Cold Springs Lake vs Viking Lake

Water quality, depth, fish species, and recreation comparison.

Cold Springs Lake has a higher water quality grade (D, Poor) than Viking Lake (F, Very Poor). Both are in Wisconsin.

Cold Springs Lake and Viking Lake are both in Iowa — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. These two are within a letter of each other on the rubric — Cold Springs Lake (D) versus Viking Lake (F). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.

With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
