Lake Restoration

Diagnosis and remediation of degraded urban lakes, from nutrient control to ecosystem recovery.

Overview

Lake Restoration

Urban lakes concentrate the pressures of the cities around them: stormwater runoff, wastewater inflows, and sediment loading all drive eutrophication, algal blooms, and loss of dissolved oxygen. Lake restoration addresses these problems at their source and within the lake itself, with the goal of returning the water body to a healthy, self-sustaining state.

Effective restoration begins with a diagnostic study, mapping inflows, nutrient budgets, sediment quality, and the biological community. Interventions are then sequenced: controlling external pollution loads first, followed by in-lake measures such as sediment management, aeration, aquatic vegetation re-establishment, and biomanipulation to rebuild a balanced food web.

Because lakes respond slowly, restoration programmes are planned over years with clear monitoring milestones. Success is measured not only in water clarity but in the return of biodiversity and the lake's renewed capacity to serve recreation, flood storage, and urban climate regulation.

The Challenge

The Challenge

Urban lakes concentrate the pressures of their cities: stormwater runoff, wastewater inflows and sediment loading drive eutrophication, algal blooms and oxygen depletion. Symptoms are visible, green water, odour, fish kills, but the causes lie upstream and in the sediment, and treating symptoms alone never lasts.

Our Approach

Our Approach

  • Start with diagnosis: inflows, nutrient budgets, sediment quality, biology
  • Control pollution at its sources before intervening in the lake
  • Apply in-lake measures matched to the diagnosed problems
  • Monitor recovery and adapt the plan to what the data shows
