    Bayou Path Dr Stream in Atwater Subdivision by Lisa Hjorth

    The large pond that flows into the stream test site had ice on it. The outflow stream (test site) had no ice on it and 3 Mallard ducks were on the open water stream. Water was fairly clear and flowing. Three golf balls were visible, but not retrievable, on the stream bottom. The test site was part of a former golf course.
