The Dalles High School

 The Dalles High School (TDHS), formerly The Dalles Wahtonka High School (TDW) is a public high school located in The Dalles, Oregon, United States. It houses students from both The Dalles and the adjacent town of Mosier.

History
In 2004, North Wasco County School Districts 9 and 12 combined to form one school district in The Dalles: SD 21 (this number being chosen as it is the sum of 9 and 12). School District 21 immediately combined Wahtonka High School and The Dalles High School into "The Dalles Wahtonka Union High School". Later the "Union" was dropped, shortening the name to "The Dalles Wahtonka High School".

In 2012, the Oregon State Board of Education adopted a rule to ban the use of Native American names and imagery for use in school mascots. As a result, The Dalles-Wahtonka High School changed its name to The Dalles High School, and its mascot from the Eagle-Indians to the Riverhawks, in April 2014. The 2014–2015 school year was the first year of The Dalles Riverhawks.

Main campus
The main campus has housed grades 9–12 since the 2009–2010 school year.
