Mississippi River - U.S. Lock & Dam #1 Pool maps at 466 acres behind 11.6 miles of shoreline. With a shoreline index of 3.8, this water is all arms and coves — edge habitat well beyond its acreage. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Tip to tip the water measures near 5 mi with a 1.3-mi widest point. It sits in Hennepin County. If the bite dies, Powderhorn is 2 mi to the west.
Spring puts walleye in skinny water — 2 to 9 ft is the zone. Summer fish stay in 3 to 9 ft, and winter fish hold in 3 to 9 ft. Break off the point is the standout, a drop-off at roughly 4 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |

Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 3 to 9 ft in summer and finish the year down in 3 to 9 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
