firm from across the United States at the SePRO Preferred Applicator Seminar held this year in St. Thomas, VI.  SePRO is a life science company that has invested to bring to market a number of the key tools we need to manage invasive aquatic plants and phosphorus pollution.

During this meeting, SePRO recognized Dr. Lars Anderson, retired from the USDA ARS Aquatic Plant Management Research Program with a Lifetime Achievement Award.  Lars worked on invasive aquatic weed and marine algae issues from his office in Davis California for the past three decades.  Bill Cullpepper credited him with the idea to develop immunoassay to rapidly measure herbicide levels in lakes and thereby more accurately dose areas impacted by invasive aquatic weed growth.

Aquatechnex biologists Kyle Langan and Adam Kleven were awarded “Seeing is Believing” award for documenting two projects that used new technologies from SePRO to remove phosphorus pollution from our clients lakes limiting eutrophication.

The highlight of the evening for us was their selection from over 150 of the top aquatic plant management experts in the United States of Ian Cormican, our Southern California Regional Manager.  Ian was presented with the 2012 Applicator of the Year award for leadership in the field of aquatic plant management.  Thanks to SePRO and congratulations to Ian for work well done.

McDowell Lake Eurasian Milfoil Control Successful

McDowell Lake is located in the Little Pend Oreille National Wildlife Refuge just east of Coville, Washington.  This lake was revered by fly fishers throughout the northwest as one of our premier fishing waters.  In the mid 2000’s, the invasive weed Eurasian Milfoil was introduced to the systems.  This noxious weed rapidly filled the water column lake wide and choked off access to the fishery.  As this pristine water was walk in walk out, fishers with tubes could not move around the lake through the thick growth.

The US Fish and Wildlife Service turned to Aquatechnex to help solve this problem.  Aquatechnex has a long history of providing programs that can eradicate this invasive species from a water body.  We designed and delivered a program that utilized timed treatments of Sonar Aquatic Herbicide in the new Precision Release Pellet technology in 2006. The key to this success is being able to maintain low doses of Sonar in contact with the target vegetation for an extended period of time.  The Precision Release Pellet is designed to help accomplish that goal.

In the summer of 2007 and 2008, Aquatechnex divers have surveyed the lake and determined that the system remains milfoil free.  This lake is added to the list of lake systems we have successfully eradicated Eurasian Milfoil from using our technology.  In addition, as is generally the case, native aquatic plants are thriving in the nitch that used to be occupied by the noxious invader.

Aquatechnex Capitol Lake Project featured in IWAC Article

In 2001, the State of Washington came to our company to help solve a Eurasian Milfoil problem in Capitol Lake.  This lake is the reflecting basin for the state capitol and is the focal point for the Community.  The state maintains park facilities around the lake.  Aquatechnex developed an Integrated Aquatic Vegetation Management Plan for the State and implemented it with a successful treatment using Renovate Herbicide in 2004.  The lake has been maintained since that time by surveys and diver removal of those plants found. 

The Invasive Weed Awareness Coalition recently published a fact sheet on this project.  You can view it at the link below to see that story.

The Economic Impact of Eurasian Milfoil

Over the past few years, the Houghton Lake (Michigan) residents have implemented a program to combat an extensive infestation of Eurasian Milfoil.  This shallow 20,000 acre lake was completely covered with this invasive aquatic weed in the early 2000’s.  Aquatechnex biologists were invited to participate in the Corps of Engineers Program to evaluate and design a solution to this problem.  SePRO Corporation took the lead in removing this weed and allowing the native plant communities to recover.  During this process, they were able to document the impact of this plant and it’s control on the use of the lake, tourism and property values.  This work has been published by SePRO and is available at this link.  It is a good read, give it a look.

Land and Water Magazine Publishes Article About Aquatechnex N. Idaho Eurasian Milfoil Programs

Land and Water Magazine ( is the leading resource for water restoration information.  The magazine is published six times per year and distributed nationally.  In July, Land and Water came to Aquatechnex after learning of our successful Eurasian Milfoil Control Program on Lake Pend Oreille and the Pend Oreille River in North Idaho.  During the summer of 2006, our firm was selected to target this infestation with the largest control program ever implemented in the Western United States.  The article is available on our web site from the front page along with video footage from local television coverage.  To read the article, click here.

Eurasian Milfoil kills Washington Man

Eurasian Milfoil infestations in western water bodies continue to claim lives.  Early this summer, one of our lakes saw a four year old lost in milfoil at a county beach.  While his parents understood he was under, they could not find him in time in the thick milfoil.  This past week the milfoil in the Columbia River claims a 22 year old male.   Over this past few years, anti herbicide groups have attempted to stop the use of a number of key aquatic herbicides used to combat this weed.  While these products are fully cleared by the US EPA to be used in lakes without any harmful results, the claims of these groups do sometimes find an ear.  It’s important to note that there are no reports of adverse effects of these products on humans, but the milfoil itself continues to kill where not treated.
