Privately Stocked Fish
* indicates privately stocked fish. Private stocking includes fish purchased by the DNR for stocking and fish purchased and stocked by private citizens and sporting groups.

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 08/13/2012)

Lake Le Homme Dieu is a 1,800-acre basin located on the northeast city limit of Alexandria. It is part of the Alexandria Chain of Lakes. Navigable connections exist to Lake Carlos and Lake Geneva. The shoreline and most of the watershed area are well developed. Water quality is very good. Water transparency measurements average 10 feet during summer months. Because of its clear water and close proximity to Alexandria, the lake is popular with anglers and recreational boaters. Boating pressure can be high on weekends during the summer. Two well maintained accesses are available to the public. Rotary Beach Access is located on the northwest shoreline off County Road 42. Krueger's Creek Access is located along the northeast shoreline. The City of Alexandria maintains a public swimming beach on the southeast shoreline. Boaters should be cautious of marked navigation hazards on the lake. A shallow rock bar is located in the middle of the lake off the west shoreline. Shallow rock areas are also present off both points leading into the west bay (Bugaboo Bay).

Lake Le Homme Dieu offers diverse and quality fishing experiences. Largemouth bass densities have decreased in recent years, but bass continue to be abundant. Largemouth bass grow slowly due to their high abundance and intense competition for a limited food supply. Fortunately they live for many years and with time can grow large. Bass captured during the 2012 electrofishing survey averaged 11.3 inches in length. The largest caught during the survey measured 16.8 inches. Larger bass are commonly caught by tournament anglers.

Bluegill density has also decreased with loss of very strong year classes established in the late-90s. This temporary decrease in abundance has resulted in improved growth. Even so, it takes a long time for bluegills to grow to 8.0 inches. Those large bluegills are at least 12 years of age. Average size of bluegills captured during the 2012 survey was 5.5 inches. Black crappies are presently abundant. Age and size distribution of the 2012 population sample describe a quality fishery. Eight age classes were documented in the gillnet catch. Most crappies captured were relatively young fish, thus average size was 7.5 inches. Due to the extended age distribution, 19% of all 5.0-inch and larger crappies measured exceeded 10.0 inches in length. The largest crappie caught was 12.1 inches in length.

Northern pike catches among the two most recent surveys have been lower than usual. Gillnet catches averaged approximately 6.0 fish/net. Lower abundance is desirable to improve predator/prey balance and productivity. Average size of pike caught during the 2012 survey was 22.4 inches. It is probable that the population sample under-represented numbers of larger pike. Northern pike is a cool water gamefish with limited tolerance of water temperatures exceeding 70 F. Lake Le Homme Dieu was thermally stratified at time of the August 2012 survey. It is projected that many larger pike were in deeper, cool water near the thermocline at approximately 29 ft. in depth. These fish were not very vulnerable to capture in gillnets. The largest pike captured measured 31.5 inches.

Walleye are stocked every year to supplement natural reproduction and increase abundance and fishing success. DNR stockings have been augmented with walleye fingerlings since 2007. These additional walleye were purchased and stocked by the Lake Le Homme Dieu Association and Viking Sportsmen, Inc. Gillnet catches during the 2012 survey averaged 8.6 walleyes/net. This catch rate was greater than that of the preceding survey, but well within the range of expected catch rates for similar lakes. Age distribution of the 2012 population sample was skewed towards young walleye, which suggests combined stockings have been successful in increasing numbers of small fish that may grow to a harvestable-size in the near future. It is also probable that contributions of stocking were enhanced by low, stable northern pike numbers and a significant decrease of largemouth bass density. Survival rate of young stocked walleye improved with less competition and predation. Size distribution of captured walleye ranged from 7.5 to 23.3 inches and averaged 14.1 inches.

Lake Le Homme Dieu is not as fertile nor does it have as great a carrying capacity as many other lakes in west-central Minnesota. Popular gamefishes such as bluegill, northern pike, and largemouth bass are abundant but they don't grow fast enough to optimize annual sustainable yields. At present, Lake Le Homme Dieu is top heavy with predators. Yellow perch abundance is too low to support high numbers of larger bass, northern pike, and walleye. Medium-size bluegills are too large to be consumed by most predators. Due to slow growth, many young predators are lost to natural mortality before growing large enough to harvest. Anglers are encouraged to harvest surplus numbers of small- to medium-size bass, northern pike, and bluegills to improve predator/prey balance and productivity of the fishery.

Zebra mussels were discovered in Lake Le Homme Dieu in 2009. They have since reproduced and colonized on aquatic plants and hard surfaces throughout the lake. Zebra mussels filter green alge and nutrients from the water. Their filtering of chlorophyll may result in an increase in water clarity. Loss of primary productivity and reduced zooplankton abundance and diversity may also disrupt the food chain and diminish gamefish production. Please comply with statewide regulation and practices to prevent spread of zebra mussels to un-infested waters.
