Atlantic Coast Wild Rice Tidal Marsh in Army                        Creek Watershed.

Army Creek suffers greatly from its industrial history and dense development.  Recent efforts in marsh restoration in tributaries at the south end have resulted in improvements.   Moreover, efforts made to restore tidal flow to the main part of Army Creek should result in improvements as well.

Watershed Area: 6,910 acres (2,796 hectares) including smaller tributaries to the south

Location:  North-central New Castle County on west side of Delaware River between the City of New Castle and Red Lion Creek watershed.

Flow Direction: Southeast towards the Delaware River and mainly tidal.

Characteristics:  Urban watershed with development and invasive exotic plant species.


Army Creek History


The north end of watershed is the scene of one of the oldest settlements in Delaware, New Castle.  New Castle was first settled by the Swedish, then the Dutch, then the British and finally the Americans once independence was declared.  Later in the 1800’s the area to the south of New Castle was developed as steel mills and electrical component plants. The lasting impacts of industry are seen today throughout the watershed.

Major Vegetation Communities/Land Covers


Cultivated lawn and impervious surface rank as the two largest land covers in the watershed and collectively cover more than half of the area.  Agricultural field is the third largest land cover. Northeastern Modified Successional Forest is the largest vegetation community and Northeastern Old Field rounds out the list at #5.
