The downtown consultants for the dredging of the waste lake at Montebello had underestimated the amount of material that could be possibly dredged from our waste lake – so they asked if it would be alright to remove the phragmites. A big OK to that.
Back in July I posted an aerial of the lake filled with sludge. This view shows most removed. The phrags were attached to the outfall structure and the contractor cut by hand. (At end of catwalk, lower center of lake). At lower right of lake more sludge accumulated due to a polymer added to belt presses, dumping back into this area.
Barge and excavator removing phragmites. The one shore is completed. Would be nice to have enough budgeted money to remove growth along shoreline.
Within one month the phragmites have grown a couple feet around outfall. Because the growth mat is attached to the structure, pulling away the growth will damage the wall. This outfall leads directly to Herring Run and we can not have this water going there.
What the waste lake by the outfall structure use to look like. Those houses are long gone.
Another view of the lake from years past. This is looking towards the NW corner where the surge pipe from Loch Raven is located. It was nice and clear of growth, inside and out. Those houses are also gone.
The waste lake shoreline was so clear that kids would come in and sail their model boats. This is looking towards the outfall structure.
