Lake City conducts annual
monitoring (started in 1993) of aquatic habitat and fish populations in Navigation Pools 3, 5, 5a, 6, 7 and the MN portion of Pool 9 of the Mississippi River and also on the Lower Vermillion River (predominately backwaters).
- Objective: to maintain a “finger on the pulse” of an ever-changing system while increasing our long-term understanding and perspective of how climatic, geomorphological, and biotic variables affect habitat and fish populations in this portion of Upper Mississippi River
- Goal: use this information to help direct management decisions and actions that improve and/or protect habitat conditions, regulate commercial and sport harvest of fish, and recommend further research opportunities

- Sturgeon are pre-historic fish that have evolved in large river systems throughout the world.
- Populations have been threatened due to overfishing of the species for caviar production and secondarily by habitat reduction and pollution.
- The upper Mississippi River provides habitat suitable for lake and shovelnose sturgeon
- The Lake City fisheries crew began tagging lake sturgeon in the Mississippi River in the spring of 2007 to determine population abundance, size structure, and movement.
- Currently, 149 fish (between 13-63.5") have been tagged.
- Most were captured and tagged below Lock and Dam 3 (Red Wing).
- A similar tagging study is being conducted in Lake St. Croix. These "St. Croix" fish have been documented as far down as lower Lake Pepin.
