Stormwater Pond Maintenance Checklist

Keeping your stormwater pond properly maintained is essential for preventing flooding, managing runoff, and staying compliant with local regulations. Stormwater ponds – also known as retention ponds, detention ponds, catchment basins, and stormwater basins – are crucial for filtering pollutants and controlling stormwater flow. Without regular maintenance, these systems can become ineffective, leading to costly damage and regulatory violations.

Use this stormwater pond maintenance checklist to keep your system functioning efficiently throughout the year.

After Every Significant Rainfall Event (More than 1″ in 24 Hours)

• Remove litter and debris that may obstruct the pond’s inlets or outlets.
• Inspect for new points of erosion and address them promptly.
• Check water clarity and look for signs of unusual sediment accumulation.

Spring Stormwater Pond Maintenance

• Inspect pond banks for signs of erosion after winter freeze-thaw cycles.
• Remove dead vegetation and any accumulated organic debris.
• Assess any damage to control structures, spillways, or outlet pipes from winter storms.
• Ensure required signage and safety features (such as fencing and gates) are in good condition.
• Plan for upcoming inspections and maintenance.

Summer Stormwater Pond Maintenance

• Ensure the pond, including spillways, is accessible for inspectors and maintenance crews.
• Check that all required signage remains visible.
• Confirm that any required gating is functioning properly.
• Remove invasive plant species to maintain healthy vegetation around the pond.
• Schedule regular mowing around the pond at least once per month.
• Budget for next year’s maintenance expenses to secure approvals in the fall.
• Schedule fall cleanup to prevent organic buildup.
• Ensure pet waste receptacles are available and maintained (if applicable).
• Clear debris and trash from impervious surfaces (parking lots, roads, walkways).

Fall Stormwater Pond Maintenance

• Conduct a thorough inspection or partner with a professional before winter to identify any structural issues and assess pond readiness for cold conditions.
• Remove excess leaves, branches, and debris to prevent clogging and water stagnation.
• Ensure stormwater outlets are free of obstructions before heavy seasonal rainfall begins.
• Stabilize eroded areas before winter weather exacerbates the damage.
• Trim back any overgrown vegetation that could impact water flow.

Winter Stormwater Pond Maintenance

• Monitor pond for ice buildup that could impact water flow and infrastructure.
• Ensure inlets and outlets remain clear of debris and ice blockages.
• Check for damage caused by freeze-thaw cycles.
• Conduct periodic visual inspections when safe to do so.
• Plan ahead for upcoming spring maintenance tasks.

Why Regular Stormwater Pond Maintenance Matters

Neglecting stormwater pond maintenance can lead to serious issues, including:

• Localized Flooding – Without proper water flow management, stormwater ponds can overflow, causing property damage and safety hazards.
• Water Pollution – Unmaintained ponds allow pollutants from stormwater runoff to enter nearby waterways, harming ecosystems and water quality.
• Soil Erosion – Runoff from impervious surfaces accelerates erosion, which can damage infrastructure and reduce the pond’s effectiveness.
• Legal and Regulatory Consequences – Local authorities enforce strict stormwater regulations. Failure to maintain your pond can result in notices of violation (NOVs), fines, and costly remediation requirements.
