Right now, the Water Conservation Areas (WCAs), which are massive wetlands that help move water through the central Everglades, under Tamiami trail, and into Everglades National Park, are higher than they should be—about a foot higher.
Unfortunately, the Tamiami Trail highway bisects the Everglades east to west, creating a barrier and bottleneck for the flow of water south. This can sometimes cause a harmful high-water situation in the WCAs, like we’re seeing right now.
Solutions are on the horizon
In recent years, under the Comprehensive Everglades Restoration Plan (CERP), there have been some major improvements to facilitate more flow under Tamiami Trail and prevent water from stacking up in the WCAs.
Ongoing seepage and flood-control projects in the 8.5 Square Mile Area, removal of the Old Tamiami Trail roadbed, and bridges raised on the Tamiami Trail have given water managers far more capacity to flow water from the WCAs under the Tamiami Trail and into Everglades National Park.
