Fish Lake is a beautiful reservoir (a human-made lake) located in Jackson County, Oregon. It sits high up, about 4,639 feet (1,414 m) above sea level. You can find it about 35 miles (56 km) northeast of Medford.
Fish Lake started as a smaller, natural lake. But it was made much bigger by the 50-foot (15 m) tall Fish Lake Dam. This dam holds back the water from the north fork of Little Butte Creek. This creek is part of the larger Rogue River area.

How Fish Lake Was Formed
Fish Lake is surrounded by two cool volcanoes. To the north is Mount McLoughlin, and to the south is Brown Mountain.
About 2,000 years ago, lava flowed from Brown Mountain. This ancient lava now forms the southern shore of Fish Lake.
The Story of Fish Lake Dam
Fish Lake was once just a small natural lake. But in 1898, a company called the Fish Lake Water Company was created. Their goal was to help bring water to farms in the Rogue Valley.
They decided to make Fish Lake much larger. They also planned to enlarge a nearby lake called Fourmile Lake. This would allow them to store more water.
- Between 1902 and 1908, a temporary dam was built at Fish Lake.
- In 1906, the dam at Fourmile Lake was finished.
- By 1915, the two lakes were connected by the Cascade Canal. This canal brought water from Fourmile Lake over the Cascade Mountains to Fish Lake. This extra water helped fill Fish Lake even more.
- The temporary dam at Fish Lake was later replaced with a stronger, permanent earthfill dam.
- The dam was improved several times over the years. A new spillway (a channel for water to flow over) was added in 1955. Another spillway was built in 1996.
Thanks to all these changes, Fish Lake is now about three times bigger than it was naturally!
