The dam behind Hearns Pond
Hearns Pond is held back by Hearns Pond Dam (also recorded as Hearn and Rawlin Mill Dam) , a concrete gravity structure, resisting the reservoir by its own weight alone , standing 14 ft high and running 580 ft along its crest , built across CLEAR BROOK in Sussex County , near SEAFORD . It was completed in 1912 and modified in 2002S;2006H;2006S;2017H;2017S , and is owned by DNREC DFW (a state owner) , to a design credited to DELDOT;DNREC;DUFFIELD ASSOC;MCCORMICK & TAYLOR;UNKNOWN.
Its recorded primary purpose is fish and wildlife pond — it is managed for habitat rather than yield . It also serves fish and wildlife pond;recreation.
It is founded on unlisted/unknown, with a metal core. Its spillway is ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. The spillway opening is 102 ft wide. Its outlet works use vertical lift2.
NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in. Its most recent condition assessment was satisfactory — no deficiencies recognised for expected loading. That assessment is dated 11/04/2024.
At its normal pool the reservoir covers about 24 acres. NID records a maximum storage of 1,434 acre-ft against a normal storage of 360 acre-ft. Its maximum discharge capacity is 3,977 cubic feet per second. It is regulated by DNREC.
