Ponder These Thoughts - Summer Pond Management Tips

by: SOLitude Lake Management   |   Jul 24, 2017

Floating FountainSOLitude Lake Management wants your lake or pond to be prepared for warm weather. With this in mind, we recommend that you consider the following during the summer months:

• Warm summer weather seems to bring out the best and the worst in ponds. Although pond algae and aquatic weeds seem to be more abundant at this time of year, a year-round maintenance plan is the best way to ensure a healthy pond all year long.

• Reduced flows and warmer water temperatures increase the potential for Harmful Algae Blooms (HABs), which can be a threat to the environment as well as the health of humans, pets and wildlife. If you experience blue-green algae and surface scum or suspect an increase in microscopic algae growth, contact one of our biologists.

The Importance of Lake and Pond Aeration Systems

by: SOLitude Lake Management   |   Jul 18, 2017

Written by Industry Expert Greg Blackham, Aquatic Specialist

Floating FountainChoosing the correct aeration delivery system for your lake or pond is one of the most important decisions you will make for the long-term health and balance of your waterbody. Regardless of how big or small your waterbody is, the goal of an aeration system is to evenly spread an adequate amount of dissolved oxygen throughout the entire water column. Lakes and ponds naturally receive dissolved oxygen from several sources, most notably plant respiration and atmospheric surface mixing. This input of oxygen should be equal to or greater than the demand of the aquatic ecosystem. The entire ecosystem of the water needs that dissolved oxygen, whether at the very bottom of the food chain for microbial decomposition, or at the top for largemouth bass and other predator fish. In most cases, it is discovered that the oxygen supply is lacking due to pond nutrient pollution or other stresses caused by people and land development.

To determine what type of oxygen delivery method or aeration system is appropriate, the waterbody needs to be looked at from several angles. Many online resources recommend aeration systems based on only one or two aspects of the waterbody. To find the best aeration solution, several factors should be considered: 1) overall acreage of the lake or pond, 2) average water depth, 3) maximum water depth, 4) shape of the waterbody, 5) proximity to electricity, 6) desired aesthetics, 7) noise tolerance, 8) water quality. The more information we have, the better we can determine how to spread the dissolved oxygen throughout the entire lake or pond.

How Often Should Water Quality be Tested?

by: SOLitude Lake Management   |   Apr 13, 2017

Written by Industry Expert, Brea Arvidson, Aquatic Biologist

water-quality-aquatics-in-brief-e.jpgHealthy water quality is extremely important for all lakes and ponds, and proactive testing and monitoring is vital when it comes to helping prevent water quality problems in recreational lakes, stormwater ponds and drinking water reservoirs. Lake and pond owners often wait until an algae bloom, fish kill, foul odor or other negative water quality problem occurs before implementing a basic water quality program. This can have dire consequences.

Poor water quality can quickly lead to an unbalanced ecosystem, which not only negatively impacts the ecology and recreational use of a waterbody, but can also affect surrounding waterways. Take the enormous toxic algae bloom in Florida, for example, which originated in Lake Okeechobee in the summer of 2016 and impacted Treasure Coast waterways and beaches; the dangerous cyanobacteria limited boating, fishing and swimming throughout South Florida and posed a serious threat to the health of residents, tourists, pets and wildlife. While a number of unique factors contributed to the development and spread of this harmful algae bloom, it is clear that water quality problems in our lakes and ponds can rapidly turn into ecological nightmares.

Fish Habitat Management: “Cover” Your Waterbody

by: SOLitude Lake Management   |   Feb 09, 2017

Written by Industry Expert Paul Dorsett, Fisheries Biologist and Territory Leader

How to Create a Better Aquatic Habitat for Your Fish

1_Fish Cover e-1.jpgThere’s an old adage that states, “Ninety percent of fish live in ten percent of the water.” This statement has more truth than most realize. Fish move throughout their environment for a variety of reasons including spawning, optimizing their temperature, feeding, and avoiding predators. For “lie in wait” predators and many baitfish species, these movements are mostly relegated to being in or around the desired cover at varying depths. The availability of quality fish cover and the fishes’ desired depths will determine which 10% of the aquatic environment the fish choose to live in at any point in time. Therefore, placement of the right amount of cover at the appropriate depths should be a major objective of a lake or pond owner’s habitat improvement projects.

For the purposes of this article, I’ll limit discussion to the non-living cover that can be placed in a waterbody to provide cover for your fish. The first consideration in choosing cover type is the physical make-up of this cover with respect to its suitability for both forage fish and predator species. Baitfish tend to prefer large dense cover that offers the tight interstitial spaces and volume needed to protect them from predators. Larger predator species, however, prefer less dense cover with larger interstitial spaces that provide them a place to “loaf” while they await prey to make “their last mistake.”

Drinking Water Reservoir Management

by: SOLitude Lake Management   |   Feb 07, 2017

Written by Industry Expert, Shannon Junior, Aquatic Ecologist and Senior Business Development Consultant

Beaver Creek Reservoir 2_After_Crozet VA_ShannonJ_e.jpgWe are fortunate in the United States that our country has the technology and resources to provide clean and palatable drinking water to our citizens. However, the recent catastrophic situations in Flint, Michigan earlier this year and in Lake Erie in 2014 have reminded many Americans that this is a privilege that we should not take for granted. And while the lead crisis in Flint was caused by human negligence and could have been prevented, the ongoing cyanobacteria blooms in Lake Erie are due to a much more complicated process of phosphorus pollution and water quality degradation.

Cyanobacteria were previously identified as blue-green algae due to their ability to photosynthesize, although they are actually prokaryotic and more closely related to bacteria than algae. Now commonly referred to as harmful algae blooms (HABs), cyanobacteria blooms are particularly problematic when they occur in waterbodies that are used as a source for drinking water utilities. Not only do cyanobacteria excrete compounds such as MIB and Geosmin that cause unpleasant tastes and odors in the water, but they also have the potential to produce cyanotoxins that can be harmful to humans, pets and wildlife.

A Success Story: Restoring Fiske Pond Through Mechanical Harvesting

by: SOLitude Lake Management   |   Feb 02, 2017

Written by Industry Experts Jeff Castellani, Director of Mechanical Operations, and Emily Walsh, Environmental Scientist

3_Fisk Pond Harvester_e.jpgFiske Pond is a 67-acre waterbody located in Natick, Massachusetts within the Lake Cochituate sub-basin of the Sudbury River Watershed. Nestled in an urban area outside of Boston, Massachusetts, Fiske Pond was traditionally enjoyed by the community for recreational activities such as fishing and canoeing. Unfortunately, these leisurely activities became increasingly limited due to the dense mat of Water Chestnut (Trapa natans), an invasive aquatic plant that has proliferated since 2004. By 2008, the infestation had established a monoculture covering over 40 of the 67 acres, leading to major biological and recreational concerns. At this time, the Department of Conservation and Recreation (DCR) contacted SOLitude to initiate a management program.

Due to the competitive nature of invasive Water Chestnut, it was decided that mechanical and physical removal, via harvester and hand pulling, was the proper management approach for the removal and eventual eradication of the nuisance aquatic weed from Fiske Pond. Mechanical harvesting was an ideal management option due to the machine’s mobility and capability to remove plants from the water’s surface with minimal disturbance to the sediment below. This option was more attractive than herbicide applications because it removed the plant biomass and prevented the dense mat of vegetation from decaying, releasing nutrients back into the water column and contributing to further eutrophication of the pond.

Utilizing Bathymetry to Budget for Future Repairs and Dredging

by: SOLitude Lake Management   |   Jan 19, 2017

Written by Industry Expert, Kevin Tucker, Chief Executive Officer

If you live in a planned community governed by a Homeowners’ Association (HOA), are part of a lake association, own commercial developments, belong to a golf club, are a member of a recreational club, or you are a board member or manager for any of the above, you are likely familiar with the need to maintain a reserve and replacement budget. In many cases, it is a statutory requirement.

Reserve Studies are a great tool to help prepare stakeholders for significant future repair and replacement expenses. They often uncover items that might not have been top of mind if left unaddressed, but would pose a significant financial risk to the group. In most cases, the Reserve Specialist preparing the report is able to identify very accurate estimates for the expected life of your physical assets, as well as the corresponding costs for making significant repairs or replacing them as their expected life comes to an end.

Pond Management: The Restoration of Cliff Pond, in Brewster, MA

by: SOLitude Lake Management   |   Dec 01, 2016

By Industry Expert Dominic Meringolo, Senior Environmental Engineer and Territory Leader

cliff-pond-restoration-e.jpgCliff Pond, located in Brewster, Massachusetts, is one of the most popular destinations on Cape Cod for water recreation. It also serves as the highlight attraction of Nickerson State Park, a heavily used property which includes a large campground that is often booked solid each summer. Cliff Pond has a surface area of 207 acres and is the deepest pond on Cape Cod with a maximum water depth of about 88 feet. Unfortunately, in the past few years the waterbody has experienced frequent bluegreen algae (cyanobacteria) blooms. Water quality issues have also resulted in a frequent loss of suitable cold-water habitat for what once was a very healthy and productive trout fishery.

Cliff Pond began having problems with nuisance algal blooms in the 1980s, and in the late ‘90s two dog deaths were attributed to algal toxin consumption. In recent years, following the establishment of state guidelines on Harmful Algae Blooms, advisories have been in place restricting use of the pond for contact recreation for most of the summer. Realizing the deteriorating condition of the pond and its impact on recreational use, the state of Massachusetts through its Department of Conservation and Recreation (MA DCR) contracted with SOLitude Lake Management for a comprehensive study in 2014 and 2015.

The Solar Solution: Solar Powered Aeration for Lakes and Ponds

by: SOLitude Lake Management   |   Nov 29, 2016

By Industry Expert Brent Weber, Environmental Scientist and Territory Leader

solar-aeration-pond-management-e.jpgThe list of benefits that an aeration system can provide a lake or pond is endless. Besides helping to enhance fish habitat, improve water quality, reduce algae and remove unwanted nutrients, aeration can also break down unwanted bacteria, help prevent mosquito infestation and remove foul odors from a waterbody—all by circulating the water and adding dissolved oxygen. Sometimes, though, it’s not feasible to install an aeration system in an isolated lake or pond with no economical way to provide a power source. This predicament presents itself in a variety of different areas, including golf course lakes, farm ponds, private waterbodies, and homeowner association stormwater ponds.

Fortunately, there is a solution for those who are unable to get electric power to their lake or pond. Solar aeration systems were introduced to the lake and pond management market about a decade ago, and have made great strides in their overall effectiveness and efficiency over that time. Instead of going through the hassle or expense of running electricity to an area in need, there are now a variety of viable solar powered alternatives available from many different manufacturers. So, that waterbody on “the other side of the property” can now get the proper attention and aeration it needs to help keep it healthy and balanced.
