Results from subwatershed where monitoring continued in 2007: 
Preliminary results from 2007 monitoring are provided in the enclosed
document.  Included are residue data (atrazine and TSS), flow and
weather data, and assessment of the atrazine residue results relative to
the screening threshold  levels of concern (CASM_Atrazine LOC and
threshold rolling average triggers).  The results show no exceedances of
any LOC in 2007, including in 5 monitored sites within the unique
Missouri Major Land Resource Area 113 (characterized by high percentages
of vulnerable soils along with the presence high slopes and an unusually
continuous and shallow claypan layer).
