Abstract
The effects of saline seeps on the biota of five small reservoirs in north-central Montana were studied. It was determined that the saline seeps cause increases in the amounts of TDS, conductivity, heavy metals, nutrients, chlorides and sulfates in the reservoir. The benthic fauna exhibited taxonomic changes from reservoir to reservoir. This was probably a result of the varying degrees of salinity found. The most probable cause for the elimination of fish from the reservoirs was the increase in total dissolved solids. At the time of the study the streams flowing from the study area were not affected by the saline seeps. However, the amount of salts, etc. in the streams could increase after a rainfall and be discharged to the Missouri River.

Contents Notes
"At the request of the Montana Department of Health and Environmental Sciences, a biological and chemical investigation of saline seep affected farm ponds on the Highwood Bench area of Montana was conducted from June 13 to 19, 1974 by personnel from the National Field Investigations Center - Cincinnati of the U.S. Environmental Protection Agency and Region VIII EPA. The purpose of the study was to determine the effect of the saline seeps on the biota of five small reservoirs in the Highwood Bench and to ascertain whether surface waters flowing to the Missouri River are degraded by an influx of saline waters. The water bodies studied were Tunis Reservoir (used as a control and not actually situated on the Highwood Bench), Booth Reservoir, Bramlette Reservoir, Birkland Reservoir and Hanford Reservoir."--Page 1.
