Neighbors in East Windsor said Broad Brook Mill Pond's water levels are dropping, causing the area to smell.
With the water level lower than usual, there are islands forming and weeds and grass are growing, which is something that was not there before and residents want something done about it.
"It needs to be cleaned out," said Judy Gingras, of East Windsor.
Gingras moved across the street from the pond because of the scenery, but she said it is not what it used to be.
"What happens is a film goes over it and that smell is so bad you don't come out and sit, it's got a fishy smell," Gingras added.
Water levels have dropped about two feet over the last few years, and just last fall people were rescuing fish that were trapped in the low areas of water.
The water is low because of broken boards that are designed to relieve water pressure when there is a flood.
The design was popular in the 1980s, and now the dam needs an upgrade.
"We have an issue and we need to fix it," said Len Norton, East Windsor's director of Public Works.
The town has applied for a $500,000 grant for a long-term fix, however, town officials are not sure when they will hear if they're approved for the grant.
As a temporary fix, public works crews want to lower the water so they can replace the boards that are broken.
