Aquatechnex announces Montana Office

Aquatechnex has opened an office in Missoula, MT to serve the needs of the region.

There has been a significant expansion of Eurasian Milfoil in Montana in recent years.  Aquatechnex has a long history of being able to restore lake and river systems impacted by this invasive aquatic weed.  One of the key tools we have for Montana Milfoil Control is ProcellaCOR herbicide.  This technology will selectively target this plant, it will translocate and control the entire plant and will not impact native aquatic plants allowing them to recover.  ProcellaCOR is available through SePRO Pro Certified Applicators and our team has qualified as such.  We are the only Pro Certified Applicator based in Montana and look forward to helping the deal with this expanding problem Pro Certified ProcellaCOR Applicator.

Another problem facing Montana waters are toxic algae blooms.  Many species of cyanobacteria produce acute toxins that can impact wildlife, pets and human health.  They are also directly linked to longer term chronic diseases such as ALS.  Harmful Algae Blooms or HAB are nutrient driven.  As phosphorus pollution increases, HAB species have a competitive advantage.  The Montana State HAB map is shown here State of Montana HAB Map

Montana Harmful Algae Blooms can be targeted and reduced.  Aquatechnex biologists have a number of US EPA registered tools that can treat and mitigate the bloom condition.  We also are expert in the use of Phoslock to remove phosphorus and reduce the carrying capacity of the lake to produce HAB blooms.  We use nanobubble technology to target blooms in smaller lake systems effectively.  We can also install remote HAB monitoring buoys that give us a heads up when conditions are approaching treatment thresholds.

Is “Bio-Dredging” a thing? Yes it can be

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 fuel additional growth degrading water quality.

Removing this organic build up is often required to restore water quality and to add depth to the pond.  Conventional dredging can be problematic in urban settings.  There often is not room to pump dredge spoils in a HOA or golf course pond environment.

Our mapping systems can determine lake sediment composition, the lighter colored areas show organic sediment accumulation

One solution is to enhance the natural processes to digest this organic matter and increase water depth.  This can be accomplished by our biologists using a combination of Nanobubble Technology and the addition of Probiotic natural bacteria cultures.

A nanobubble generator deployed to lake to increase sediment oxygen levels

Dissolved oxygen levels in organic lake sediments is generally very low to zero.  Dissolved Oxygen is key to the success of aerobic digestion of these organic sediments.

Nanobubble generators deliver high levels of dissolved oxygen right to the sediment interface and the interstitial waters within the sediments.  These generators pump water from the lake though the nanobubble generator and inject nanobubble rich water back into the lake.  Nanobubbles are very small, on the molecular level, and they are negatively buoyant and sink to and into the sediment layer throughout the lake.  They then attach and burst delivering dissolved oxygen right into the sediments.

Sediment oxygen levels rise dramatically after installation of nanobubble generator and increase digestion of organic sediments

We install either a temporary or permanent Nanobubble Generator at the lake sized to the volume of the lake

We then apply Naturalake BioSciences MuckBiotics pellets evenly across the targeted area monthly.  MuckBiotics pellets saturate the sediment layer with rare earth stimulants and a broad spectrum of natural aerobic bacterial cultures.  This accelerates the digestion of organic matter

MuckBiotics pellets are then applied monthly to increase the speed of sediment digestion.

We measure the reduction in sediment depths over time to document the recovery of the lake from the impact of accumulated sediments.  This process will not reduce deposition of sand or soils, but can greatly benefit the lake and avoid having to physically dredge organic sediments to restore water depth and lake health.

Our biologists can design a program that meets your needs.  Please reach out if your pond needs remediation of organic sediments.

We also work with conventional dredging equipment when this approach isn’t suitable for your situation.

Lake Mapping

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 and location of aquatic plant communities as well as the percent of the water column that is occupied by this growth.  This can assist in lake management planning and aquatic plant management operations.  It can also be used to track response to treatment strategies used to control these species.  A bottom hardness map is useful in determining organic sediment accumulation in your lakes and can help design dredging or sediment reduction strategies.

This work is done using hydro-acoustic mapping technologies.  Our survey boats travel transects across the lake collecting this information.  The data is processed and map generated.

If your interested in getting your lake mapped we would like to help.  Please get in touch.

Aquatechnex Completes Loon Lake Bathymetry Mapping

Loon Lake is located in Washington State just north of Spokane.  Bathymetry maps are something that has been available for Washington Lakes, the State conducted a survey of the majority of the larger lakes in the late 1960’s.  Forty plus years is a long time however and changes in the watershed can contribute sediments that fill lakes in.  The Loon Lake Community has formed a lake management district (LMD) and getting current bathymetry to help them manage this resource was key.

Aquatechnex biologists were able to deploy the Cabela’s Lake Mapping System to Loon Lake in October of this year.  Data collection on this 1106 acre lake took approximately five days to complete, the Cabela’s system records a GPS point and depth location every 2 seconds and over 120,000 sounding points were collected as part of this process.  This data was shipped to Cabela’s Geographers and they developed extremely accurate bathymetry and 3D models of the lake.  The project was completed in under three weeks from start to finish and the lake residents now have an excellent system to use in their ongoing lake management program.
