During a rainstorm, particles from the surrounding land are washed into the river making the water a muddy brown color, indicating water that has higher turbidity values. Turbidity can provide food and shelter for pathogens. Columbia River DART provides an interactive data resource designed for research and management purposes relating to the Columbia Basin salmon populations and river environment. The highest and most recent high lake cycle began about 25,000 years ago and produced Lake Bonneville, a huge lake over 1,000 feet deep that extended over most of northwestern Utah and into Nevada and Idaho. Turbidity is the clarity of water and it is an important factor in water quality.

Estuarine turbidity maxima (ETM) function as hotspots of microbial activity and diversity in estuaries, yet, little is known about the temporal and spatial variability in ETM bacterial community composition. Many industries along the river have historically ceased operations at this level. These materials are typically in the size range of 0.004 mm (clay) to 1.0 mm (sand). The Columbia River LOBO, a component of the K: Kelt, downstream migration for steelhead having already completed migration at least once, i.e., observed in expected basin as adult or tagged as adult. Other water, such as the creek behind your house after a rainstorm, is likely to be highly turbidbrown with floating sediment. individuals who consume as a substantial part of their diet, whitefish and other bottom feeding fish of the Columbia River caught in the vicinity of the plant.
