SMALL POND MANAGEMENT IN THE CITY OF WINTER PARK, FLORIDA

Timothy J. Egan City of Winter Park, Public Works Department, Lakes Division Winter Park, FL

Introduction

The City of Winter Park manages 14 natural lakes and ponds under 20 acres in surface

area.

Water quality, and habitat management issues vary widely from pond to pond,

management activities and techniques must be site specific to maintain ecological pond aesthetics. Problems frequently encountered in small ponds include:

integrity

and and

  • turbidity

  • low dissolved oxygen

  • planktonic algae blooms

  • filamentous algae blooms

  • floating plant infestation

  • exotic plant infestations of the littoral zone

  • exotic animal introductions

  • flooding/high water

Many ponds suffer from two or more of these conditions at any given time.

These

problems are usually caused, or exacerbated by, high nutrient, and organic material loads from storm water runoff. Public access to, and recreational opportunities provided by many small ponds are often limited, making them a low priority for capital expenditures. Even on the most limited access ponds, though, the adjacent property owners, and others that contribute runoff to the pond, pay into the city’s storm water utility. The City of Winter Park is committed to providing the highest level of management practical for each pond regardless of size or accessibility.
