| Abstract |
A study was conducted at sampling sites on four streams in the Piceance Basin of northwestern Colorado to acquire data on benthic macroinvertebrate communities prior to commencement of oil shale mining and processing activities. Piceance Creek, the major stream studied, exhibited considerable longitudinal variation in environmental conditions. Sodium, sulfate, chloride, and total dissolved solids increased greatly in the downstream direction. The temperature range, turbidity, severity of winter ice conditions, and effects of grazing and irrigation activities also increased downstream. Downstream reductions in density, biomass and diversity, and altered macroinvertebrate species composition were associated with the longitudinal changes in environmental parameters. Effects of oil shale mining and processing activities on aquatic biota will depend upon the type of mining employed, the extent of surface and subsurface disturbance, the success of pollution controls, points of pollution entry, and extent of water depletion. Present environmental conditions and macroinvertebrate communities of lower reaches of Piceance Creek may be indicative of the potential effect of future impacts at upstream locations. |
