Upper Lake Is Emptied.
The Hatfield water power consists of
two great lakes or reservoirs, each
covering several miles. The first, or
upper reservoir, has been retained by
the Dells Dam, a concrete structure
embedded in solid rock on one side
and with core wall running to the
west. 1t was this wall which gave
way, emptying the great lake into the
lower reservoir.
The lower and larger dam at Hat
field is built in the same way and the
water, rising swiftly, washed out the
several feet of earth covering the west
core wall here, and tore down the
canal and surrounding country. Eleven
feet of water poured over the
crest of the main dam. These breaks
brought about the present flood, but
the main body of water is still re
tanned in the lower lake by the big
dam at Hatfield.
The present flood is the worst In
the history of Black River. Torren
tial rains above the reservoir sent the
water UP. repeatedly and the efforts OF
300 laborers. who worked to prevent
the disaster, were Of no avail. The
workmen have been called off, as moth
ing more can be done, and practically
all depends upon the strength Of the
big dam, and the elements.
The flood reached Melrose carrying
away roads and bridges, but the people
had been forewarned and escaped to
safety.
