Volunteer monitoring began at Lake Lucerne in the 1980s and continued through 2008, with a gap in the early 1990s. The data indicate that this city lake (Maple Valley) is nearly colorfree and relatively low in primary productivity (high oligotrophic) with excellent water quality, which has remained steady over time.
Profile data suggest that thermal stratification is stable through summer, but sedimentary phosphorus release adds little to deep water concentrations. Nitrogen to phosphorus ratios in the upper water are above 20:1, which generally favors other algae species over bluegreens.
Lake Lucerne has no public access boat launch, but does have a history of both milfoil and hydrilla infestations for which eradication efforts have been underway since 1995. The last identified hydrilla plant was found in 2004. Lake users and residents should keep a close eye on aquatic plants growing nearshore to catch new or expanding patches of these and other noxious weeds.

This map shows the area of the watershed relative to the area of the lake. Generally speaking, the larger a watershed is relative to a lake, the greater the influence land use practices on lake water quality

A common method of tracking water quality trends in lakes is by calculating
the “trophic state index” (TSI) (Carlson, 1977). TSI indicators predict the biological
productivity of the lake based on water clarity (Secchi) and concentrations of total
phosphorus (TP) and chlorophyll a (Chlor).
The average of these three TSI indicators during the growing season can be used
to place lakes in one of three broad categories:
