Moslander is a privately owned irrigation dam located in Piedmont, Wyoming, along Big Muddy Creek in Summit, Utah. Built in 1882, this Earth dam stands at a structural height of 14 feet and has a hydraulic height of 10 feet. With a storage capacity of 85 acre-feet, Moslander serves the primary purpose of irrigation in the region. Despite its age, the dam has a low hazard potential and has not been rated for its condition.

Managed by the Utah Division of Water Rights, Moslander is subject to state regulation, permitting, inspection, and enforcement. The last inspection of the dam took place in August 2004, with an inspection frequency of every five years. While there are no associated structures or spillways, Moslander is equipped to handle the normal storage of 75 acre-feet. Its location in a remote area and its historical significance make it an intriguing site for water resource and climate enthusiasts to explore.

With its rich history dating back to the late 19th century, Moslander remains a vital part of the irrigation infrastructure in Utah. Its construction marked a significant development in water management in the region, and its continued operation underscores the importance of maintaining and inspecting aging dams for safety and efficiency. As climate change poses challenges to water resources, Moslander stands as a reminder of the critical role that dams play in supporting agriculture and water supply in the arid western landscapes.
