Lakes and ponds are consistently inundated with eroded sediment and debris such as branches, leaves, lawn clippings, trash, and other detritus that create bottom muck containing highly concentrated nutrients as they decompose. Over time, muck levels can increase, reducing the overall depth and volume of the waterbody. Excessive build-up may lead to a host of problems during the growing season, including flooding, depleted dissolved oxygen levels, water murkiness, bad odors, fish kills, and increased weed and algae infestations.
It is possible to physically remove build-up using mechanical solutions like hydro-raking and dredging. Hydro-raking is often used for “spot treatments” in areas with disproportionate materials, such as stormwater pipes and dock areas. A hydro-rake is essentially a floating barge with a rake attachment that can remove up to 500 pounds of decomposing material in each scoop and deposit it on the shore for physical removal or repurposing during shoreline restoration projects.
