314-acre pond near North Dakota. North Dakota Game & Fish survey water. The lake tops out around 15 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
Mosher WPA maps at 314 acres behind 2.6 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. End to end it runs roughly 0.9 mi, about 0.7 mi across. Barnes County claims this one. If the bite dies, Lake Ashtabula is 4 mi to the southeast.
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Summer fish stay in 5 to 15 ft, and winter fish hold in 5 to 15 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 11 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
