Brock, a privately owned dam located in Marinette, Wisconsin, stands as a crucial structure along the South Branch Pike river. Completed in 1971, this gravity dam serves primarily for recreational purposes, offering a storage capacity of 250 acre-feet and a normal storage level of 90 acre-feet. With a modest height of 16 feet and a spillway width of 21 feet, Brock's low hazard potential and fair condition assessment make it a reliable asset within the region.

Despite its relatively small size, Brock plays a vital role in managing water resources and supporting outdoor activities in the area. The dam's controlled spillway and maximum discharge capacity of 798 cubic feet per second ensure efficient water flow control during periods of high demand or emergency situations. Additionally, its location within the Chicago District underlines its importance for local water management and environmental preservation efforts.

While Brock may not be the largest or most imposing dam in Wisconsin, its presence on the South Branch Pike river serves as a reminder of the interconnectedness between water resources, climate resilience, and recreational opportunities. As water resource and climate enthusiasts, it is essential to recognize the significance of structures like Brock in maintaining the delicate balance between human needs and natural ecosystems in the region.
