Rain water wasn't the only thing flowing into the Jones Falls this week.
The Baltimore City Department of Public Works believes 48,000 gallons of sewer water overflowed into the stream following rain on Thursday.
The incident happened at underground at a structure overflow at North Charles and West Lanvale Streets. That structured overflow runs into a storm drain that flows to the Jones Falls.
DPW says structured overflows were designed into Baltimore's sewer system more than a century ago. They act as release valves when pipes are flooded by rainwater that enters the system during significant storms.
As part of a $2 billion consent decree, those structured overflows are being eliminated.
