Here is what I found online about the festival:
2018 Featured High School Choir: River Falls High School Concert Choir, Mrs. Carrie Loney, conductor & Ms. Sarah Joosten, conductor.
Every year, UWEC is proud to open up Clearwater Choral Festival Concert to one High School Choral Ensemble who continues to show excellence in their program and community. This year, we are excited to announce that the Featured Choral Ensemble is the River Falls High School Concert Choir. Under the direction of Mrs. Carrie Loney and Ms. Sarah Joosten, this choral ensemble and program continue to display the excellence of choral music.
