Improving Water Clarity

Murky or cloudy water is often a sign of suspended sediment due to erosion, pollution, and stagnation that’s hospitable to nuisance mosquitoes, weeds, and “rotten egg” like odors. These signs indicate muck build-up at the bottom of the waterbody. Bottom muck accumulates as a result of inhibited decomposition of materials like plants, algae, and other organic substances like lawn clippings and fertilizers that have washed in over time. It can also be caused by the presence of invasive species like armored catfish, which burrow into shorelines to breed and lay eggs. Oxygen-rich waterbodies are capable of efficiently processing this sludge, but when oxygen is deficient, muck can accumulate faster than it can be broken down.

There are many solutions to increase dissolved oxygen levels in your lake or pond. Floating fountains circulate and aerate the water near the surface while submersed aerators integrate oxygen and movement from bottom to top. Though effective at restoring balance throughout the water column by creating conditions that are less hospitable to plant and algae growth, these types of solutions are limited at targeting muck directly. However, exciting new innovations like Oxygen Saturation Technology (OST) are capable of injecting pure oxygen directly into muck and sludge to expedite its degradation. OST can also distribute oxygen into specific areas in the waterbody for highly targeted oxygen saturation in spaces that need it most.

Likewise, steps should be taken to prevent future erosion around the waterbody. Introducing native, deep-rooted buffer plants can help contain the sediment and filter the polluted runoff that flows into the water during rainstorms. More significantly weakened banks can be stabilized using modern shoreline restoration techniques. A patented knitted mesh solution called SOX Erosion Solutions completely reshapes and anchors the sediment for long-lasting durability. Once in place, the SOX can be planted with sod and beautiful beneficial plants for seamless integration into the surrounding property.

In many cases, shoreline restoration services are paired with hydro-raking. A hydro-rake is a floating barge equipped with a backhoe that physically scoops hundreds of pounds of muck and debris from the bottom and deposits it on shore for reshaping or removal. Before hydro-raking can take place, Aquatic Specialists often complete bathymetric studies. Bathymetry is a process of mapping the bottom of a lake or pond to precisely identify its unique contours and determine the areas most affected by sediment build-up. 

Water murkiness is not always a result of muck or suspended sediment. Water can also appear murky due to the presence of planktonic algae, which are microscopic organisms that create visually dense blooms on the water’s surface. Planktonic algae are known to appear in blue, green, brown, and red colors, which are most apparent around the shoreline. Similar to bottom muck, the high concentrations of these algae are typically a result of poor oxygen concentrations and high levels of nutrient pollution.

Aeration is helpful to prevent the accumulation of undesirable blooms, but this solution should also be supported by services like nutrient remediation. When strategically applied to a lake or pond, products like Phoslock and Alum bind to excess nutrients to prevent them from fueling the growth of nuisance algae. Because some species of planktonic algae produce dangerous toxins that are known to harm humans and kill dogs and wildlife, algaecide applications may also be used to swiftly eradicate the blooms.
