Hydro-Ranking & Sediment Removal

Hydro-Ranking & Sediment Removal

Hydro-raking (mechanical raking) is a widely used and effective technique for selective removal of nuisance, rooted vegetation. The hydro-rake is also used to clear accumulations of unconsolidated bottom sediment and debris (i.e. decaying leaves, peat, etc.). Its ability to effectively remove all organic debris from the bottom of a pond make it an ideal choice for routine maintenance that will help to prolong or prevent the need for future dredging. Removing plants and debris will help to reduce the overall nutrient load, minimizing common water quality issues like low dissolved oxygen, foul odors and nuisance algae blooms.


Advantages of Hydro-Raking:

  • Removes plants and debris at the sediment-water interface.
  • Operates in water depths ranging from 18 inches to 10 feet.
  • Removes plants and roots systems, as well as decaying organic matter, soft sediment and debris.
  • Provides anywhere from one to three years or longer of nuisance plant control through only one service, depending on conditions.
  • Clears selective areas including beaches as well as boating and fishing lanes.
  • Offers an environmentally friendly solution with no water use restrictions, since chemicals are not used.
  • Helps preserve shoreline landscapes.
  • Acts as a budget-friendly alternative to traditional dredging.


What is a Hydro-Rake?

The hydro-rake can best be described as a floating barge upon which is mounted a backhoe with several different size and functioning rake attachments. The hydro-rake can operate in water as shallow as 1.0 -1.5 feet and can remove nuisance vegetation and bottom debris from water depths ranging from 18 inches to 10 feet. Duration of nuisance plant control varies, but is typically “summer long” for submersed species such as water milfoil (Myriophyllum sp.) to 2-3 years or longer for plants with well-developed root systems (i.e. waterlilies, cattails, etc.).

Is Hydro-Raking the Right Solution for My Lake or Stormwater Pond?

The hydro-rake works from the water and can therefore access coves and shoreline areas otherwise inaccessible to conventional machinery. Damage to valuable shoreline habitat and waterfront property are avoided with the hydro-rake. The hydro-rake deposits each rake full (maximum 500 lbs.) of material directly on-shore. Where travel distances for shoreline off-loading are excessive or access is limited, Aquatic Management Services LLC. can provide a Harvester/Transporter vessel to work with the hydro-rake. Upland disposal of hydro-raked material may either be handled by the client or Aquatic Management Services LLC. can provide optional trucking and disposal services.
