Water Management in Taylor Slough and Effects on Florida Bay

Date Issued:
1993
Summary:
Current water management practices in the L-31N, L-31W, and C-111 canals have contributed to lower groundwater levels and reduced surface water flows in the Rocky Glades and the Taylor Slough marshes. The reduced hydraulic gradients and the truncated periods of flow through the Taylor Slough basin are thought to be a major factor contributing to the hypersaline conditions and abrupt salinity changes in Florida Bay. The progressive lowering of L-31N canal stages from 5.5 to 4.3 feet in response to pressure from expanding urban and agricultural development has increased drainage from the marshes in Everglades National Park into the bordering canal system. If one looks at the entire reach of L-31N from the S-335 to S-176, well over 270,000 acre-ft per year are drained from the western marshes into L-31N. Approximately 50,000 acre-ft are returned to Taylor Slough, while 180,000 acre-ft are dumped into the lower C-111 basin.
