Minnesota Fond du Lac Chemistry from 1998-2011

This database includes 24 lakes located in the Fond du Lac Reservation in east central
Minnesota: 7 wild rice lakes, 8 lakes listed as ‘recreational/fisheries’ lakes, and
9 other lakes. The lakes have been monitored for this program from 1998 to present and they are
part of an ongoing program. This information is the basis for assessing water quality,
identifying impacts and stressors, restoration opportunities, and recommendation for additional
protection as “Outstanding Reservation Resource Water”. The lakes have been sampled
for chemistry (alkalinity, apparent color, chloride, chlorophyll a, color, dissolved organic
carbon, pH, total suspended solids, specific conductance, sulfate, true color); nitrogen
(ammonia, ammonia, nitrate+nitrite, total Kjeldahl); phosphorus (ortho, total); and Secchi
depth. The lakes were sampled monthly during the open-water season (approximately, May-October)
in the surface layer. See GIS shapefile for geographic information on the lakes
