Story

Fifteen years of collapse and comeback.

The long story of the Indian River Lagoon — from the 2011 super-bloom that started the collapse, through the 2016 fish kill that made national news, through the tax that same year that funded the fight back, through the 2021 manatee die-off, and into the recovery now underway.

Read the full timeline.

The most complete, sourced chronology of the lagoon’s collapse and recovery lives on the timeline page — 15+ dated events from the 2011 super-bloom to the November 3, 2026 ballot, with major factual claims linked to primary or authoritative source material.

Over the summer and fall of 2026, the Story section is expanding with:

  • Before the fish kill — how the lagoon got so vulnerable in the first place. Citrus, coastal development, the seawall era, and the slow accumulation of muck and septic.
  • The 2011 super-bloom — a lagoon-wide algal bloom that, combined with subsequent stress events, drove roughly a 43% loss of mapped seagrass between 2009 and 2011 mapping windows and set up the 2016 collapse.
  • 2016: the year everything broke, and the year we did something about it — the fish kill and the tax vote, in the same eight months.
  • The manatee mortality event (2020–2022) — The U.S. Fish and Wildlife Service administratively closed the Atlantic-coast Florida manatee Unusual Mortality Event on March 14, 2025. The retrospectively defined event period ran December 1, 2020 through April 30, 2022; its 1,392 cases comprise 1,255 carcasses and 137 rescues, not 1,392 deaths. FWC reports that Atlantic-coast mortality returned to expected levels; habitat concerns and monitoring continue. The event period and the closure date are different, and closure does not establish full habitat or forage recovery. What the record said, why it happened, and what changed after.
  • The comeback (2023–2026) — mapped seagrass extent and selected water-quality indicators have improved in parts of the lagoon, while official assessments continue to describe recovery as incomplete and vulnerable to weather, runoff, algal blooms and other stressors.
