Ohio Gov Declares Emergency Over Toxic Lake Erie Blooms

COLUMBUS, Ohio — Gov. Mike DeWine declared a state of emergency Friday amid escalating harmful algal blooms (HABs) in Lake Erie's western basin, prompting water use restrictions in northwest Ohio communities including Toledo and surrounding Lucas County.[6] The blooms, fueled by phosphorus and nitrogen runoff from farms and urban areas, have produced toxins like microcystin exceeding safe levels in raw lake water intakes.[1][2] Ohio EPA reported elevated cyanotoxin concentrations at multiple sites, triggering red advisories that bar swimming and water contact along state park beaches from Maumee Bay to East Harbor.[4] The crisis recalls Toledo's infamous 2014 "do not drink" order, when microcystin contaminated the city's supply, affecting 500,000 residents for three days and costing millions in bottled water and treatment.[1][2] Lake Erie, the Great Lakes' shallowest and warmest, sees peak HABs from July to October, with NOAA forecasting above-average severity this season due to warmer waters and heavy spring rains boosting nutrient loads.[8] State Rep. Chris Redfern, D-Catawba Island, called for emergency funding to deploy barriers and enhance monitoring in Ottawa and Erie counties.[3] Ohio's Harmful Algal Bloom Research Initiative (HABRI), backed by 29 science teams, aids agencies like Ohio EPA and Department of Health in optimizing toxin removal at treatment plants and tracking nutrient pathways from Maumee River watersheds.[5] The Ohio Lake Erie Commission coordinates with USGS and local health districts for real-time BeachGuard advisories, while residents are urged to avoid scummy water, report blooms via ohioalgaeinfo.com, and rinse pets after exposure.[4][7] Federal partners, including Rep. Marcy Kaptur's office, provide weekly bulletins as blooms encroach on drinking water for 11 million in the basin.[1]
