  • ABSTRACT ROBINSON, JASON LESLEY. Discontinuities in Fish Assemblages and Efficacy of Thermal Restoration in Toxaway River, NC
    ABSTRACT ROBINSON, JASON LESLEY. Discontinuities in fish assemblages and efficacy of thermal restoration in Toxaway River, NC (Under the direction of Peter S. Rand) Biogeographical studies in the Toxaway and Horsepasture Rivers, (Transylvania County, NC) were initiated along with the creation of a state park in the area. This region is noted for extreme topographic relief, high annual rainfall totals and many rare and endemic plants and animals. The study area encompasses a portion of the Blue Ridge Escarpment and the associated Brevard Fault Zone. These geologic features are important factors in determining the distribution of stream habitats and organisms. I hypothesize that major waterfalls and cascade complexes have acted to discourage invasion and colonization by fishes from downstream. This hypothesis is supported by longitudinal fish assemblage patterns in study streams. Fish species richness in Toxaway River increased from 4 to 23 between Lake Toxaway and Lake Jocassee, a distance of 10 river kilometers. No species replacement was observed in the study area, but additions of up to 7 species were observed in assemblages below specific waterfalls. A second component of the research examines the efficacy of a rapid bioassessment procedure in detecting thermal and biological changes associated with a reservoir mitigation project in an upstream site on Toxaway River. The mitigation project began in the winter of 2000 with the installation of a hypolimnetic siphon to augment the overflow release with cooler water during summer months. I record a greater summer temperature difference on Toxaway River below Lake Toxaway (comparison of pre- vs. post-manipulation), relative to control sites.

    West Virginia Section 303(d) List and Supplements uunnamednnamed ttributaryributary ooff Elk-twoElk-two MMileile CCreekreek iinn KKanawhaanawha CCountyounty PPhotohoto bbyy PPatat CCampbellampbell The format of the 2004 Section 303(d) list is organized around the Watershed Management Framework. The fi ve hydrologic groups (A-E) of the framework provide the skeleton. Within each hydrologic group, watersheds are arranged alphabetically and impaired waters are sorted by stream code in their appropriate watershed. The information that follows each impaired stream includes the stream code, the affected water quality criteria, the affected designated use, the general cause of the impairment (where known), the impaired length (or, by default, the entire length), the planned or last possible timing of TMDL development and whether or not the stream was on the 2002 list. The cause of impairment is often unknown or uncertain at the time of listing and is so indicated on the list. The cause(s) of impairment and the contributing sources of pollution will be identifi ed in the TMDL development process. Many waters are listed, by default, for their entire length. In most cases, it is doubtful that the entire length of stream is impaired, but without further data, the exact length of impairment is unknown. Each listed stream will be revisited prior to TMDL development. The additional assessments performed in the pre-TMDL monitoring effort will better defi ne the impaired length. A West Virginia Watershed Management Framework map is provided to assist navigation within the list. A key is also provided to aid in the interpretation of presented information.

The proposed project will involve the construction of a 304-mile 42-inch natural gas pipeline in Virginia and West Virginia. The MVP pipeline will cross the United States Army Corps of Engineers (Corps) Pittsburgh, Norfolk and Huntington Districts regulatory boundaries. Approximately 164-miles of the proposed pipeline, approximately 132-miles of proposed access roads, and three (3) compressor stations are located within the Huntington District’s regulatory boundary in Monroe, Summers, Greenbrier, Nicholas, Webster, Braxton, Lewis, Harrison, and Wetzel Counties, West Virginia. The project has been assigned the following file number: LRH-2015-592-GBR. Please reference this number on all future correspondence related to this proposed project. The Corps’ authority to regulate waters of the United States is based on the definitions and limits of jurisdiction contained in 33 CFR 328 and 33 CFR 329. Section 404 of the Clean Water Act (Section 404) requires a DA permit be obtained prior to discharging dredged or fill material into waters of the United States, including wetlands.

WALCOTT, Director United States Geological Survey. 3 A GAZETTEER OF WEST VIRGINIA. HENRY GANNETT. DESCRIPTION OF THE STATE. The State of West Virginia was cut off from Virginia during the civil war and was admitted to the Union on June 19, 1863. As orig­ inally constituted it consisted of 48 counties; subsequently, in 1866, it was enlarged by the addition -of two counties, Berkeley and Jeffer­ son, which were also detached from Virginia. The boundaries of the State are in the highest degree irregular. Starting at Potomac River at Harpers Ferry,' the line follows the south bank of the Potomac to the Fairfax Stone, which was set to mark the headwaters of the North Branch of Potomac River; from this stone the line runs due north to Mason and Dixon's line, i. e., the southern boundary of Pennsylvania; thence it follows this line west to the southwest corner of that State, in approximate latitude 39° 43i' and longitude 80° 31', and from that corner north along the western boundary of Pennsylvania until the line intersects Ohio River; from this point the boundary runs southwest down the Ohio, on the northwestern bank, to the mouth of Big Sandy River.

  • Decision Rationale Total Maximum Daily Loads for the Upper Guyandotte River Watershed, West Virginia
    Decision Rationale Total Maximum Daily Loads for the Upper Guyandotte River Watershed, West Virginia __________________________________ Catherine A. Libertz, Director Water Division Date: _________ ______________ Decision Rationale Total Maximum Daily Loads for the Upper Guyandotte River Watershed, West Virginia I. Introduction The Clean Water Act (CWA) requires a Total Maximum Daily Load (TMDL) be developed for those waterbodies identified as impaired by a state where technology-based effluent limits and other pollution controls do not provide for the attainment of water quality standards. A TMDL establishes a target for the total load of a particular pollutant that a water body can assimilate and divides that load into wasteload allocations (WLA), given to point sources, load allocations (LAs), given to nonpoint sources and natural background, and a margin of safety (MOS), which takes into account any uncertainty. Mathematically, a TMDL is commonly expressed as an equation, shown below. 푇푀퐷퐿 = ∑푊퐿퐴푠 +∑퐿퐴푠 + 푀푂푆 This document sets forth the U.S. Environmental Protection Agency, Region III’s (EPA’s) rationale for approving 380 TMDLs submitted by the West Virginia Department of Environmental Protection (WVDEP) for total iron, total selenium, and/or fecal coliform bacteria in the Upper Guyandotte River Watershed. The TMDLs were developed to address impairments of water quality standards as identified on West Virginia’s section 303(d) list of water quality- limited segments. WVDEP electronically submitted the TMDLs in its report titled Total Maximum Daily Loads for the Upper Guyandotte River Watershed West Virginia (February 2021) (hereinafter referred to as the “TMDL Report”), to EPA for final review and action on February 26, 2021.
