Volunteer monitoring began at Lake Boren in the 1980s and continued through 2008, with several gaps in the record. The data characterize this city lake (Newcastle) as lightly colored and moderate in primary productivity (mesotrophic) with good water quality. There is a possible decreasing trend from 1994 through 2008 in productivity, but the data correlation is not strong.
Limited data suggest that thermal stratification is stable through the summer, and sedimentary phosphorus release adds to deep water concentrations. Nitrogen to phosphorus ratios were occasionally below 20:1, which favors bluegreens over other algae. Bluegreens are commonly present in the lake, but no toxic strains have been identified to date.
Lake Boren has a car top boat launch area in the city park. Residents and lake users should watch the nearshore for noxious aquatic weeds, such as Brazilian elodea or Eurasian watermilfoil.

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:
