Management Objectives:
  • Water Quantity - Improve the volume, distribution and timing of freshwater flows into Biscayne Bay.
  • Water Quality - Develop and achieve water quality targets to protect and restore natural ecosystems and compatible human-uses.
  • Environmental Protection - Protect and restore critical plant communities (mangroves, wetlands, seagrasses, etc.) that provide habitat, attenuate stormwater runoff, and improve water quality.

Springs

  •  Historical Documentation: Springs along the bay shoreline and on the rock outcrops along it are documented in many pioneer reports. These are consistent with known aspects of karst limestones such as the Miami Oolite.
  • Aerial Photography: Historical aerial photography shows evidence of springs
  • Seepage: Seepage into the bay both directly and through the sediment cover.

Creeks

Transverse glades
  • Typically 1-2 km wide.
  • Typically 2-3 m deep.
  • Increased gradient compared to Everglades.
  • Provide “path of least resistance” to water flows.
  • Now channelized by canals.

Performance Measures Related to Historic Flow
  • Percentage of total freshwater flow through coastal canals is reduced by redirecting through coastal wetlands.
  • The number of freshwater creeks or outlets to the Bay through coastal wetlands are re-created.
  • Salinity patterns that favor oyster habitat development.
  • Nearshore salinity patterns indicate a broader area of extended duration mesohaline conditions.
  • Reduce areal extent and frequency of hypersaline conditions.
  • Salinity becomes more characteristic of an estuary in some creeks.
  • The runoff hydrograph measured at the shoreline becomes significantly flatter, and exhibits increased duration of discharge from affected basins.
