The course of the Little Popo Agie River

The Little Popo Agie River runs through unincorporated portions of Fremont County Wyoming. The river's headwaters are at Christina Lake in the Wind River Range, and it flows a total of 58 miles (93 km) until its end near Hudson, Wyoming.

The river's head is about 10,000 feet (3,050 m) above sea level, and its end is at around 5,000 feet (1,520 m) above sea level.

Since at least the early 20th Century, some sections of the river have had problems with pollution thought to have come from industrial operations at nearby oil extraction sites. Around 1907, sufficient oil waste was reportedly being dumped into the Little Popo Agie Rver. This led to several lawsuits being filed for damages by locals using the river's water for irrigation against oil companies operating in the area. Pollution from oil waste was linked to decreased fish habitat on the river in the 1950s.
