The Arkansas River drainage basin lies south and west of the town of Leadville. The listed segments on this 303(d) listed portion of the upper Arkansas account for 163 miles of the 1,450 mile length of river. Many tributaries flow into the Arkansas River including Lake Creek, Chalk Creek, and Evans Gulch, which are also listed on the 1998 303(d) list for elevated metal concentrations.

The overall goal of Colorado's nonpoint source program is to restore to full use those waters, both surface and ground water, impaired by nonpoint sources, and to prevent future impairments to Colorado's waters, using an effective, efficient and open process that fully involves the public and brings together the necessary regulatory and non-nonregulatory authorities, agencies and programs.

This update to the 2000 Nonpoint Management Program is intended to provide the near-term framework for program actions over the next five years. The actions identified in this document will lay the foundation to accomplish the long-term goals of the program.
