S Line Dam, located in Churchill, Nevada, along the Carson River, serves primarily for irrigation purposes but also offers recreational opportunities. This earth dam stands at a height of 10 feet and stretches 6300 feet in length, with a storage capacity of 1200 acre-feet and a surface area of 150 acres. The dam features a controlled spillway and two slide gates for water release.

Managed by the Nevada Department of Water Resources, S Line Dam has a low hazard potential and was last inspected in September 2018, receiving a fair condition assessment. Despite its relatively low risk, the dam is considered to have a very high risk level due to its critical importance in water resource management in the region. The dam is under state jurisdiction and regulation, ensuring regular inspections and enforcement of safety measures to protect downstream communities and the environment. Water resource and climate enthusiasts can appreciate the vital role that S Line Dam plays in sustaining agricultural activities and providing recreational opportunities along the Carson River.
