A recomputation of the drainage area above Mountain View, made by the
northern New Jersey flood commission, shows that it is 380 square miles
in extent. It was decided by this commission that the construction of
this reservoir would be the most approved method of preventing
disastrous floods in the lower valley of the Passaic. By raising a dam
to a height of 202 feet above tide, 8 inches of water on the drainage
area above might be held back, which, it was believed, would be a
sufficient maximum for flood catchment. With this amount of storage the
estimates of the flood commission showed that the remainder of the
drainage area would not turn a sufficient amount of water into the lower
valley channel to cause flood damages.
