Please access the USGS stream Flow website above. There is a link for Statewide Stream flow once you click
on a state from the map.
Stream gage levels in The United States, relative to 30 year average.
The Map will look like this. Just click on a state you prefer.
I clicked on Oregon and a Map of Oregon with dots for various streams will popped up.
Stream gage levels in Oregon, relative to 30 year average.
The Map looked like this. You can either click on the map or select Statewide Streamflow Table link to get
specific stream flow information for a site. Pick a site. I picked SILETZ River, OR.
Pick a time period and dates to graph. I would prefer if it were this weeks last 5 to 7 days. Now below the
hydrograph you will see statistics for that particular river system as shown below.
Using the information you collected please answer the following questions.
First save and upload your Hydrograph. Remember you need to use control – V or upload from desktop using the mountain star icon at the
top of the text box.
The table will look similar to the one above but have different numbers in the table, upload this table.
1. What is the name of the Streams e.g) OWYTHEE RIVER NR ROME OR
2. What units are used to describe Discharge?
3. What is the Min and Maximum Discharge for that stream? What is the Range in Discharge?
4. What is the Discharge now?
5. What appears to be the highest discharge for the time period you selected? How did that compare to the maximum discharge recorded
for that stream?
6. Find the stream on google Earth and paste it in also so we know the location.
