The Algae Triangle: Managing Nuisance Pond Algae Without Algaecides

by: SOLitude Lake Management   |   May 14, 2018

Algae Triangle

Written by Industry Expert Gavin Ferris, Ecologist 

I frequently use herbicides and algaecides in my line of work. Having attended college and graduate school to be an Ecologist, it isn’t something I thought I would do very often, but with the frequency of environmental problems that involve invasive flora, nuisance aquatic weeds and potentially-toxic algae, EPA-registered herbicides and algaecides are an invaluable tool. There are, however, times when their use is impractical, imprudent, illegal or impossible. Maybe the HOA or property manager prefers that herbicides not be applied to nearby waters. Perhaps the regulatory bodies in a given area aren’t permitting the use of certain products. Whatever the reason, sometimes this option just isn’t on the table. But how do we effectively manage algae and aquatic weeds without herbicides and algaecides?

I employ a simple concept that I call the algae triangle, though it works for all forms of vegetation.

Harmful Algal Blooms

In recent years, cities have made headlines for outbreaks of toxins stemming from Harmful Algal Blooms (HABs) in lakes, stormwater ponds and reservoirs. In addition to being unsightly, these blooms and the neuro-toxins they can produce are suspected to have links to diseases like ALS, Parkinson’s and Alzheimer’s. They are also responsible for various taste and odor producing compounds that plague many of our drinking water reservoirs. SOLitude Lake Management, an environmental firm dedicated to improving lives through ecological education, is hosting a free informational webinar focused on methods to properly identify toxic algal blooms and sustainable strategies to prevent them from developing in our community waterbodies this summer.

Case Study: Managing Invasive Water Soldier in a Canadian Waterway

by: SOLitude Lake Management   |   Apr 09, 2018

Water Soldier

Written by Industry Expert Glenn Sullivan, Environmental Scientist

The only known Water Soldier infestation in North America...

Canada’s Trent-Severn Waterway provides a link between Lake Ontario in the southeast and Georgian Bay in the northwest, allowing boat navigation for its entire 240- mile length through a system of rivers and lakes, and 41 locks. Water Soldier (Stratoides aloides), an invasive aquatic plant that forms impenetrable mats on the water surface, infested an area of approximately 700 acres within the Trent-Severn Waterway. The infestation was first reported in the Trent River, in September of 2008, and is considered the only known Water Soldier infestation in all of North America.

Have You Considered Hydro-raking as an Aquatic Management Tool?

Hydro-raking

Written by Industry Expert Emily Walsh, Environmental Scientist 

If you own or manage a lake or pond, you’ve likely heard of hydro-raking as a unique management tool utilized by aquatic professionals to remove aquatic vegetation. A hydro-rake is essentially a floating barge supporting a mounted backhoe and rake attachment that can remove up to 500 pounds of lake and pond muck, aquatic plant material and organic debris in a single scoop.

Duckweed

Written by Industry Expert Josh Perry, Environmental Scientist

Do you know what costs homeowner’s associations, small communities and government agencies over 120 billion dollars annually? The answer is invasive species. Far beyond the monetary costs, invasive species create unsightly, unbalanced and unhealthy aquatic ecosystems. Unfortunately, human activity is responsible for most infestations. Whether you’re a part of a lake community, live near a stormwater pond or even own a decorative backyard water garden, we all play pivotal roles in spreading—but also preventing—invasive aquatic species.

Nuisance Species Highlight: Bladderwort

by: SOLitude Lake Management   |   Feb 22, 2018

Nuisance Plant Management

Bladderwort (Utricularia spp.) is a genus of carnivorous aquatic plants consisting of more than 200 species. The submersed free-floating plants utilize bladder-like traps (0.2mm-1.2cm) to capture small prey, including mosquito larvae. Hundreds of traps cover the plant’s 4- to 10-inch stem, which can be topped by yellow or lavender flowers.

Despite the beauty, recreational space and natural wildlife habitats that our nearby waterbodies provide, lakes and ponds are often plagued by various ailments that can detract from the aesthetics, health, and functionality of their aquatic ecosystems. The following are a few responses to common questions often asked by those interested in lake and pond management.

Why is our pond green?
Without proper water quality testing and analysis, it can be difficult to determine the exact causes behind a green pond. The green you’re seeing may be algae. While algae look similar to some aquatic plants,

Combating Invasive Species While Protecting Native Plants Downstream

FanwortAgawam Mill Pond, located in Wareham, Massachusetts, is a 150-acre waterbody owned by the Commonwealth of Massachusetts and is managed by the MA Division of Fish and Wildlife (MA DFG). It is used heavily for recreational activities, such as boating, fishing and swimming, and supports moderate residential development. The pond has an average depth of six to eight feet with a maximum depth of twelve feet; therefore, emergent and submerged aquatic vegetation has the capability to flourish, rapidly expanding into dense colonies. Currently, the invasive, non-indigenous submersed vegetation (fanwort and variable watermilfoil) has inundated the pond causing a decline in water quality and has severely limited recreational activities for residents and guests.

The Nuts and Bolts—and Bubbles—of Lake and Pond Aeration

AS SEEN IN CAI ROCKY MOUNTAIN: Written by Industry Expert Shannon Junior, Aquatic Ecologist and Senior Business Development Consultant

CAI Rocky MountainThere are few events that can occur in a community pond that cause the amount of anxiety and uproar among the residents as a fish kill. Sure, we get plenty of calls about lake and pond algae blooms and clogged fountains and excessive trash, but nothing creates the level of panic that ensues when there are dead fish floating on the surface of the water. Many residents become concerned that there may have been a toxic spill or illegal dumping incident, or they think that the landscaping company must have used something on the surrounding property that killed the fish. In reality though, most fish kills occur not because of a poisonous substance, but because of low dissolved oxygen conditions in the water.
