Lake Isom
Encyclopedia
Lake Isom is a small natural lake
located in Lake County, Tennessee immediately south of Reelfoot Lake
. It is fed by Running Reelfoot Bayou
, the outlet stream of Reelfoot Lake. Like Reelfoot, it was formed in the New Madrid Earthquake
s of 1811-1812 and it is very shallow and swamp
y. The entire lake and its environs, covering 1,846 acres (747 ha) comprise the Lake Isom National Wildlife Refuge and have been such since 1938.
Lake Isom has suffered from considerable silt
ation in the past, making it even shallower and swampier than it already was. Improved agricultural
practices in the area are slowing this development, however.
Due to the long-term federal ownership and its smaller size, Lake Isom is almost entirely undeveloped and is not surrounded with parks, restaurants, and hunting and fishing camps as is Reelfoot. Motors on boats on the lake are also limited to 10 horsepower.
