786-acre reservoir near Las Animas County. The lake tops out around 70 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 647 acres wrapped in 9.1 miles of bank. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 53% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 2.6 mi, about 0.8 mi across. It sits in Las Animas County. Its nearest charted neighbour, Lake Maloya, is 15 mi to the southeast.
