Sewage overflowed into Scajaquada Creek, Cazenovia Creek, Eighteen Mile Creek and other creeks Tuesday and today from wastewater treatment plants overwhelmed from melting snow.
NY-Alert, the state's emergency alert system, reported overflows in Lancaster, Cheektowaga, Derby, Blasdell, West Seneca and the Town of Tonawanda.
Typically, sewage overflows get more attention after summer rainstorms because health officials close beaches.
But, wastewater treatment plants are also inundated at other times of the year, including during the winter and spring after snow piles melt and the water finds its way into sewage systems.
For instance, at one overflow Tuesday in Hamburg, an estimated 630,000 gallons of untreated sewage was released into a drainage ditch near Rogers Road, according to an alert.
