<br />the standard for fecal coliform bacteria. The source of fecal contamination and the extent of <br />contamination above and below the sample point is unknown at this time, so further monitoring will <br />be planned to identify the sources. The Blacks Fork below the Granger WWTP has also been slated <br />for re-evaluation of the TMDLs for ammonia, fecal coliform and chlorine associated with routine <br />renewal of the discharge permit. <br /> <br />o <br />1'\.) <br />--l <br />W <br /> <br />In the same area, the Smiths Fork is proposed for listing after DEQ monitoring determined <br />the stream was only partially supporting its aquatic :life uses as a Class 2 water due to loss of <br />biological integrity and physical degradation of the stream. Smiths Fork from the confluence with <br />the Blacks Fork upstream an undetermined distance is also proposed for listing because fecal <br />coliform monitoring showed the stream was not meeting its use for contact recreation. Additionally, <br />a reach o(the Smiths Fork below the Mountain View WWTP is scheduled for are-evaluation of the <br />TMDLs for ammonia, fecal coliform and chlorine associated with routine renewal of the discharge <br />permit. <br /> <br />Haggarty Creek is the site of an inactive copper mine, the Ferris-Haggarty/Osceola Tunnel, <br />which dates from 1898. Haggarty Creek originates near the Continental Divide and confluences with <br />Lost Creek-to form West Fork Battle Creek. Haggarty Creek has been on past 303(d) lists due to <br />metal exqeedences (primarily copper with less toxic amounts of silver and cadmium) discharging <br />from the ;Ferris-Haggarty Mine. Review of data during the TMDL process on Haggarty Creek <br />revealed that copper standards are also exceeded on the West Fork of Battle Creek, downstream of <br />Haggarty Creek, so this stream is proposed to be added as a priority on the 303(d) List. <br /> <br />In addition to the priority impairments mentioned above, there are a number oflower priority <br />activities in the Green and Little Snake Basins to address various water quality issues. In the Green <br />River Basin, Reardon Draw had a watershed improvement project in place to correct physical <br />degradation of the stream channel, which reportedly was threatening aquatic life use support and <br />impacting the Green River. Because there has not been a report documenting water quality <br />improvements, the lower three miles of Rear don Draw is on Table C of the 303( d) List and the Green <br />River below Reardon Draw has been scheduled for monitoring. <br /> <br />The East and West Fork of Smiths Fork, and Willow Creek above the Blacks Fork were <br />placed on Table C of the 1998 303( d) List due to threats of aquatic life use support due to physical <br />degradation of the stream channels. Currently, a Section 319 watershed improvement project is in <br />place to improve the physical condition of the stream channels and riparian areas. <br /> <br />In the Little Snake Basin, recent monitoring indicates that aquatic life uses are fully supported <br />on the portions of the Savery Creek and North Fork Little Snake drainages within the National Forest <br />and much of the upper watershed of Little Savery Creek. However, physical degradation of lower <br />Savery Creek and Loco Creek is threatening full aquatic life use support, and these streams are on <br />Table C of the 303( d) List. Currently, a Section 319 watershed improvement project is in place in <br />the lower Savery Creek drainage to address those threats. <br /> <br />4-30 <br />
