Big Park Watershed Site C-1 is a crucial water resource located in Crawford, Iowa, along the TR-Boyer River. Owned by the local government, this site was designed by the USDA NRCS and completed in 1962 for the primary purposes of fire protection, stock, and small fish pond management, as well as flood risk reduction. The earth dam stands at 43 feet high and spans 256 feet in length, with a storage capacity of 55 acre-feet and a surface area of 2 acres.

Despite being classified with a low hazard potential, the condition of the dam is currently not rated, and the last inspection took place in November 1963. The risk assessment for the site is moderate, indicating a potential for issues that may need to be addressed in the future. The dam is regulated by the state of Iowa and falls under the jurisdiction of the Iowa DNR, with permitting, inspection, and enforcement processes all in place to ensure its safety and compliance with regulations.

With its strategic location and importance for various water management purposes, Big Park Watershed Site C-1 serves as a significant asset in the region's efforts to safeguard against flood risks, provide essential water resources, and support environmental conservation. As water resource and climate enthusiasts, understanding and monitoring the condition and management of such sites is vital for ensuring the sustainability and resilience of our water systems in the face of changing climate conditions.
