Red Mills Quadrangle

This is, to say the least, a very interesting, but not completely unique situation.  This location is listed on the USGS GNIS data base as a historical stretch of rapids.

Typically, historical waterfalls and rapids occur because a hydro-dam was built in the area.  Many times, the flooding that resulted covered the waterfall or rapids that was there.  In this case, there was no dam built.  The coordinates point to a spot about 500' off the mainland, about half-way across the channel to Galop Island.  Depth markers there show it to be about 30'.  The water level here was altered when the St. Lawrence Seaway Project was built back in the 1950s.  Eisenhower Lock, which is the most upstream lock in the system, is about 30 miles downstream from here.  The elevation above sea level change above and below Eisenhower is 46'.  

Earlier we mentioned that this situation was not completely unique.  South Sault Rapids, downstream of here, is a similar situation in the St. Lawrence River.

This location is on the St. Lawrence River.
