Brief History of Cougar Hot Springs

Like other Oregon hot springs, Cougar Hot Springs was used by Native Americans for centuries. One of the first white settlers, who discovered and started using the hot springs in the 1860s, was Hiram Terwilliger. Almost 40 years later, in 1906, he filed a mineral-rights claim but it was denied by the Forest Service.

The official name of the hot springs is Terwilliger but the springs are mostly known as Cougar because of its proximity to Cougar Reservoir where it is drained through the Rider Creek.

The hot springs were an isolated remote destination until 1960 when the Cougar Dam and paved roads were built by the US Army Corps of Engineers.

After the 1960s, this destination became extremely popular. People began living in the area for weeks and months. From the 1970s to the 1990s, there were hundreds of people camping near the source of the springs. In the summer months, at the same time, it could be 1,000 people and more in this area.

The growth of crowds increased a rate of violence including loud night parties, littering, dealing drugs and alcohol, loitering and panhandling by hippy, and, finally, a murder that occurred in 1996.

In 1998 the Forest Service decided to charge a fee to use hot springs and prohibited camping near the hot springs. The fee system helped to clean and rebuild pools, the restrictions such as a night-closure policy and alcohol ban, made this place safer and more attractive for hot springs lovers.
