We haven't operated the filter enough to see any noticeable difference from that project alone, unfortunately.  We have run about 3,000,000 gallons through the filter this fall during a few phases of operation as we learn more about how the system operates in real-time, what maintenance requirements it will have, and troubleshoot the occasional problem. The filter's operation is currently in a paused state and we will be forced to take it offline for the winter very soon as colder temperatures move in.

The dredging and restoration of the pond in Hansen Park alone accounts for most of the water quality improvements we expect from the project.  The iron-enhanced sand filter is a smaller, but also important, piece of the puzzle.  With all of the work done at Hansen Park, Mirror Lake, and Middle Rice Creek, in conjunction with future carp management efforts, we expect to see some measurable improvements in the quality and clarity in Long Lake over the coming years.

Stay tuned!
