Weeki Wachee Natural System Carrying Capacity Study

Project Overview

An ecologically-based study is being done to evaluate how recreational use affects natural systems along the Weeki Wachee River in Hernando County, Florida. The study, known as a carrying capacity study, is intended to provide information to assist in making decisions that will better manage impacts of recreational use on this natural system.


The beauty of the river makes it a popular site for recreational activities. There are concerns about whether increased recreational use is affecting the ecology of the river. The study will not set a specific limit to recreation or address public safety but provide the science to governing agencies with authority to make future management decisions.

Project Partners

The project is being co-funded by Hernando County and the Southwest Florida Water Management District with in-kind support from the Florida Department of Environmental Protection.

Project Details

The year-long study is being conducted by a third-party consultant who will provide unbiased, scientific findings. To account for differences along the river, the Weeki Wachee Springs State Park, meandering middle reaches and tidally-influenced lower river will be evaluated separately.

To assess water quality, scientists will be collecting water samples. In-person tests will be done monthly May-September and bi-monthly October-April and during at least two holiday weekends in the summer. In addition, four data collection devices will be installed along the river to record water quality data continuously.

Recreational use will be captured by time-lapse cameras at sites along the river. In addition, recreational use by user type will be captured monthly May-September and bi-monthly October-April in one-hour increments for eight hours. Direct impacts to the natural system, such as prop scars and uprooting of vegetation or unnatural movement of sand, will be documented along with activities like docking, wading and trampling that may affect the river.

Additional data will be collected including:

  • Random surveys of people exiting the river asking questions such as time spent on the river, types of activities, number of stops, etc.
  • User counts from commercial recreational providers, which will be compared to the consultant’s observed user counts.
  • Damage from rope swing activity.
  • Types and quantities of wildlife present through time-lapse camera footage.

Based on the results of the study, there may be a range of potential management opportunities for decision makers to consider.

Project Timeline

The data-collection process began in May 2018 and will continue through August 2019. Once the study is completed, the results will be published for public view.
