Cimarron Basin TMDLs

• TMDLs for the Cimarron Basin
• Implementation Priority
• Approval Letters

KDHE has completed the first round of TMDLs within the Cimarron Basin based on the 1998 -303(d) list. There are 10 approved TMDLs within the Cimarron Basin that describe the strategies and goals to reduce pollution to achieve water quality standards. Of these, there are two that are high priority for implementation. KDHE develops TMDLs on a basin-by-basin approach and will revisit existing TMDLs and develop new TMDLs within the Cimarron Basin in 2011.

The 2008 - Section 303(d) list submitted to and approved by EPA identifies watersheds associated with four stream chemistry sampling stations as water quality impaired. There are four lakes in the Cimarron River Basin listed as water quality impaired. Among the streams: high temperatures, chloride, selenium, total phosphorus and sulfate cause the impairments. Among the lakes: eutrophic conditions indicative of excessive algae production, fluoride and sulfate were the causes of impairment. Each parameter causing impairment requires a TMDL.
