| Recent studies on Bear Lake, Utah, indicated changes in plankton and nutrient levels in some shallow areas. A study of the littoral bottom invertebrates was initiated to determine possible differences in some communities. The study showed that some areas were affected by apparently eutrophic changes near shore and breakwaters. The most important environmental influences were increased amounts of silt and clay, organic matter, and consequent decreased concentrations of oxygen near the bottom. |
