In 1980, it was estimated that there were fewer than 700 speakers of the language, including both the elderly and young. Hinton (1994:32) put a conservative estimate of the number of speakers at 150, and a liberal estimate at 400-500. As of 2009, 93 preschoolers were learning Quechan in the Quechan tribe's language preservation program, and the number of fluent speakers was estimated to be about 100. A Quechan dictionary was in progress.
Quechan speakers participate in the Yuman Family Language Summit, held annually since 2001.
A 2010 documentary, “Songs of the Colorado,” by filmmaker Daniel Golding features traditional songs in the Quechan language. Golding says, "The songs are all sung in the language, so if you're not learning and picking up the language, then you won't be able to understand the songs ... there are actually words telling stories..."
