Elmo Lake FishingAWater-quality grade A
Minnesota DNR surveys at Elmo Lake average 11.55 largemouth bass per unit of sampling effort (CPUE) across 18 surveys. The most recent is a Targeted Survey dated August 6, 2025. Length samples in the latest survey that recorded them ran 14–14 inches. In Washington County, Minnesota, Elmo Lake carries an overall water-quality grade of A. Water clarity averages 11.1 feet of visibility, and there is one public boat landing. The survey figures on this page are Minnesota DNR's own; the water-quality grade comes from EPA Water Quality Portal samples. Neither is a forecast of today's bite.

Top Species by Catch Rate

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE means more abundant in standardized sampling. This is not a weekly bite report.

From the 2025-08-06 survey
A targeted survey of nearshore fish species in Lake Elmo was conducted on August 6, 2025, by Lake Biological Monitoring and Assessment program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack…

Common questions
What fish are in Elmo Lake?
Minnesota DNR surveys at Elmo Lake average 11.55 largemouth bass per unit of sampling effort (CPUE) across 18 surveys. The most recent is a Targeted Survey dated August 6, 2025. Length samples in the latest survey that recorded them ran 14–14 inches. Minnesota DNR lists 13 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 Elmo Lake last surveyed?
The most recent fisheries survey on file for Elmo Lake is dated August 6, 2025. Survey intervals vary by lake and by species; a gap of several years between surveys is normal and does not mean the record is missing.
Is Elmo Lake stocked?
Minnesota DNR publishes a stocking history for Elmo Lake. It records which species were released, in what numbers and in which years — the source documents are linked further down this page. A lake can be stocked in some years and not others, so read the years rather than assuming an annual release.
Does the water-quality grade tell me how Elmo Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades Elmo Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 5 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
A water-quality grade is not a consumption advisory. Mercury and PCB advice for Minnesota waters comes from MDH, and it is issued per species and per size class — a lake can grade well and still carry a meal limit on larger predator fish.
