Volunteer monitoring began at Echo Lake in 2001 and continued from 2003 through 2008. The data indicate that this city lake (Shoreline) is very lightly colored and is high in primary productivity (eutrophic) with fair water quality. More data are needed for trend analysis, but productivity appears to be steady over time.
Profile data indicate thermal stratification is stable through summer, and sedimentary phosphorus release adds to deep water concentrations. Nitrogen to phosphorus ratios dip below 20:1 in late summer through fall, which favors bluegreens over other algae, and they have been identified as common in the lake.
Echo Lake has no public access boat ramp, but car top boats may be launched from the city park. Residents should keep a watch on aquatic plants growing nearshore to catch early infestations of noxious aquatic 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:
