<br /> Table 5. Load calculations for trace elements entering and leaving Dillon Reservoir for 1997 and 1998 based on regression analysis of the log of instantaneous flow
<br /> relative to the log of concentration
<br /> [kg/yr, kilograms per year; %, percent; total and dissolved loads for lead and cadmium are not included due to most of the data being censored. Dissolved molybdenum concentrations in
<br /> some cases were
<br /> reported as greater than the total molybdenum concentrations, which resulted in higher calculated loads of dissolved molybdenum in Tenmile Creek and in the Blue River below the dam.
<br /> All concentrations
<br /> were deemed accurate within laboratory method precision I
