Ennis Lake was formed by the erection of the Ennis Dam on the Madison
River. The lake is quite shallow and can get very warm during the
height of summer - resulting in some fish kill and limiting populations.
Despite that, Ennis Lake has some large rainbow and brown trout that
can be found in the lakes deeper holes. Unfortunately, locating these
holes on the moderate sized lake can be a challenge without a depth finder
or someone knowledgeable about the lake. Large streamers on sinking lines
are the best choice for catching these larger trout.
Access to the lake is adequate, with a decent fishing access site and
boat ramp available on the western side of the lake near the town of
Ennis. While Ennis Lake is not huge, it is still fairly sizable and can
be quite windy, making float tubing a difficult proposition. Anglers
will find the best success either using a motorboat or a canoe or inflatable
