Florida Lake Regions:

A Classification System
Where Does Your Lake Fit In?
The Lake Region Classification System
can be a useful tool for managing your lake.
By reading this handout, you can learn:

> How and why the Florida Lake Regions
project was developed;
> How to compare your lake with other lakes
in its Lake Region; and
> How the Lake Region Classification System ./
can be useful to you.

W ith more than 7800 lakes in the state and a limited number of lake management professionals
available, the task of creating a lake management plan for every lake is simply not feasible.
The Florida Lake Region classification system was initiated to provide a framework of the
different types of lakes in the state so that management plans can be developed for groups of
lakes with similar characteristics.
This classification system was created by grouping lakes based on similarities in physiography,*
geology,* soils, hydrology,* water chemistry, vegetation, and climate. It was a cooperative effort
involving the United States Environmental Protection Agency (U.S. EPA), the Florida Department of
Environmental Protection, and researchers at the University of Florida's Department of Fisheries and
Aquatic Sciences.
Data used for the project were collected from hundreds of lakes in Florida, by scientists, students, and
citizen volunteers. The three-year project resulted in the definition of 47 regions, which are described in a
final report Lake Regions ofFlorida (Griffith, G.E., et al. 1997), published by the U.S. EPA (EPA/R-
By documenting regional differences within the 47 Florida Lake Regions, reasonable and realistic goals
can be developed for lakes individually or in groups. This approach also improves the ability to predict the
effects of lake management practices.
The Lake Regions Classification System can also
be used to assess how your lake compares with
others in its region.
To compare your LAKEWATCH lake with others in its
region you'll need to know the long-term average for each of the
four water chemistry parameters that have been monitored for
LAKEWATCH. You can obtain this information from the
Florida LAKEWATCH office by requesting a Lake Region
summary (be sure to include the name of the lake and the county
it's located in).

*Physiography is a science that deals with the physical aspects of
the earth and its life (e.g., land, sea, air, and distribution of plant
and animal life). Geology is a science that deals with the history of
the earth and its life, especially as recorded in rocks. Hydrology is
a science dealing with the properties, distribution and circulation
of water on the surface of the land.

59 pg/L as an effective way to achieve this goal. The information
that waterbodies in this Lake Region are "naturally rich in
phosphorus" and that 59 uig/L is already at the bottom of the observed phosphorus range, suggests that
further reducing the phosphorus level in this lake would probably be very expensive and labor intensive.
Other options such as appropriate aquatic plant management strategies might have a better chance of
success and should be explored.
To learn how to set goals for your lake, ask LAKEWATCH to send you the free booklet, "How To Create a
Lake Management Plan" developed by Jess VanDyke of The Florida Department of Environmental
Protection in cooperation with Florida LAKEWATCH.

> Monitor over the long term to see if your lake remains consistent with others in
your Lake Region or if it becomes atypical.
For example, consider a lake located in the Lake Wales Ridge Transition Region that has average total
chlorophyll values higher than the average maximum values for other lakes in this region. The fact that
this lake is atypical suggests that something may have occurred which changed the original character of
the lake. It may be possible to reverse the effect, if its cause can be determined.
The Lake Region Classification System is just one way of grouping lakes.
