Alternative Text Description for Surface Water Classification

TABLE OF CONTENTS

MAP OVERVIEW

This map displays the Surface Water Classification system for Florida, showing Class I and Class II water bodies as defined under the Clean Water Act. The map illustrates where different levels of water quality protection are designated based on the intended use of surface waters. Class I waters are designated for potable water supplies, while Class II waters are designated for shellfish propagation or harvesting, with these classifications arranged according to the degree of environmental protection required.

GEOGRAPHIC CONTEXT

The map covers the state of Florida and portions of neighboring states including southern Georgia and Alabama. Major cities labeled include Jacksonville on the northeast coast, Orlando in central Florida, Tampa and St. Petersburg on the west coast, Cape Coral in southwest Florida, and Miami in the southeast. The map shows both coastal areas along the Atlantic Ocean to the east and the Gulf of America to the west and south. Additional labeled cities include Tallahassee in the Florida Panhandle, Gainesville in north-central Florida, and smaller communities such as Dothan and Albany in Georgia, Valdosta in Georgia, Palm Coast on the east coast, Lakeland in central Florida, Melbourne and Palm Bay on the east coast, Port St. Lucie on the southeast coast, West Palm Beach, and Coral Springs in southeast Florida.

KEY INSIGHTS

The map reveals that Class II waters (shellfish harvesting areas) are concentrated along Florida's coastal zones, forming a nearly continuous band around the peninsula. These coastal waters extend from the Florida Panhandle along the Gulf of America coast southward to the Florida Keys, and northward along the Atlantic coast. Class I waters (potable water supply areas) appear in isolated locations, with one notable area visible in the southeast near Port St. Lucie. The distribution pattern shows that water quality classifications in Florida are strongly tied to geography and intended use, with shellfish harvesting zones confined to coastal marine environments and drinking water supply areas appearing as discrete inland or nearshore locations.

VISUAL ELEMENTS

Surface Water Classification

This layer represents the designated use classifications for Florida's surface waters as required by the Clean Water Act.

Class 1 (Light blue fill)

Appearance:

Light blue colored polygons

Distribution:

Class 1 waters appear as isolated features rather than continuous zones. One clearly visible Class 1 area is located in southeast Florida near Port St. Lucie.

Notable locations:

Southeast coastal Florida near Port St. Lucie and West Palm Beach area

Spatial patterns:

Class 1 features are discrete and separated, representing specific waterbodies designated as potable water supplies. They do not form connected networks and appear as individual impoundments or water supply areas.

Class 2 (Light green fill)

Appearance:

Light green colored polygons

Distribution:

Class 2 waters form extensive coastal zones around the Florida peninsula. They appear along the entire Gulf of America coastline from the Panhandle through southwest Florida to the Keys, and along the Atlantic coastline from Miami northward past Jacksonville.

Notable locations:

Continuous distribution along the Panhandle coast near Tallahassee and the Big Bend region, Tampa Bay area, southwest Florida coast near Cape Coral, Florida Keys and southern tip of the peninsula, southeast Atlantic coast near Miami, central Atlantic coast near Melbourne and Palm Bay, and northeast coast near Jacksonville.

Spatial patterns:

Class 2 waters follow the coastline closely, forming a ribbon-like pattern that traces Florida's marine and estuarine environments. The distribution is nearly continuous with only small gaps, indicating extensive shellfish harvesting areas throughout Florida's coastal waters.

Class 3 (Light pink fill)

Appearance:

Light pink colored polygon

Distribution:

Only one small Class 3 area is visible in the legend, but no clearly identifiable Class 3 features are apparent in the main map area at this scale.

Notable locations:

Not clearly visible on this map

Spatial patterns:

Class 3 waters are not prominently displayed at this map scale or may be too small to distinguish from other features.

Overlapping Patterns

No significant overlapping patterns are visible between the classification types. The classes appear as distinct, non-overlapping polygons representing different designated use areas.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map represents a regulatory classification system rather than current water quality conditions. The classifications indicate designated uses that determine the level of protection required under Florida's water quality standards. Florida has six total water classification classes arranged in order of degree of protection required, though only Classes 1, 2, and 3 appear in the legend. For complete descriptions of all classes and specific waterbody designations, users should reference Florida Administrative Code 62-302.400. The map displays only Class I and Class II boundaries as indicated in the layer description.

DATA CONTEXT

Data Source:

Surface water classification data is based on Florida's implementation of the Clean Water Act requirements for designated use classifications. The data represents regulatory boundaries established under Florida's water quality standards program.

Data source layer name: SWC_APR24

Definition Query:

No definition query or filter criteria was specified. The map displays Class I and Class II surface water classification boundaries.

Scale Information:

The map is displayed at a statewide scale showing all of Florida and portions of neighboring states. At this scale, small individual water bodies may not be visible, and the map is appropriate for understanding regional patterns of water classification rather than site-specific details.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The data source layer name indicates this is April 2024 data (SWC_APR24).

Limitations:

At this statewide scale, small Class I water bodies may be difficult to see or may not be visible. The map shows only Class I and Class II classifications, though Florida's system includes six total classes. Class boundaries represent designated uses for regulatory purposes and do not indicate current water quality conditions. For detailed information about specific waterbodies and their classifications, consultation of Florida Administrative Code 62-302.400 is recommended.

Map Coverage:

The map extent covers the entire state of Florida from the Alabama-Georgia border in the north to the Florida Keys in the south, and from the Gulf of America coast in the west to the Atlantic Ocean coast in the east. Portions of southern Georgia, southern Alabama, and adjacent coastal waters are visible for geographic context.
