Volunteer monitoring began at Tuck Lake in 2007 and continued through 2008, after which it was discontinued. The data indicated this lake was moderately colored and high in primary productivity (eutrophic) with fair water quality.
Profile data show thermal stratification was constant through summer, but sedimentary phosphorus release added only a small amount to deep water concentrations. Nitrogen to phosphorus ratios in the upper water were often below 20:1, which can favor bluegreens over other algal species. In 2008 a highly toxic bloom of Microcystis was identified, which persisted from late summer through December.
Tuck Lake currently has no public access, but residents should keep a close eye on aquatic plants growing nearshore to catch early infestations of aquatic noxious weeds such as Eurasian watermilfoil or Brazilian elodea.

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

Through a combination of efforts by volunteer lake monitors and King County staff,
data relating to physical, chemical, and biological aspects of the lake have been
collected for most lakes. The King County Lake Stewardship Program analyzes data
to track long-term water quality trends in small lakes in western King County.

Five year water quality trends
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:
<40 = oligotrophic (low productivity),
40 to 50 = mesotrophic (moderate productivity)
>50 = eutrophic (highly productive).
