S. Forest Service is planning to do a macroinvertebrate study of areas within the White River National Forest on April 7, 1989, and we feel that the study will afford useful information. The study will involve sampling at several points (indicated below) under the direction of a U.S.F.S. biologist. The samples will be sent to a lab for analysis , to determine macroinvertebrate population, alkalinity and pH. We are advised by the Forest Service in our discussions with them concerning this study that sediment, including how much is on the stream bottom and its effects, is a factor affecting the macroinvertebrate population. The sites to be sampled are: Coal Creek, above and below the wash plant. Crystal River, above and below coal Creek. Roaring Fork, above and below Aspen. Lincoln Creek, above Aspen. Mid-Continent does note, however, that while the study -offers information as to the quantity and quality of the macroinvertebrate populations, Coal Creek and the Crystal River below the Coal Creek confluence are subject to high sediment loads from snowmelt and precipitation events running over natural dirt and rock formations, separate from any possible sediment loading from Mid-Continent ' s mining operations. it will be difficult to establish, in any known scientific manner, that such
