MEMPHIS, Tenn. (AP) — Officials in Tennessee say public works crews have fixed a second sewage leak discovered in the area where a larger pipe broke and sent millions of gallons of untreated wastewater into a creek and lake.

In a statement, the city of Memphis said Friday that a plug has been placed in a 60-inch pipe that broke and sent an estimated 1,000 gallons per day into Cypress Creek and adjoining McKellar Lake in Memphis.

Officials said the leak was discovered after a bypass was installed in a 96-inch pipe that collapsed March 31, sending 50 million gallons of sewage per day into the creek and lake. That larger leak caused a major fish kill and led to high levels of E.coli in both bodies of water. It was fixed overnight Thursday.
