| What can cause this smell in a stream
On my morning walks there is a small stream that feeds a big pond/small lake, at the other end of the lake the stream emerges for about 10 feet then goes under the lane and feeds another small lake on the other side. Recently I have noticed that the stream between the 2 lakes has a white film on its bed, the stream at this point is flowing downhill over rocks and is only about 3" deep. There is also a sulphorous/bad egg smell. DOes anyone know the likely causes of this. Both lakes have a large amount of blanketweed covering them and I was wondering if the issue was caused by lack of oxygen killing of the lake plant llife and this rotting down and being washd along the stream. Going back to where the first lake is fed and about 50 yards from this stream is a very small industrial estate with a Aluminium fabricators and powder coating company, the stream by this company is slow moving and murky but there isn't any smell. Any tips would be welcome |
