Bloom is a privately owned dam located in Tripp, South Dakota, along the Old Lodge Creek Trib. Built in 1934 by the WPA, this earth dam stands at a height of 16 feet and has a length of 520 feet, providing a storage capacity of 240 acre-feet. With a low hazard potential and a moderate risk assessment rating, Bloom is a vital structure in the region for water resource management.

Managed by the South Dakota Department of Environment and Natural Resources (DENR), Bloom is regulated, permitted, inspected, and enforced by the state. Although the dam is not currently rated for its condition, it is considered to meet operational guidelines. The spillway, with a width of 70 feet, is uncontrolled, allowing for a maximum discharge of 6,830 cubic feet per second.

For water resource and climate enthusiasts, Bloom serves as a fascinating example of early 20th-century infrastructure designed to manage water flow in the area. Its historical significance, combined with its functionality in today's water management practices, highlights the importance of maintaining and monitoring such structures for the sustainable use of water resources in the region.
