Fishing maps/Biscayne Bay

Southeast Florida coastal fishing maps

Biscayne Bay fishing maps and surveyed sections

Six Biscayne Bay and Card Sound sections are live with quality-assured NOAA depth contours, transparent FWC and NPS fish evidence, confidence-tagged fishing spots, Southeast Florida forage guidance and verified public access.

Why Biscayne Bay is split into sections

One page would mix mainland mangrove shorelines, grass flats, navigation channels, mid-bay basins, outer hardbottom and Card Sound. The six pages preserve official FDEP assessment units, and each one independently clears the same shoreline, bathymetry and fishing-evidence checks.

Source-backed, not crowd-guessed

What is included on every live page

  • Depth: NOAA BlueTopo plus West Biscayne Bay bathymetric lidar and direct NOAA smooth-sheet soundings where needed; measured, assessed-interpolated and unsupported cells remain distinct.
  • Boundaries: official FDEP assessment units converted to water-only geometry with NOAA ENC land, then checked against NOAA CUSP and the tracked ENC land edge at the fixed 150 m/95% gate.
  • Fish: FWC common-catch guidance for northern Biscayne and the NPS reported-fish inventory for park waters, narrowed by inshore, mid-bay or outer-bay habitat and never represented as catch-rate data.
  • Spots: analysis anchored to NOAA charted wrecks and artificial reefs and FWC mapped seagrass and oyster habitat; recommendation-eligible spots require directly measured bathymetry.
  • Seasonality: Biscayne-specific bay anchovy and Florida mullet movement windows, presented as broad search ranges rather than daily predictions.
  • Access: open Florida FWC Boat Ramp Inventory records matched to the official outline or a verified named-water connection; closed Card Sound ramps remain excluded.

Every section passed independently

All six Biscayne Bay sections are live

The two outer sections initially missed the measured-coverage gate. Direct NOAA H09926, H10473, H10474 and H10493 soundings closed the documented gaps without lowering the standard. All six children now pass shoreline, depth, fish-evidence, fishing-spot, forage and access checks and are included in search and the sitemap.

Biscayne Bay map questions

Frequently asked questions

Why is Biscayne Bay divided into separate fishing-map pages?

Biscayne Bay spans inshore mangroves and grass flats, broad mid-bay basins, outer hardbottom and the connected Card Sound system. DepthScout follows six official Florida Department of Environmental Protection assessment units so shoreline, survey coverage, fishing structure and access remain useful at section scale.

Which Biscayne Bay fishing-map sections are available now?

North-Central Inshore, North-Central Outer, South-Central Inshore, South-Central Mid-Bay, South-Central Outer and Card Sound are live. Directly measured coverage ranges from 60.14% to 99.88%, assessed coverage ranges from 98.65% to 99.99%, and every section passes the fixed release gates.

What fish evidence is used for Biscayne Bay?

The statewide FWC FIM station layer has no records inside these six polygons, so DepthScout does not invent section-level counts. Northern rosters retain app-supported targets explicitly listed in FWC's Miami-Dade and Biscayne Bay common-catch guidance. Southern and Card Sound rosters use fish reported by the National Park Service from Biscayne National Park waters, narrowed by each section's habitat. Presence is not a catch-rate forecast.

What data supports Biscayne Bay depth and fishing spots?

Depth combines NOAA BlueTopo, 2018 NGS West Biscayne Bay topobathymetric lidar and direct NOAA H09926, H10473, H10474 and H10493 smooth-sheet soundings where needed. Fishing-spot candidates use NOAA charted wrecks and artificial reefs plus FWC mapped seagrass and oyster habitat; recommendation-eligible spots require directly measured bathymetry.

What seasonal forage is documented for Biscayne Bay?

The Southeast Florida calendar uses NOAA and NPS evidence for warm-season bay anchovy concentration and Florida-wide fall-to-winter mullet movement. These are broad search windows; tide, weather, salinity and visible bait determine the useful daily pattern.
