. Study Framework 4 Tributaries were first sampled in Spring and Fall 2000 for fish populations using triple pass electroshock Benthic macro-invertebrate and water chemistry were sampled biannually each year since April and October 2010 fish populations were re-sampled for taxa and population changes East Lynn Lake Sampling Creeks Mining Activity Google 2010 Sampling Tributaries Big Laurel Creek Trough Fork East Fork Twelvepole Creek Google 2010 Kiah Creek Mining History Small scale mining began in 1982 Large scale mining began in 1987 50% Deep / 50% Surface Approximately 2 million tons of coal are produced each year in this area Impacts: Coal Prep Plant, Refuse Fill, Slurry Impoundments, Haul Roads, Further Impacts: Logging (roughly 5,000 acres), 250 Oil/Gas Wells with pipelines Stream Health Evaluation Methods and Comparison SAMPLING: Triple pass electroshock (Backpack) COMPARISON: 2000/2010 Fisheries Index of Biotic Integrity 2000→2010 Bi-annual West Virginia Stream Condition Index Macro-invertebrate Assemblage Trend analysis- combined fall/spring scores 2000 → 2010 Biannual Water Chemistry Sampling Conductivity Trend analysis- combined fall/spring values Macroinvertebrate Assessment West Virginia Stream Condition Index (WV-SCI) Regulatory management/Permitting WVDEP Core Metrics EPT taxa (mayfly, stonefly, caddisfly) Total taxa % EPT WV-SCI Range % Chironomidae 78.01 to 100 % Top 2 Dominant taxa 68.01 to 78.00 HBI (Family Biotic Index) 60.61 to 68.00 45.01 to 60.60 22.01 to 45.00 0 to 22.00 Rank “Very Good” “Good” “ Grey Zone” “Slightly Impaired” “Moderately Impaired” “Severely Impaired” Impairment Not Impaired Impaired Fisheries Assessment Index of Biotic Integrity (IBI) (0-100 Scale) Based on KY-IBI Core Metrics IBI Score Rank > 71 59-70 39-58 19-38 0-18 Excellent Good Fair Poor Very Poor Native Taxa Richness Darter, Madtom, and Sculpin Richness Intolerant Species Richness Simple Lithophilic Spawning Species Richness Relative Abundance of Insectivorous Individuals Relative Abundance of Tolerant Individuals Relative Abundance of Facultative Headwater Individuals Drainages < 6 square miles Conductivity Levels 10 Year Conductivity Average - Biannual Sampling 1400 1200 1000 s 800 600 400 200 0 Trough Fork 1 Big Laurel Creek Kiah Creek East Fk.
