Fish Stocked by Species for the Last Ten Years
|1 - indicates fish purchased and stocked by private citizens and sporting groups.|
|2 - indicates fish purchased by the DNR for stocking.|
|Stocking Fish Sizes|
|Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.|
|Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.|
|Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.|
|Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.|
Orono Lake is a 281-acre reservoir in southeast Sherburne County. It formed by a dam on the Elk River at the City of Elk River. The lake was drawn down in 1999 to allow dredging of accumulated sediment in selected areas. Adult black crappie and bluegill were stocked between 1999-2003 to re-establish the populations. Daytime electrofishing was conducted in spring 2000 and 2003 to survey the fish populations; and trap nets were used in spring 2001-2003 to further evaluate the recovery of the fishery. This was the first full survey since 1984.
The most abundant species in gill nets were black bullhead, shorthead redhorse, white sucker, yellow bullhead and yellow perch. All of these were within the range of expected values for lakes similar to Orono, except for shorthead redhorse, which were above the normal range. All of these species are common in the Elk River and naturally exist in Orono Lake.
Important sport species such as walleye and northern pike were less abundant but still within the range of expected values and anglers can expect to catch an occasional walleye and northern pike. Twenty percent of northern pike were greater than 24 inches in length.
Electrofishing in 2008 found many smallmouth bass, which ranged in size from five to 19 inches. Largemouth are also present but smallmouth are more prevalent as is the case for the Elk River also.
Overall, catches were light in trap nets. Previous trap net assessments sampled few fish and it is unclear why net catches are low. The most abundant species in trap nets were black crappie and silver redhorse. When bluegill were caught in low numbers in 2003, electrofishing showed that bluegill were captured at a rate of 61.9/hour. Progeny from these fish should provide populations into the future.
Black crappie were present in modest numbers and ranged from 5 to 13 inches in size. Anglers can expect to catch an occasional large crappie.
The survey marked the first occurrence of channel catfish. Two small fish less than eight inches were taken in trap nets. Previously, catfish were found below the Orono Lake Dam.
It appeared that most species have recovered from the draw down in 1999. Further stocking does not appear to be necessary.
