Christina, also known as Christina Lake, is a privately owned dam located in Fremont, Wyoming, specifically in the city of Lander. Built in 1942 by designer C.J. Francis, this earth dam stands at a height of 20 feet and serves primarily for irrigation purposes, with a storage capacity of 5350 acre-feet. The dam is situated on the Little Popo Agie River, with a drainage area of 5.2 square miles and a maximum discharge of 10700 cubic feet per second.

With a spillway width of 50 feet and an uncontrolled spillway type, Christina presents a significant hazard potential, leading to a moderate risk assessment rating. The dam's structural height reaches 22 feet and spans a length of 505 feet, holding a surface area of 350 acres. Despite being privately owned, the state of Wyoming regulates and inspects Christina, ensuring that it meets safety standards and enforcement measures. The last inspection was conducted in July 2021, with a regular inspection frequency of 5 years to monitor its condition and potential risks. For water resource and climate enthusiasts, Christina serves as a vital infrastructure for irrigation in the region, showcasing the intersection of human engineering with environmental sustainability.
