8 fish cooperatively purchased, raised, and/or stocked by U.S. Fish and Wildlife Service.

Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

The Courthouse Lake fish population has changed significantly in recent years due to flooding. The 1993 flood allowed many species found in the Minnesota River to migrate into the lake, including northern pike. Since Courthouse is a designated trout lake, northern pike are not a desirable species to have present. Therefore a total lake reclaimation was deemed nessessary. This was scheduled for the fall of 1994. During the spring of 1995 rainbow trout will be restocked in the lake.
