States Day Celebrating 99 years of Community in Prosser with New and Old Traditions

Prosser’s oldest community event, “States Day” will be held on Monday, September 7th 2026, and offers something for the whole family. Kicking off the day is the Grand Parade which starts at 10:00am. With a long line of marching bands, floats, mounted entries, junior and senior organizations and more, the parade is usually the longest in Central Washington, with more than 100 entries each year. Those interested in participating as an entrant in the parade can contact the Chamber office for an entry form.

After the parade, family activities get underway at the city park. Stop on your way into the park to sign into your state of origin and don’t forget to purchase your States Day Commemorative buttons! Then grab food from our vendors before trying your luck at BINGO under the pavilion or enjoying the stage show, which shows off the talents of local groups.

Bring the family and enjoy a great day of fun, food, and entertainment at Prosser’s States Day Celebration, September 2, 2019.
