MAP OVERVIEW

This map displays adopted river minimum flows and levels (MFLs) across Florida as of March 2021. The map shows river segments where water management districts have established regulatory MFL thresholds to protect water resources. These features are represented as blue linear segments distributed across the state, indicating rivers and stream reaches with formally adopted minimum flow and level standards.

GEOGRAPHIC CONTEXT

The map covers the entire state of Florida, from Jacksonville in the northeast to the Keys in the south, and from the Atlantic coast to the Gulf of America coast. Major cities labeled on the map include Jacksonville, Gainesville, Ocala, Daytona Beach, Orlando, Tampa, St. Petersburg, Clearwater, Sarasota, Port Charlotte, Cape Coral, Melbourne, Palm Bay, Titusville, and Port St. Lucie. The map extends from the Georgia border in the north to the southern tip of the Florida peninsula. Lake Okeechobee is visible in the south-central portion of the state.

KEY INSIGHTS

Adopted river MFLs are concentrated in north-central and west-central Florida, with a notable cluster of river segments around the Tampa Bay region and throughout the northern interior of the state. The eastern coastal areas and southern Florida show fewer adopted river MFLs. A prominent concentration appears along rivers in the northwest and north-central regions, suggesting greater regulatory focus on water management in these areas. The distribution reveals that not all river systems across Florida have adopted MFLs, with gaps visible in portions of central and southern Florida.

VISUAL ELEMENTS

Adopted River MFLs

This layer represents river segments with formally adopted minimum flows and levels established by Florida's water management districts.

Adopted River MFL Segments (blue lines)

Appearance:

Blue linear features of varying lengths representing river and stream reaches with adopted MFL standards.

Distribution:

River segments are distributed throughout Florida, with highest concentrations in the northern and west-central portions of the state, particularly around the Tampa Bay area and north-central interior regions.

Notable locations:

• Dense network of MFL-designated rivers in north-central Florida between Gainesville and Ocala
• Multiple river segments radiating from the Tampa Bay metropolitan area
• Several designated rivers in northwest Florida near the panhandle
• River segments near Jacksonville in northeast Florida
• Scattered designations along Florida's east coast from Jacksonville south to Palm Bay
• Limited representation in south Florida and the Lake Okeechobee region

Spatial patterns:

River segments follow natural drainage patterns and watershed boundaries. There is a clear concentration in the central portion of the state with diminishing density toward coastal areas and the southern peninsula. The pattern suggests prioritization of inland freshwater river systems for MFL adoption, with rivers often extending from interior areas toward coastal regions.

Overlapping Patterns

In areas with higher river density, particularly in north-central Florida, multiple river segments with adopted MFLs occur in close proximity, reflecting comprehensive watershed management across interconnected river systems.

SYMBOL GUIDE

• Blue lines: River segments with adopted minimum flows and levels as established by Florida water management districts

ADDITIONAL INFORMATION

This map represents regulatory designations rather than all rivers in Florida. The presence of an adopted river MFL indicates that the water management district has established specific minimum flow and level thresholds for that segment to prevent significant harm to water resources and associated ecosystems. Rivers without visible blue lines have not yet received adopted MFL designations as of the March 2021 dataset. The map reflects the work of five water management districts: Northwest Florida Water Management District (NWFWMD), Suwannee River Water Management District (SRWMD), St. Johns River Water Management District (SJRWMD), Southwest Florida Water Management District (SWFWMD), and South Florida Water Management District (SFWMD).

DATA CONTEXT

Data Source:

The data was compiled by the Florida Department of Environmental Protection's Office of Water Policy from information provided by each of Florida's water management districts. The dataset represents features that identify adopted river minimum flows and levels across districts with adopted river MFLs as of March 2021.

Data source layer name: MFL_RIVER_MAR25

Definition Query:

No definition query or filter criteria was applied to this dataset.

Scale Information:

The map displays statewide coverage at a scale appropriate for viewing all adopted river MFLs across Florida. Individual river segment details are visible at this zoom level.

Coordinate System:

NAD_1983_HARN_Florida_GDL_Albers (WKID 3087)

Time Period of Content:

The data represents adopted river MFLs as of March 2021.

Limitations:

This map only shows rivers with adopted MFLs and does not represent all river systems in Florida. Additional rivers may have MFL designations adopted after March 2021. For technical issues or data updates, users should contact pamela.flores@floridadep.gov. The attributes for each MFL contain additional technical information not visible in this map view.

Map Coverage:

The map covers the entire state of Florida from the Georgia border south to the Florida Keys and from the Atlantic Ocean west to the Gulf of America coast.
