So far there Lactuca canadensis has been recorded only once in the Watershed, a plant Daniel Boyes found along Rito Seco Road, 12.5 km northeast of San Luis in Costilla Co (17 Nov 2019, iNaturalist observation #35843608). Despite its name, Canadian lettuce is native, present in all USA states east of the Great Plains and adventive in most states westward, including Colorado. BONAP shows it present in the Rio Grande drainage counties of Taos, Santa Fe, and Lincoln. Farther down stream, the species is unrecorded until Cameron Co of Texas, where the Rio Grande flows into the Gulf of Mexico.
