This situation seriously limits the ability of Oregon's economy to grow and threatens the long-term sustainability of the natural systems our economy relies upon. Inadequate streamflows cause major problems for Oregon's rivers and the people who use them. Low flows can make it virtually impossible for a river to sustain healthy populations of fish and other aquatic life. Inadequate streamflows also limit river recreation, such as fishing, swimming and boating. They also contribute to water quality problems, since higher flows tend to dilute pollutant concentrations and lower stream temperatures.
High temperatures are lethal to fish.
These problems are common, even in Oregon's most prized rivers. Oregon withdraws over 8 billion gallons of water per day for all of its uses. This amounts to 3,000 gallons per day for every person in the state, which is the 7th highest water usage rate in the nation. Oregon's Water Rights System Under Oregon law, all the waters of the state belong to the public. A water right nearly always specifies the amount of water that can be taken, where the water must be withdrawn, where it can be used, and for what purpose.
