• NE'4 Section 12, TSN, R86W) vas 1.1 km (0.7 miles) downstream of <br /> Station 2 and below all previous coal mining activity. <br />Sampling at the two stations established on Fish Creek during <br />the summer of 1980 vas also ceased in 1982. Station 1 (NW'z SE'z <br />Section 2, TSN, R86W) was located upstream of Energy Tipple No. 3. <br />Station 2 (NW's NE'Z Section 1, TSN, R86W ) was located 2.4 km (1.5 <br />miles) downstream of Station 1 and below the loadout facility. This <br />station vas sampled previously in 1975 (Dames and lioore, 1975) and <br />1979 (ERT/Ecology Consultants, Inc. 1979). <br />Location and degree of cover of aquatic macrophytes were mapped <br />in 100m sections at all stations ezcept Station 1 on Biddle Creek, <br />• where a 50m section was mapped. The Visual Estimate technique vas <br />used to obtain eztent of coverage. <br />Benthic invertebrates of Middle Creek and Fish Creek were <br />collected August 1-2, 1980. Two samples in the riffle sections of <br />each station were taken with a Subver square-foot bottom sampler <br />(mesh size 700 um). Pool habitat vas sampled by taking two Elkman <br />grabs. Each grab vas placed in a sieve bucket (mesh size 250 um) <br />and rinsed of ezcess silt and debris. Benthic samples were <br />preserved in the field with 75x ethanol and returned to the Lab <br />where the organisms were sorted from the debris, identified and <br />counted. The Shannon-Wiener Diversity Indea (D) vas caluclated for <br />• the invertebrates using the formula found in Weber (1973). <br />2.04-92 <br />
