Rating depth structure for brook trout.
Recent public catches load as you reach this section.
13-acre lake near Cody Region. The lake tops out around 18 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Lake Arden runs 11 acres with 0.6 miles of edge. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 53% of this chart, as modeled. You'll find it in Big Horn County. For a second option, Shell Lake lies 3 mi southeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 5 to 18 ft, wintering in 3 to 18 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 15 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
