Description
Scope/Content: Abstract: This 9-foot high dam, built of hand-cut stone, was the first blockage on Trindle Spring Run approximately 400 feet from its confluence with Conodoguinet Creek, a major tributary of the Susquehanna River near Harrisburg. The creek supports a reproducing population of rainbow trout and the dam was removed to improve fish habitat as well as to remove a liability to the new dam owner. The dam was over 150 years old and was originally built to power a grist mill, but it has not been used for this purpose for many decades. The removal required significant sediment management and disposal, due to some elevated levels of metals in the impounded sediments. Frequent turbidity measurements were taken throughout the course of the construction to ensure that sediment mobilization was minimized. The Cumberland Valley Trout Unlimited chapter and the Conodoguinet Watershed Association will assist with site monitoring for the newly-established riparian area and a newly-created stormwater treatment wetland for the adjacent shopping complex. The details in this grant report are subject to change.
