Volunteer monitoring began at Lake Leota in 1998 and continued through 2008. The data suggest that this city lake (Woodinville) is lightly colored and moderate in primary productivity (mesotrophic) with good water quality. A trend of increase in productivity since 2002 has a moderately good correlation value.

Profile data suggest that thermal stratification is stable through summer, and sedimentary phosphorus release adds significantly to deep water concentrations. Nitrogen to phosphorus ratios in the upper water are above 20:1 early in the summer but decline in late summer, which generally favor bluegreens over other algae species.

Lake Leota has no public access points, though residents should keep an eye on aquatic plants growing nearshore to catch early infestations of noxious aquatic weeds. Lake Leota has recently experienced aggressive growth by a milfoil identified as the native species Myriophyllum verticillatum.

Maps


This bathymetric map shows contour lines of equal depth, similar to a topographic map would for mountains and valleys		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

Water Quality Data

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.

Chart Data
Use the charting tool to look at graphs showing single parameters for a single water year at a time.

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).
