Shropshire Lake Cleaning and Duckweed Dredging and Removal

Duck weed is every lake owner's nightmare. Duckweed is a plant that floats on water. It is a tiny, green, leafy plant similar in shape and texture to a lily pad. Each piece is no larger than 5 mm, yet it can quickly take over any body of standing water.

Duckweed production is fairly complex but in a nutshell duckweed originates from seeds dropped by birds in the water. These seeds drop to the bottom of the pond and are held in the silt. The nutrients in the silt and the sun on the water (photosynthesis) results in mass production of duck weed.

Cleaning the lake of duck weed - methods include:

  • Aeration of the bottom of the lake - this circulates the excess sediment from the bottom of the lake but can take many seasons to have an effect and required large and expensive aeration systems


  • Nutrient Reduction - this would involve eliminating the accumulation of nutrients in the pond caused partly by falling leaves. This is not always practical in large bodies of water


  • Addition of fish stocks - Tench love to feed on the nutrients found on the bottom of the pond any easily accessible sources of food such as duckweed floating on the top. As they increase in size as a result they eat more and so on


  • Chemicals - There are chemicals available which claim to eliminate the nutrients and reduce duck weed growth but these are only suitable for smaller bodies of water and where fish are not present. There are natural bacterial products also available but these are not usually cost-effective on larger bodies of water
The methods we employ to clean the lake of duckweed depend on the size of the lake, whether fish are present or not, and the amount of duckweed already on the surface of the water.

In extreme cases, we will firstly dredge the surface of the lake to remove any existing duckweed before any secondary action can be started.
