Monroe County Mayor Holly Merrill Raschein recently visited Canal 90 between Hilson and Ivanhoe courts in Key Largo to view the canal restoration efforts.
Restoration work includes backfilling the canal. This raises the canal bottom to an optimum depth of about 7 feet to allow maximum flushing and tidal flow in and out of the canal. This technique will increase the levels of dissolved oxygen throughout the canal. The work is funded by a Florida Department of Environmental Protection Keys Stewardship grant to the county.
“These improvements restore the canal’s impaired waters and bring the dissolved oxygen levels up to meet State water quality standards, which will greatly enhance the levels of marine life in the canals,” said Rhonda Haag, county chief resilience officer. “Residents should see an immediate increase in marine life once the project is completed.”
The crew also continuously monitors the canal for manatees seen in the area. Activity stops if manatees enter the area while restoration work is underway.Additional restoration projects for other poor and fair water quality canals in the Florida Keys will move forward as grant funding allows. Canal restoration improves the overall health of canals and nearshore waters.
