Solomon River Basin TMDLs

• TMDLs for the Solomon Basin
• Implementation Priority
• August 7, 2003 Approval Letter
• September 30, 2003 Approval Letter
• January 21, 2004 Approval Letter

KDHE has completed the first round of TMDLs within the Solomon Basin based on the 1998 and 2002 – 303(d) lists. There are 21 approved TMDLs within the Solomon 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 Solomon Basin in 2009 and 2014.

The 2008 - Section 303(d) list submitted to and approved by EPA identifies watersheds associated with 15 stream chemistry sampling stations as water quality impaired. There are three lakes in the Solomon River Basin listed as water quality impaired. Among the streams: dissolved oxygen depletion, total suspended solids, and total phosphorus cause the greatest numbers of impairments. Other pollutants limiting the use of the Solomon River Basin streams include arsenic, biological stressors, copper, E. coli bacteria, and sulfate. Among the lakes: eutrophic conditions indicative of excessive algae production, siltation and arsenic are the causes of impairment. Each parameter causing impairment requires a TMDL.
