Plant and Algae Control for Lakes, Ponds and More

The plants and algae in your ponds, lakes or other waterbodies are a critical part of keeping its water system balanced – helping improve overall water quality, provide oxygen, enhance fish and wildlife habitats, and create shorelines and littoral areas that serve as filters for runoff.

Clarke’s aquatic plant services help control nuisance species and overgrowth, creating a healthy body of water for the entire community.

Clarke’s Approach to Plant and Algae Management for Long-Term Control

1. Inspection and Assessment: The Clarke team conducts a visual inspection and identification of plants and algae, including basic water quality monitoring checks. Surveying and mapping of the water body may also be needed, depending on its size and unique characteristics.

2. Management Plan Design: Once the inspection and assessment are completed, a specific management program for your lake or pond can be designed, including recommendations for achieving long-term enhanced water quality.

Healthy Plants Make for a Healthy Waterbody

The breadth of ever-changing factors acting on waterbodies – such as recreational use, weather, run-off, nutrients and more – makes maintaining the plants and algae within your waterbodies challenging. Without having a tailored ongoing aquatic plant management plan in place, it is all too easy for these factors to go unnoticed, resulting in potentially disastrous and expensive outcomes.

Clarke’s team of experts brings decades of experience to each water body, working to meet the established goals and mitigate harmful outside effects on the entire water system.
