Stocking history
| Year | Species | Size | Number | Pounds |
|---|---|---|---|---|
| 2024 | Walleye | fry | 92,000 | 0.9 |
| 2022 | Walleye | fry | 92,000 | 0.8 |
| 2021 | Walleye | fry | 92,000 | 0.8 |
| 2018 | Walleye | yearlings | 86 | 43.0 |
| 2018 | Walleye | yearlings | 229 | 63.0 |
| 2018 | Walleye | fingerlings | 988 | 38.0 |
| 2016 | Walleye | fingerlings | 1,766 | 92.0 |
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.
Lake Henry is a small (152 acres), productive basin located within the Long Prairie River watershed. Mean and maximum depths are 13 and 32 feet, respectively. Lake Henry, along with lakes Agnes and Winona, comprise a chain of lakes within the city limits of Alexandria. Lakes Henry and Agnes are broadly connected with a common "narrows" area between the two basins. A shallow sand and rock bar separates the two basins. This bar is only one to two feet under the water surface during normal water levels. There is no public access on Lake Henry. Boaters access the lake via the public access on connected Lake Agnes, although that can be challenging when water levels are low. Boaters should note that motorized watercraft operation across Lake Agnes is regulated by a slow, no-wake restriction. Alexandria's City Park, which includes a public swimming beach, is located on the southeast shoreline of Lake Henry. The park also has a fishing pier that protrudes into connected Lake Agnes. A standard MN DNR lake survey was completed in summer 2023 to assess the fish community. Gamefish populations continue to expand in this basin as water quality and clarity continue to improve and aquatic vegetation becomes more abundant. The shallow, productive nature of this basin results in fast growth and larger average size for most gamefishes. A quality Largemouth Bass population was evident in 2023. This population is currently protected by a special 12- to 20-inch protected slot limit. All bass 12 to 20 inches in length must be immediately released with one bass over 20 inches allowed in possession. Panfish species commonly targeted by anglers include Black Crappie, Bluegill, and Yellow Perch. Black Crappie abundance has substantially declined in recent years due to a 2021 summerkill event that predominantly affected this species. Crappie fisheries are typically "boom or bust" in nature so hopefully this population recovers soon. Bluegill numbers have increased in recent years. The current population is characterized as moderate, in terms of both abundance and size structure. Yellow Perch are abundant. Harvestable-size perch are available but smaller fish tend to dominate this population. Northern Pike tend to exhibit lower abundance but larger average size on this basin. Record-high Walleye abundance was documented in 2023. Multiple year classes were sampled, with an average size of 17.9 inches and 2.2 pounds. Other fish species sampled in the 2023 survey included Green Sunfish, Pumpkinseed, and White Sucker. White Suckers were particularly abundant. The next lake survey is…
