The Rio Vista Bass Derby & Festival is Rio Vista’s largest and most anticipated event of the year…

bringing together residents, visitors, and businesses for a lively celebration on the Sacramento River. Hosted by the Rio Vista Chamber of Commerce, this multi-day festival combines a premier fishing derby with live music, food and drink vendors, local artisans, family activities, and a classic small-town street fair atmosphere. Anglers compete for top catches while downtown fills with entertainment, community spirit, and riverfront energy. The Bass Festival not only showcases Rio Vista’s Delta heritage and outdoor lifestyle, but also plays a vital role in supporting local businesses and community programs through Chamber-led events and outreach.
