Aquatic Analysis for the ConaCat Environmental Assessment Jim Herrig 3/2014 Introduction The ConaCat Environmental Assessment has the potential to impact aquatic species within its analysis area. This document analyzes the effects to aquatic habitats and to aquatic species known to occur within the analysis area. It also analyses effects to certain rare aquatic species whose range falls within the analysis area, have suitable habitat present, but have not been documented in the analysis area.

Impacts to these species were evaluated for each alternative in this EA. Scope of Analysis The analysis area for aquatic resources includes all of the streams within the EA analysis area plus it extends approximately 5 miles downstream in the Tellico River from the confluence with Lyons Creek and 5 miles downstream in Conasauga Creek from the confluence with Hatter Branch. Effects to aquatic resources (primarily sediment), from all alternatives, are expected to return to pre-implementation conditions within three years (Swift 1985). Aquatic Habitats Existing Condition Streams in the Conasauga/Wildcat Watersheds drain to Hiwassee and Tellico Rivers. The aquatic habitats in this assessment area are composed of approximately 454 miles of ephemeral, intermittent and perennial streams (Table 1). The analysis area for aquatic resources extends approximately 5 miles downstream in the Tellico River from the confluence with Lyons Creek and 5 miles downstream in Conasauga Creek from the confluence with Hatter Branch. Effects to aquatic resources (primarily sediment), from all alternatives, are expected to return to pre- implementation conditions within three years (Swift 1985). Table 1 Stream miles in the Analysis Area Type of Stream Miles Ephemeral 282 Intermittent 94 Perennial 78 Approximately 25 miles of Forest Service managed streams are capable of supporting fish (11.5 miles of cool water communities and 13.7 miles of cold water communities) and are displayed in Table 2 along with their physical characteristics.

The main source for years was the Off Highway Vehicle area in North Carolina but that has been greatly stabilized following its closure in 2009. Laurel Creek which enters the Tellico River across from the Miller Mine Prescribed Burn Unit has had sediment issues recently. The occasional muddy water appears to be coming from private property in the Miller Ridge vicinity. No sedimentation problems were found in any of the other streams surveyed. There are fifty-seven species of fish present (Table 3) in this analysis area (Cherokee National Forest 2014); four are federally listed as Threatened or Endangered; two are Sensitive; and one is Locally Rare. The Forest Viability Goal for these species is to protect their habitats and restore their populations. Seven species are managed as game fish and their Viability Goal is to enhance their numbers. Rainbow and brown trout were intentionally introduced and are managed as game species. Thirty-nine fish are native species with a management goal of maintaining their populations. The last two species are all non-natives that have been introduced. The carp and yellow perch were not intentionally introduced and are considered too well established to control their spread. The Forest has no management objective for them. The Junaluska salamander is a Sensitive species found in three streams in the analysis area. There are five Sensitive aquatic insects that could be present based on the aquatic habitat conditions.
