Mattoon Lake

Mattoon Lake is located near Ellensburg.  It has a year-round season with excellent angling opportunities for 8- to 14-inch rainbow trout from early spring to summer.  The lake is also stocked with jumbo rainbow trout (1-1.5 lbs each) in the spring.

Later in the fall, Mattoon is stocked with some large 6-12 lb rainbow trout broodstock.  The lake has good bank fishing opportunity for those who do not have boats, although the lake can get quite weedy in the summer. 

There is a boat launch, but internal combustion engines are prohibited.  This is a great place to take the family for a fun fishing outing.  No camping. 

Two-pole fishing is allowed
