The address is :
Paper Mill Rd
Phoenix, MD 21131

Coming from York Road cross over the Paper mill road Bridge. On your left you will be able to already see the 'lake'. 100 yards down on the left there is small break on the side of the road to park (carefully). You can walk to the flats below or walk back up to the bridge and view from there.

If anyone is there, please notify me if the black-swan is still there!!

Thank you,
Mordechai
