Lake Horsethief Reservoir is a man-made reservoir located in Pierce County, Washington. The history of the reservoir dates back to the early 20th century when the area was primarily used for farming and agriculture. The construction of the reservoir was completed in the 1930s as part of a project to provide irrigation water to the surrounding farmlands.

The reservoir was created by damming the White River, which flows through the area. The dam was built with the intention of regulating water flow and providing a reliable source of water for irrigation purposes. The reservoir covers an area of approximately 100 acres and has a storage capacity of over 1,000 acre-feet.

In addition to its primary purpose of providing water for irrigation, Lake Horsethief Reservoir also serves as a recreational area for the local community. The reservoir is popular for fishing, boating, and swimming during the warmer months. There are also picnic areas and campgrounds surrounding the reservoir, making it a popular destination for outdoor enthusiasts.

Over the years, the reservoir has undergone several renovations and improvements to maintain its functionality and ensure the safety of its visitors. In the 1970s, a new spillway was constructed to enhance the dam’s capacity to handle increased water flow during periods of heavy rain or snowmelt. More recently, efforts have been made to preserve the reservoir’s natural habitat and ecosystem, including planting native vegetation and improving water quality.

Despite its relatively small size, Lake Horsethief Reservoir plays a significant role in the local community, providing both essential water resources for agriculture and a recreational space for residents and visitors to enjoy. The reservoir’s history is a testament to the ingenuity and resourcefulness of those who built it, as well as the ongoing efforts to preserve and protect this valuable natural asset for future generations.
