Resort from 1929-1961, park since 1971.
Where the bikepath enters the park, a small stream runs from
a culvert under Flynn Avenue, across a small, low-lying wedge
of woods, and into another culvert before flowing into the lake.

Flynn Avenue and the environs of Oakledge Park

Aerial photographs from 1937 show a small, unnamed stream
running from the railroad tracks to the lake on the north end of
the property.

Question: a stream
is clearly visible in
the 1937 aerial
photograph, but
has largely
vanished by 1999.
What happened to
the stream in the
interim time?

Current stream:
GPS Coordinates: 4924080 N 0641245
Runs ~80 m through woods.
Average width of 2 m, average depth of 20
cm.
Channel constrained mostly by vegetation.
Evidence of other channels across the
floodplain (exposed roots, standing water).
Poorly defined banks. Champlain Sea
sediment.
Discharge: .019 m3/s

Lake shoreline has retreated.
1988 ponds mostly coincident with 1962 pond and current ponds.
Culvert under bikepath constructed post-1962.

The stream has been contained into
ponds and culverts as the area has
been developed. Little of the original
stream remains.
