5-acre lake in San Juan County, Utah. The lake tops out around 18 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 5 acres, worked by 0.4 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 89% of this chart, as modeled. San Juan County claims this one. Its nearest charted neighbour, Lloyds Lake, is 6 mi to the southeast.
Come spring, look for rainbow trout tight to the bank in 5 to 18 ft. Through summer count on 5 to 18 ft; the winter hold is 4 to 18 ft. If you only fish one area, make it Break off the point: a drop-off around 8 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

| Spring | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
