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.
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 2014âÂÂ2015 school year was the first year of The Dalles Riverhawks.
The main campus has housed grades 9âÂÂ12 since the 2009âÂÂ2010 school year.
The Dalles High School currently uses a Trimester system as opposed to the standard semester System. The Dalles hosts a number of required common academics courses as well as offering College Now courses with an agreement with Columbia Gorge Community College to earn college credit early.
