1934 USGS Nautical Chart
Aerial Photography was not yet used widely and this map seems to be based on interviews with the land holders. This makes it accurate in some ways and inaccurate in others.
This circle represent the fact that Monquin and Pampatike Creek come from the same creek.  It was odd to see at first, but makes sense if the information came from an interview.
The fact that Dam Creek and Pamptaike connect, which used to be the same creek, again verifies the information that this chart is built from is oral. When the dike was built, The new mouth to Pampatike was built, so they have never been physically connected.
This branch of Pampatike has a dam on it at this time, so it is understandable as to why it is confused with the real Dam Creek.
Dam Creek
Pampatike Creek
Moncuin Creek
