Common questions
What fish are in Caldron Falls Reservoir?
Wisconsin DNR lists Musky as common on Caldron Falls Reservoir. Wisconsin DNR lists 5 species for the lake in total. Those are survey results, not a catch report: a net set on one date measures what was in that net.
When was Caldron Falls Reservoir last surveyed?

Is Caldron Falls Reservoir stocked?
No stocking record for Caldron Falls Reservoir appears in the Wisconsin DNR material on file. That is not the same as a confirmed unstocked lake: it means no stocking document was published for it in the records this page draws on.
Do the water-quality readings tell me how Caldron Falls Reservoir fishes?
A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Caldron Falls Reservoir’s water-quality measurements separately, and the water-quality trend over 3 years of monitoring is stable. Catch rate is not a swim clearance and is not a weekly bite report.
Before you eat what you catch
Water-quality readings are not a consumption advisory. Mercury and PCB advice for Wisconsin waters comes from WI DNR/DHS, and it is issued per species and per size class: a lake with clear, low-nutrient water can still carry a meal limit on larger predator fish.
