of G. robusta (as in May's 1970 thesis); this was probably an error in transcription or the result of some taxonomic confusion. Aquatic inverte- brates reported from the White River included mayflies, true flies, caddis- flies, stoneflies, beetles (Coleoptera), dragonflies and damselflies (Odonata), oligochaete worms (Plesiopora), amphipod crustaceans, pulmonate snails and leeches identified to family or genus. Specific collection sites and numbers of specimens were not included. Studies coordinated by Thorne Ecological Institute and conducted in the Piceance Creek Basin (Regional Oil Shale Study) included peripheral reference to the White River near Piceance and/or Yellow Creeks. Pennak (1974) reported on summer limnological conditions. True flies, mayflies, caddisflies and stoneflies were found at all stations and were identified to genus. Benthic animal productivity was generally low. Organic lithophyton productivity was unusually high. Wilbur (1973 and 1974) presented data on temperature, pH, dissolved oxygen, elemental concentrations, chloride, hard- ness, nitrate, phosphate, fluoride, and conductivity. Pettus (1973 and 1974) collected fishes from White River stations by electrofishing, angling, and seines. Fishes collected from White River were mottled sculpin, speck- led dace, mountain whitefish, carp (Cyprinus car io), flannelmouth sucker, bluehead sucker, rainbow trout, brown trout and fathead minnow (Pimephales promelas). White suckers (Catostomus commersoni) were also reported from the White River and Piceance Creek, but they have not been found in these streams by any other investigator. In 1974, the consulting firm of Woodward-Envicon began studies re- ported to the Area Oil Shale Supervisor of the U.S. Geological Survey (Ashland Oil, Inc. and Shell Oil Co. 1975-76) on findings related to the 6
