Welcome to the new version of Miami-Dade County's website. We'd love your feedback. While we're at work, you may be directed to, which is still your primary source for information.


Thank you, sponsors, partners, volunteers and participants for making Baynanza 2018 a success. This year it was exciting that Baynanza participants were able to assist with Vizcaya's Biscayne Bay Drift Card Study. Please continue to do the shore thing and keep Biscayne Bay clean all year long.

Baynanza is a celebration of Biscayne Bay and its significance as one of our most important ecological systems in South Florida. While Baynanza includes more than 25 great events throughout March and April, the event that has become nearly synonymous with this celebration is the Biscayne Bay Cleanup Day.


The early 1980s marked the beginning of a monumental effort by Miami-Dade County to save Biscayne Bay. The Bay was suffering from pollution and the marine environment of the Bay was in steep decline. Baynanza was created as part of a larger effort to save the bay.


College and university students are invited to enter to win prizes and recognition. Read Baynanza 2019 Photography Contest details.

    • Mosquito Repellent
    • Hat or visor
    • Sunglasses
  • Biscayne Bay Drift Card Study

    In 2016, Vizcaya approached the Patricia and Phillip Frost Museum of Science and CARTHE, a team of ocean scientists at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science to start a conversation about trash and pollution at Vizcaya. Together they launched an experiment, The Biscayne Bay Drift Card Study (#BayDrift), to identify the origin of the trash washing up into the basin of the Barge and mangroves around Vizcaya as well as the rest of Biscayne Bay.

    How #BayDrift works:
    Throughout the year, the Bay Drift team conducted 4 experiments, in different seasons and during different tides. At each experiment small wooden drift cards (inscribed with instructions on how to report them when found) were released by school students and members of the community. Additionally, CARTHE released GPS-equipped biodegradable drifters, designed to capture accurate tracks as they move through the bay.

    What we have learned:
    Data tracks reveal how currents and tides move debris around Biscayne Bay. Though scientists are still analyzing the data, it is clear that trash released in the bay, remains in the bay. Debris released into the northern bay is likely to stay there. More data is needed to understand the patterns in the southern bay.

    How to get involved:
    As of January 2018, 17 schools and 15 community-based organizations have supported #BayDrift. You can help by disposing of trash properly and volunteering to clean up the coastline. Recycle and reuse whenever possible. Participate in #BayDrift by going on walks after releases to look for cards, and spread the word about the study! Follow #BayDrift on social media platforms for more information about upcoming #BayDrift activities.
