Colonial dam removed on White Clay Creek

Abstract

In December 2014, researchers from the University of Delaware successfully removed a historic dam on White Clay Creek that had obstructed the spawning routes of local shad for over two centuries. The removal, a project spanning four years, was aimed at restoring fish passage and enhancing the creek's ecosystem. Jerry Kauffman, director of the Water Resources Agency, noted that prior to the removal, hickory shad were seen struggling against the dam.

While the majority of the dam was taken out, a portion will remain for historical study, allowing researchers to examine its construction details. Catherine Morrissey, a research associate, emphasized the lack of historical records regarding such dams in Delaware, making this a unique opportunity to learn about its design and materials.

The project was initiated in 2010 when a grant was applied for to study the feasibility of removing the dam, one of several on the White Clay. The project received financial support from various organizations, totaling $210,000. The removal is expected to create ideal spawning habitats for American shad, striped bass, and river herring, facilitating their movement upstream for the first time since the Revolutionary War.
