MIAMI (CBSMiami) — A no swim advisory is in effect for the Oleta River Park area and it’s all because of that relentless rain the past few days.

According to Miami-Dade County, the excessive rain caused “a significant increase of water entering into the North District Wastewater Treatment Plant on Monday, May 25 along with the disposal of wipes and other non-flushable items that resulted in a wastewater overflow at the plant.”
