| Nutrients | 2002 | Sep-29-2011 | Applicable WQS attained; original basis for listing was incorrect. | 6/2/2010 (NED) - During the development of the Weiser River Subbasin Assessment and TMDL, approved 01/19/2007, diel monitoring was conducted which did not indicate an exceedance of the dissolved oxygen criteria nor was nuisance aquatic growth detected by dissolved oxygen. Therefore, it has been determined that nutrients are not impairing the designated uses in the lower Weiser River. Refer to page 92 of the TMDL for additional information. |
