A scenic pond in Mount Pearl has been noticeably changed after nearby development caused silt to brown the waters.

Resident Randy Shaw said he's been walking the trail near Power's Pond for the last 23 years, but on Friday of last week he noticed a big change in the water.

Construction on the nearby Glencrest development, a project by former premier Danny Williams, has forced silt into the water, and Shaw said developers need to be more accountable.

"When you come around and you see that it's brown when you used to see the rocks and the bottom, there's something wrong with that. There's something definitely wrong with that," Shaw said.

"I'm not against progress, but I think when they see what's happening, they shouldn't do this to this area."

Shaw contacted city hall about the situation, and found out he isn't the first to make a complaint.

Not long after, silt dams appeared at the bottom of the Glencrest development, as well as in the stream that drains Glencrest Heights and drains into the marshland surrounding Power's Pond.

According to Shaw, it took the city and the developers too long to respond.

"They don't react on it fast enough to find out what the problem is, that's my biggest concern," he said.

"Besides the fact that if there's any living, I would assume any fish that are in there has to be dead by now because of all the silt going in."

The company doing the excavating said it complied with all environmental protection requirements, but confirmed it got a stop work order from Mount Pearl earlier this week and was told to beef up its protective measures.
