 | | Pend Oreille Lake, with a maximum depth of 1200 feet, is the fifth largest natural freshwater lake in the United States. |
 | | The 100,000-acre, 40-mile long Pack River is the second largest tributary to Lake Pend Oreille, but contributes the highest per-acre loading of nitrogen and phosphorous to the lake. |
 | | Besides nutrient pollution, the Pack River suffers from high water temperatures, low levels of dissolved oxygen, and excess amounts of fine sediment which are negatively affecting drinking water, agricultural water, and heavy recreational uses of the river, as well as endangered Bull Trout. |
