Anacostia River Trails

The Lower Potomac, Anacostia, Patuxent and Wicomico rivers are among the major waterways in the region, but hundreds of smaller streams, creeks and rivers abound providing numerous opportunities for recreational boating.

Anacostia River Watershed 176 square mile area of land encompasses most of the eastern half of the District of Columbia and large portions of Prince George’s County and Montgomery County in Maryland. The Anacostia has 13 major tributary creeks and streams - many with their own sub-watershed citizen advocacy groups; it starts near Bladensburg, MD, and runs for 8.5 miles before meeting the Potomac River at Hains Point in Washington, DC. 

Anacostia River Trails and Port Towns The word Anacostia is derived from the Nacotchtank Indian word anaquash; it means village trading center. In the 18th century the port at Bladensburg, Maryland, was 40 feet deep and served as a major center for colonial shipping fleets. Today, at Bladensburg Waterfront Park, site of the old port, the water often measures 3 feet deep or less. In the 18th century, the Anacostia River flowed through 2,500 acres of tidal wetlands. Today, less than 150 acres of wetland remain.

Wildlife The Anacostia River supports 188 species of birds and nearly 50 species of fish. Some of the animals you can see in and along the river include: bald eagles, beavers, white perch, ospreys, striped bass, cormorants, crayfish, herons, turtles, egrets, otters, herring, red fox, shad, kingfishers, and bullhead catfish.

Pollution and its Effect of Fish Species  Each year, Washington's antiquated combined sewer system dumps over 2 billion gallons of raw sewage and storm water directly into the river. Recent efforts have begun to reduce this overflow volume. According to the National Oceanic and Atmospheric Administration (NOAA), more than 20,000 tons of trash and debris enter the Anacostia's waters each year. Between 1989 and 2009, AWS volunteers collected and removed more than 850 tons of trash from the watershed. Experts estimate that approximately two-thirds (2⁄3) of brown bullhead catfish in the Anacostia River have tumors. The bullhead is an environmental indicator species for the Anacostia.

Predominantly rural with areas with dense population and suburban development closer to the Washington D.C. area. Steep cliffs can be found along the Chesapeake Bay shoreline and along areas of the Potomac River. Most of the streams, creeks and rivers experience tidal influences and have brackish water - a mix of fresh and salt water.

Charles County Water Trails along Mattawoman Creek, the lower Potomac River, Port Tobacco River and Nanjemoy Creek.

Point Lookout Water Trails Point Lookout State Park - the southernmost tip of St. Mary’s County where the Potomac River meets the Chesapeake Bay. The State Park offers a variety of paddling experiences that range from an hour or two to all-day excursions with overnight camping options on the Point Lookout peninsula.

Kingfisher Canoe Trail Prince Georges County, Anacostia River. Set in a very urban environment, this trail features some surprisingly natural areas as it passes by the Kenilworth Marsh and Aquatic Gardens and the National Arboretum. The trail begins at the Bladensburg public boat ramp and continues down the river to end at the Anacostia Park boat ramp.

Patuxent River Water Trail Anne Arundel, Prince Georges, Calvert, Charles, and St. Mary’s counties. 110 miles long. Many public parks and launching sites for recreational boating provide additional access for visitors to enjoy the river’s resources.

The Aberdeen South Dakota Commercial Historic District

Railroad Town Hub City and Main Street Commercial Development

Since its founding in 1881, Aberdeen has been the dominant regional commercial center for northeast South Dakota and the Aberdeen Commercial Historic District is the commercial core of this regional hub. Main Street is a homogeneous collection of brick buildings built between 1884 and 1983, with special emphasis on the 1908-29 period. The district conveys a strong feeling of architectural cohesiveness with design elements such as corbelling and geometric brick and concrete patterns as distinguishing features that reinforce the feeling of time and place.

General Characteristics the Aberdeen Commercial Historic District extends six full blocks on either side of the predominant commercial street in town, Main Street. All eighty-two buildings were built for commercial use, except for the recent brick Sherman Apartments and the 1899 Masonic Temple. As befits a railroad town, the linear district emanates from the source of Aberdeen's establishment, the Milwaukee, St. Paul & Pacific Railroad tracks, then continues south to Sixth Avenue - Highway 12.

The commercial development of Main Street has been continuous and the break in construction between 1938 and 1951 offers a distinct end to the period of significance, 1884 to 1938. The lengthy, four-decades-long period provides a significant continuum that illustrates the initial and unbroken economic vitality of Main Street. Within this fifty-four-year period of significance is a notable cluster of construction dates. Fully forty of the eighty-two buildings were built between 1908 and 1929, reflecting the boom years of Aberdeen's and South Dakota's commercial development.

Aberdeen was born of railroad construction and the related Dakota land boom of the 1880s. The selection of a site reflected the economic motives behind its creation. Representatives of the Milwaukee, St. Paul & Pacific Railroad were responsible for the town's founding and based their selection on the best chance for maximum economic return. They chose this site at the expense of the existing settlement of Columbia, favoring an intersection point with the North-Western Railroad, fully recognizing the economic dividends of a location at two intersecting rail lines.

The site was very flat and low. Sloughs and marshes greeted the actual surveyors in the fall of 1880. A town plan, named for the home town of Milwaukee Road president Alexander Mitchell, was filed on January 3, 1881, and the first lot buyers arrived that spring. The first train stopped at the station at the north end of Main Street on July 6, 1881, and from then on building after building was erected in rapid succession, according to contemporary reports by pioneer merchant T. Clarkson Gage. By that fall there were reportedly 250 residents.

Lots on Main Street sold for $125 for a 25-foot frontage, $150 for corner sites

The early buildings were small, hastily constructed wood frame stores with boom town fronts. With the highly advantageous position at the crossing of two rail lines and the resulting converging travelers, merchandise, and commodities, Aberdeen was immediately a locus for commercial enterprise in Brown County. The county grew from just 353 people in 1880 to 12,241 five years later, approximately 2,000 of them in Aberdeen.

By 1886 the eminence of Aberdeen was assured. Now three railroads served the community, giving the city the sobriquet, the Hub City. The U.S. Land Office opened an office there, and all manner of commercial enterprise served the growing hinterland. An 1889 city directory, for example, lists no less than eleven farm implement dealers, six banks and eight mortgage companies, seven dry goods stores, twenty hotels and boarding houses, six newspapers, and ten saloons

Depression and Rebuilding 1890-1929. The late 1880s also brought the end of the initial and speedy prosperity of the heady settlement era. Crop failures, then a nationwide financial depression in the 1890s ended the construction boom and stilled commercial development in Aberdeen. None of the extant buildings along Main Street apparently were built between 1893 and 1898. At the turn of the century came another cycle of plenty which continued unabated into the 1920s. Again, a land boom triggered speculation; rising crop prices brought a return to prosperity. Population mushroomed from 4,087 in 1900 to 10,150 a decade later, a 160 percent increase.

The further development of Main Street reflected the newfound abundance in Aberdeen, both in its expansion and in the quality of construction. Larger and more permanent and costly brick- veneered replacements dotted Main Street; every decade brought a spate of new buildings. Aberdonians gained the largest steel and concrete building in the state, except for the contemporary State Capitol. Built the following year, the McDiarmid & Slater Building occupied a pivotal corner site on the south end of block five, west side. Its distinctive tan brick with contrasting red- brown brick, corbelled cornice and lively geometric patterns exemplified Aberdeen commercial buildings from the early twentieth century.

. In 1926 the elaborate five- story Capitol Theater opened, its exotic Moorish and Gothic Revival motifs and immense neon sign a beacon on Saturday nights.

The Great Depression 1929-41. Following WWI and the related slide in farm product prices, agricultural areas such as northeast South Dakota suffered an economic decline. In 1929 the boom period ended in earnest nationally with the dramatic end to high stock market prices. Aberdeen was still the largest town on the Milwaukee Road between Minneapolis and Butte, Montana. With its large trading area extending from Roberts County west to the Missouri River and from the North Dakota border south to Redfield, it still could count on retail and wholesale sales, but at a diminished rate.  

Design Sources for many of the Main Street buildings are likely the product of presently anonymous practices--contractors, pattern books, local architects. During the rebuilding years of the early twentieth century, it is known that architects flocked to booming Aberdeen. Little has been identified about Aberdeen architects, but the 1910 city directory listed no less than seven architects.
