ABSTRACT

Resource Trend Analysis water quality and sediment sampling in
Pool 26 of the  Upper Mississippi River System was initiated in
August 1988 as part of the Long Term Resource Monitoring Program. 
Water quality sampling from 17 locations began during the first
week of August.  Over 2000 water quality measurements were made
under the Resource Trend Analysis component of the Long Term
Resource Monitoring Program on Pool 26 during the sampling
period, August 1, 1988 through October 31, 1988.  The Illinois
River had higher conductivity and turbidity and lower
transparency than other sites.  Velocity and dissolved oxygen
were also usually lower in the Illinois River.  These differences
may effect water quality parameters in the Mississippi River
below its confluence with the Illinois River.  Water clarity was
very good throughout the study period, indicative of stable flows
and low inputs from the drainage basin.
