Wallowa Lake is a ribbon lake 1 mile (1.6 km) south of Joseph, Oregon, United States. Impounded by high moraines, it was formed by a series of Pleistocene glaciers. On the south end of the lake is a small community made up of vacation homes, lodging, restaurants, as well as other small businesses. Wallowa Lake has been used for recreation since at least 1880. It lies at the lowest elevation of all the lakes in the Eagle Cap Wilderness at 4,372 ft (1,333 m). The Wallowa Lake State Park is at the southern tip of the lake.
Geology and formation 
Wallowa Lake has been used in Geology text books as an example of a lake dammed by moraines. These moraines begin well below the water's surface and climb to over 900 ft (270 m) above the lake. Before the glacial till compounded enough to form the moraines that currently surround the lake, a large alluvial fan was present in the valley. This fan was created by the Wallowa River transporting debris into the valley. The sediment left by the river was pushed by a series of glaciers that advanced north into the valley. As they pushed the debris, they also dug deep into the earth. Though the number of glaciers that formed the moraines is debated, but the most accepted hypothesis is that eight or nine glaciers formed the walls that now dam the lake. The last glacier advanced into the valley about 17,000 years ago and is known as the Wallowa Glacier. Its moraines form much of the lake shore. Near Glacier Lake, high in the surrounding mountains, is evidence of several subsequent glacier advances. Occurring subsequent to the formation of Wallowa Lake, these did not reach the location of the lake. The oldest of these was 11,000–10,000 years before present.
Gold rush and battle with the Nez Perce 
The Wallowa Lake area was inhabited by the Wallowa band of the Nez Perce tribe prior to the exploration of the area and the formation of the U.S. State of Oregon. The lake and its surrounding area was guaranteed to the Nez Perce as part of the Treaty of 1855. This lasted until the discovery of gold in the area and the subsequent rush. Conflict with miners and other trespassers resulted in new treaty negotiations in 1863, in which American agents aimed to shrink the reservation, and exclude the Wallowa country from its boundaries. The Wallowa Nez Perce rejected the proposed treaty and refused to sign. However, chiefs from bands unaffected by the new boundaries, from the areas that remained within the reservation, did sign, placing the Wallowa band outside the reservation. By 1877, pressures from non-Indian settlers provoked violence, including the murder of Idahoans by some young Nez Perce warriors. Rather than submit to American notions of justice, Young Joseph led the Wallowas away from their homeland. After the war, the U.S. Government took the land and allowed it to be settled. This led to the formation of many of the nearby towns that still exist today.
The U.S. Government tried to force the non-treaty Nez Perce to relocate to the reduced Nez Perce Reservation. The non-treaty Nez Perce resisted by flight. This long set of skirmishes fought over a thousand miles and nearly five months between the U.S. Army and the non-treaty Nez Perce became known as the Nez Perce War. Finally, within 40 miles of the Canadian border, the Nez Perce were trapped and forced to surrender. On October 5, 1877, the day of the surrender, Chief Joseph gave the following speech:
I am tired of fighting. Our chiefs are killed. Looking Glass is dead. Toohulhulsote is dead. The old men are all dead. It is the young men who say yes or no. He who led the young men is dead. It is cold and we have no blankets. The little children are freezing to death. My people, some of them, have run away to the hills and have no blankets, no food. No one knows where they are, perhaps freezing to death. I want to have time to look for my children and see how many I can find. Maybe I shall find them among the dead. Hear me, my chiefs. I am tired. My heart is sick and sad. From where the sun now stands, I will fight no more, forever.
After the surrender, Chief Joseph and the Nez Perce were banished from the area. Today many monuments and dedications are set up at the lake and its surrounding cities in remembrance of the Nez Perce tribe and the battle that took place. In 1880 The town nearest to Wallowa Lake, Joseph, was named after Chief Joseph. The battle is remembered by historians as one of the last battles the U.S. forces had with Native Americans. It is also remembered and used as an example of the injustice the Native American people faced by the U.S. Government.
Formation of Joseph and Wallowa Lake tourism 
The first businesses near the lake were in the town of Joseph. In 1879 a man named Matthew Johnson who was the first post master for Joseph, ran the first store. Due to the needs of the crowds of gold miners who were flocking to the area, the store was a success and the town of Joseph began to grow. The area became so populated that Wallowa County was formed in 1887, which encompassed the lake and its surrounding cities.
Wallowa Lake gained popularity among gold miners and soon began attracting guests from other areas. Seeing an emerging tourism market, entrepreneurs began building businesses at the lake. Among those built was the Wonderland Inn, now known as the Wallowa Lake Lodge. The Wonderland Inn was developed in 1923 as an amusement park at the south end of the lake. The park contained a restaurant, store, bowling alley, dance hall, outdoor movie theater, horse drawn carousel and cabins for those wishing to stay overnight. An 18 passenger boat carried the guests who arrived in Joseph (which lies at the north end of the lake) down the entire four mile stretch of Wallowa Lake, finally arriving at the inn and amusement park.
The amusement park operated until 1940 when snow fall from an unusually harsh winter crushed most of the buildings and rendered the park inoperable. However, the inn survived the winter and still remains in operation, though renamed the Wallowa Lake Lodge. The area at the south end of the lake continued to be developed commercially. Several more stores, lodges, restaurants, and rental cabins were built in the following years, turning the south end of the lake into a tourist community.
Currently, the collection of businesses at the south end of Wallowa Lake are members of a non-profit tourism association. This association maintains a website, supports tourism in the area and works to solve issues across the lake community. For more information about the Wallowa Lake Tourism Committee see the website www.wallowalake.net. This website also provides information about available activities at the south end of Wallowa Lake.
There are 2,000 to 3,000 people residing at the south end of Wallowa Lake in summer with all businesses open. However, from October through March there are less than 40 year-round residences at the south end of the lake, and only a few lodging businesses remain open.
The lake's natural outlet to the north, closest to the town of Joseph, was the site of a private dam constructed in 1918 for irrigation, and raised to a 35-foot concrete gravity dam in 1929. No hydroelectric power is generated. It is owned and operated by a non-profit of local irrigation consumers, Associated Ditch Companies of Joseph.
In 1996 the United States Bureau of Reclamation and the Oregon Water Resources Department identified deficiencies in the safety of the aging "high hazard" structure. In 2006 state and federal money was appropriated for rehabilitation and a reconstruction which may allow a migrating fish passage, specifically for re-introduced coho and sockeye salmon.
Located near the lake is an aerial cable gondola lift. It runs from the bottom of the valley to the top of Mount Howard, which is measured at 8,000 ft (2,400 m). It was built in 1968 and opened to the public in 1970. From the tram car, the passenger can see spectacular views of Wallowa Lake as well as the surrounding mountains. In June 1992, a malfunction occurred in the operating system of the Tram and all passengers had to be evacuated by helicopter. There were no injuries and the incident serves as the only such problem that has occurred on the Tramway.
