A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades West Sylvia Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2025-07-21 survey
A targeted survey of nearshore fish species in West Lake Sylvia was conducted on July 21, 2025 by Sauk Rapids fisheries 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 electrofishing was…

Common questions
What fish are in West Sylvia Lake?
Minnesota DNR surveys at West Sylvia Lake average 28.83 largemouth bass per unit of sampling effort (CPUE) across 13 surveys. The most recent is a Targeted Survey dated July 21, 2025. Length samples in the latest survey that recorded them ran 4–21 inches. Minnesota DNR lists 15 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 West Sylvia Lake last surveyed?
The most recent fisheries survey on file for West Sylvia Lake is dated July 21, 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 West Sylvia Lake stocked?
Minnesota DNR publishes a stocking history for West Sylvia 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 West Sylvia Lake fishes?
A DNR fisheries survey reports fish abundance and catch rates, not a water-quality grade. LakeQuality grades West Sylvia Lake A from EPA Water Quality Portal chemistry, and the water-quality trend over 6 years of monitoring is declining. 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.
