Island Lake is one of three high mountain lakes in the Brown Duck Basin dammed by the Farnsworth Canal and Reservoir Company in The dam itself is representative and relatively well-preserved, but the replacement of the outlet mechanism has compromised its historical integrity.

Historical Information
The Farnsworth Canal and Reservoir Company filed for irrigation watr storage rights on three high mountain lakes-Island, Kidney and Brown Duck in the Lake Fork River drainage in July The permits were approved by the State Engineer the following April and, by November small-scale earth-fill dams had been completed at all three lakes to raise and control the water levels. Damming Island Lake changed its character significantly. Originally two smaller natural lakes located on a tributary of the Lake Fork River, these were joined into a single reservoir with an island near the center by the higher water. The dam featured typical earth-fill construction, with sloped, riprap-covered faces and an inclined steel gate over a 40-inch corrugated steel outlet pipe.
The outlet works were replaced in with the current inclined steel outlet pipe and screw. It is proposed that the dam be breached to lower the lake to within two feet of its naturAl level.
