MONITORING STUDY FY08
Monitor or Propose 303(d) Listing
The Trempealeau River at Dodge has been monitored for the past several years as a LTT network site. The median total phosphorus concentration at the site is 369 ug/L which is the highest amoung the 42 LTT sites. Concentrations of bacteria, suspended solids and dissolved silica are amoung the highest of other LTT sites. Very limited biological data has been collected from the river and the extent of high phosphorus concentrations are not known. Another unknown, is the impact the high phosphorus concentrations are indirectly having on the biological community.
