View from highway ( Looking at the Tamiami Canal ) Driving west. The Tamiami Canal is located in Miami-Dade County. It drains eastward from Water Conservation Area III past Miami International Airport to a non-navigable salinity control structure that prevents saltwater intrusion from the Atlantic Ocean. Tamiami Canal provides excellent freshwater fishing in more than 27 miles of boat accessible canals and small lakes. The canal ranges from 40 to over 100 feet in width, averages about eight feet deep, and some lakes are more than 50 feet deep.
