Upper Republican Basin TMDLs

• TMDLs for the Upper Republican Basin
• Implementation Priority
• August 7, 2003 Approval Letter

KDHE has completed the first two rounds of TMDLs within the Upper Republican Basin based on the 1998, 2002, and 2004 - 303(d) lists. There are 11 approved TMDLs within the Upper Republican Basin that describe the strategies and goals to reduce pollution to achieve water quality standards. Of these, there is one that is high priority for implementation. KDHE develops TMDLs on a basin-by-basin approach and will revisit existing TMDLs and develop new TMDLs within the Upper Republican Basin in 2009 and 2014.

The 2008 - Section 303(d) list submitted to and approved by EPA identifies watersheds associated with five stream chemistry sampling station as water quality impaired. Among the streams: arsenic, dissolved oxygen depletion and total phosphorus are the causes of impairment. Each parameter causing impairment requires a TMDL.
