Stocking Notes
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.

Fish Consumption Guidelines

These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Status of the Fishery (as of 08/09/2010)

Lake Irene is a 630-acre, mesotrophic (moderately fertile) bass-panfish lake located approximately one mile northwest of Miltona in Douglas County. Two public accesses are located on the northwest shore off of NW Irene Road and on the southeast shore off County Road 64.

Lake Irene's bass-bluegill fishery is in good shape. Largemouth bass abundance has increased nearly 200-percent since 2000 and 2005, with about 70-percent of the population currently measuring between 12 and 15-inches. Bluegill abundance has remained about the same since the 1980's but average individual size appears to be increasing to a mean length of 6.5 inches. Assuming continued good growth rates, bluegill recruitment to larger size categories can be expected. As with most bluegill fisheries, angler restraint and common sense are essential in maintaining quality of the fishery. Releasing larger bluegills in exchange for harvesting a few smaller ones is beneficial and helps to maintain quality angling. Walleye proved abundant in response to supplemental stocking and a sustained decline in northern pike numbers. Gillnet catches averaged 14.8 walleye/net. Most captures were less than four years old and not yet large enough to be keepers. Average length was 12.6 inches. With an additional year's growth, walleye fishing during the 2011-2012 angling season should be reasonably good. Northern pike abundance has continued to decline following the high water period of the late-90s. Growth of older pike is poor due to limited adult yellow perch numbers. There aren't many 30.0 inch and larger pike in the lake. Average length of pike measured in the gillnet catch was 21.9 inches.

Lake Irene continues to support a healthy northern cisco or tullibee population. The sustained presence of this coldwater species indicates water quality is relatively good.
