The topography of an area determines the direction of stream flow and often is a primary influence on the geographic distribution of precipitation. View a detailed Oregon elevation map.
|Oregon Stream and River Levels|
The United States Geological Survey has a number of stream gages located throughout Oregon. These estimate stream levels, discharges and record them over time. This data is published on the web and many stations allow users to plot custom graphs. Get updated Oregon river and stream levels from USGS here.
|Oregon Stream and River Level Alerts|
The United States Geological Survey has a system that will send you an email message when flood levels are reached on any steam with USGS gaging equipment that you have selected. Sign up here to recieve Oregon stream and river level alerts.
|Oregon Water Publications|
The United States Geological Survey has a number of publications related to water use and water resources in Oregon. View the water resource publications for Oregon here.
|Oregon Waterfall: Multnomah Falls|
Multnomah Falls is the tallest waterfall in Oregon, with a total height of 620 feet. The source of the falls are underground springs in Larch Mountain, which feed Multnomah Creek. The creek flows to the Columbia River Gorge, where it spills over 2 tiers of steep basalt cliffs. The basalt at the top was more easily eroded, and this erosion is what caused the eventual formation of two tiers. The Benson Footbridge spans the lower falls at a height of 105 feet.
The United States Geological Survey publishes updated drought maps on their website. There you can view a map that shows where below normal 7-day average stream flow conditions were recently recorded. The maps are updated daily. Get a current Oregon drought map here.
The National Atlas Project has precipitation maps for Oregon and other states that you can view online or print for personal use. These maps show the average annual precipitation levels mapped across the state. View and print an Oregon precipitation map here. Precipitation maps prepared by the PRISM Climate Group at Oregon State University and the United States Geological Survey.
