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 07/28/2008)

East and West Sylvia Lakes are located in western Wright County, near the Town of South Haven. The lakes are connected by a navigable channel with a combined acreage of 1,524. They are also among the deepest lakes in the county at 78 and 97 feet deep for the East and West lakes, respectively. Water quality is excellent. Not surprisingly, they are very popular for recreational use during the open water season. Over 1,000 boats were counted at docks in 2002, and during summer weekends the public access on West Sylvia Lake is often very busy.

East and West Lake Sylvia is well suited for largemouth bass because of good water clarity and diverse aquatic vegetation. The average catch rate for night electrofishing in area lakes is 63/hour and West Lake Sylvia was 70/hour in 2008, which was less than the rate of 300/hour sampled in 2002. The population was dominated by smaller fish (8-12 inches), while bass over 16 inches were rare. The percentage of fish larger than 12 inches was 23%.

Walleye management in Lake Sylvia requires regular alternate year stocking of fingerlings, since natural reproduction does not occur. The population of walleye between 16-28 inches was estimated to be 1,089 (0.7/acre). The walleye catch rate has decreased since 1992. Growth rates are relatively slow, but can vary greatly among individuals. Individual walleye may reach a large size in East and West Lake Sylvia.

In 2008, catch rates for northern pike were above the range that is normal for lakes like East and West Sylvia. Northern pike up to 34 inches were sampled, but most of the fish were 16-20 inches. Average weight was less than two pounds. Only 12% of northern pike were larger than 24 inches. Catch rates and average size have remained consistent for East and West Lake Sylvia over the past three decades. Based on the small average size of northern pike it is expected that anglers harvest only one of every 10 fish caught. Similar results have been found at nearby Sugar and Pulaski Lakes. New regulations for northern pike will go into effect in 2009: a 24-36 inch protected slot limit and three fish daily bag with only one over 36 inches allowed.

Bluegill were sampled in numbers that were typically found in similar lakes. Bluegill grow slowly, based on age estimates made from examining otoliths. Seven-inch bluegill were nine years old. About one percent of the population is larger than eight inches.

Few black crappie were captured during summer netting because crappie use deeper water during this time of year. During ice-out netting (4/3  5/2/2008), a much larger number of crappie were sampled at a rate of 5.6/net. The average size was 9.8 inches and crappie up to about 13 inches were observed. Growth was above that for similar lakes, but rates were based on only a few individuals.

Other fish caught were black, brown and yellow bullhead; green, hybrid and pumpkinseed sunfish; bowfin; rock bass; yellow perch; and white sucker.

The clear water of the lakes supports a diverse plant community, out to depths of 23 feet. Stands of emergent and floatingleaf vegetation are present, but primarily in shallow bays or other sheltered areas. Eurasian water milfoil was found in both East and West Sylvia Lakes for the first time in the spring of 2008.
