The Patuxent Wildlife Research Center.

The Patuxent River is a tributary of the Chesapeake Bay in the state of Maryland. There are three main river drainages for central Maryland: the Potomac River to the west passing through Washington D.C., the Patapsco River to the northeast passing through Baltimore, and the Patuxent River between the two. The 957 square miles (2,479 km2) Patuxent watershed had a rapidly growing population of 590,769 in 2000. It is the longest river to be located entirely within the state of Maryland. It is the largest river whose watershed lies completely in the state of Maryland.

Geography

The river source, 115 miles (185 km) from the Chesapeake, is in the hills of the Maryland Piedmont near the intersection of four counties - Howard, Frederick, Montgomery and Carroll, and only 0.6 mi (1.0 km) from Parr's Spring, the source of the south fork of the Patapsco River. Flowing in a generally southeastward direction, the Patuxent crosses the urbanized corridor between Baltimore and Washington, D.C., and opens up into a navigable tidal estuary near the colonial seaport of Queen Anne in Prince George's County, Maryland, just southeast of Bowie, Maryland, finding the Chesapeake Bay 52 miles (84 km) later. The fifty-two mile-long tidal estuary is never wider than 2.3 miles (3.7 km).

It marks the boundary between Montgomery, Prince George's, Charles and St. Mary's Counties on the west and Howard, Anne Arundel, and Calvert Counties on the east. The Chesapeake estuary's deepest point, 130 feet (40 m) below sea level, is in the lower Patuxent.

The Little Patuxent River, the Middle Patuxent River, and the Western Branch (in Prince Georges County) are the three largest tributaries. The Middle Patuxent flows into the Little Patuxent just upstream from the historic Savage Mill in Savage, Maryland. The Little Patuxent then joins the Patuxent just northeast of Bowie, Maryland. The Middle Patuxent flows through the middle of Howard County, while the Little Patuxent flows through northeast and southeast Howard County and western Anne Arundel County.

History

The Patuxent River was first named ("Pawtuxunt") on the detailed map resulting from the 1608 voyage upriver by Jamestown, Virginia settler John Smith.[1] Captain Smith got as far as the rough vicinity of the present-day Merkle Wildlife Sanctuary (Lyons Creek) area, 40 miles (60 km) from the Chesapeake on what is now the Anne Arundel - Calvert - Prince George's County tripoint.[2][3][4] This was most likely the second visit by Europeans to the Patuxent, as in June 1588 a small Spanish expedition under Vicente Gonzalez is believed to have anchored for the night in the Patuxent mouth by Kent Mountford.[5][6][7] By the mid and late 17th century respectively, colonists spread upriver to Mt. Calvert and Billingsley Point, two 18th century mansions 44 miles (71 km) upriver from the Chesapeake that are today part of Patuxent River Park. By the early 18th century, the Snowden iron ore furnace (also known as Patuxent Furnace) just southeast of Laurel, Maryland,[8][9] was shipping "pig iron" downriver from the current vicinity of the 1783 Montpelier Mansion, also part of Patuxent River Park.

In August 1814, Commodore Joshua Barney and his Chesapeake Bay Flotilla were trapped in the Patuxent by the British fleet under Admiral Sir George Cockburn. To keep them from British hands, Barney's men ignited the magazines of his ships in the four mile (6 km) stretch above Pig Point (44 miles (71 km) upriver from the Chesapeake and named after Snowden's "pig iron") when the British approached.[10] The British then launched their attack on Washington, D.C., from their warships in the Patuxent at Benedict. 22 miles (35 km) From there, the troops marched through, Nottingham, Upper Marlboro, Bladensburg and on to Washington.[11]

Economy and commerce

Tobacco farming dominated the Patuxent's economy for the two centuries following settlement, with about sixty percent of Maryland's tobacco coming from the Patuxent valley by the late 18th century.

Destruction of the plantations by the British and of the soil by centuries of tobacco farming brought the mid and lower Patuxent valley into a period of decline that would last until the 1930s, when there were fewer residents in the Patuxent's Calvert County than there were in the 1840s, and only a few hundred more than in the first Calvert County census in 1790.

The Patuxent was plied by regular steamship service, mostly from the Weems Line, from the 1820s to the 1920s, replacing the schooners and sailing packets that had for the previous centuries served the river's many landings and docks along the 53-mile (85 km) navigable reach.

The Washington Suburban Sanitary Commission constructed two dams on the main branch in the mid-20th century. Brighton Dam was constructed 96 miles (154 km) from the Chesapeake in 1943, impounding the waters of Triadelphia Reservoir; in 1952 the T. Howard Duckett Dam was constructed 14 miles (23 km) further downstream, near Laurel, thus creating Rocky Gorge Reservoir.[12] The land surrounding the two reservoirs is administered by the WSSC, creating a reserve of 4,400 acres (18 km2) forested accessible to the public for horseback riding, hunting, fishing, and picnicking in limited areas. The state of Maryland classifies the T. Howard Duckett Dam as "high hazard" because large releases of water flood areas of North Laurel.[13]

Including boating on the main river and the reservoirs, the impact that recreation in natural settings now has on the river's economy is obvious. The Patuxent Naval Air Station at the mouth of the river has continued to grow over past decades, providing along with tourism the main economic engine of the lower river valley which includes the popular boating center of Solomons, Maryland.

Environmental concerns

The Middle and Little Patuxent watersheds include nearly all of Columbia, Maryland, including its downtown urban Lake Kittamaqundi and Wilde Lake. Columbia is a large planned community in Howard County that opened in 1967. Columbia's major downtown roadway is called Little Patuxent Parkway, and Maryland Route 175 in East Columbia was known as the Patuxent Parkway until May 2006, when it was renamed for Columbia's founder, the late James Rouse, and his wife, Patty. It was the largely unchecked erosion from this late 1960s and 1970s building spree that contributed the bulk of the Patuxent River's highest and most damaging sediment, siltation, and pollution levels to date downstream. This in turn led to a nearly complete destruction of a once thriving seafood industry along the brackish portion of the river.

"The Patuxent River has known no greater friend, advocate and defender than Bernie Fowler."[14] Fowler, as an early-1970s Calvert County Commissioner, led the way in a lawsuit filed by downriver Charles, Calvert and St. Mary's counties against upriver counties. The lawsuit forced the state, the upriver counties, and the U.S. Environmental Protection Agency to enact pollution control measures. Between 1985 and 2005, the Patuxent saw a 26% decrease in nitrogen, a 46% decrease in phosphorus, and a 35% reduction in sediment, despite urban areas increasing to 31% of the watershed by 2002. Of the Chesapeake's major tributaries, the Patuxent is the only one having most of its harmful phosphorus and nitrogen nutrient overloads coming from urban runoff. The river's other two largest contributors, point sources (industrial, sewage, etc.) and the declining (24%) agricultural areas, contribute less of the nutrient load. Forested areas account for 43% of the watershed.[15][16]

In 2004 Fred Tutman became the first Riverkeeper for the Patuxent.[17] His role has been to protect and improve the quality of the river's water and watershed.[18]

Over the past 50 years, nationally-recognized land preservation efforts in this part of Maryland have saved tens of thousands of acres from the Baltimore-Washington bedroom community sprawl. The southern half of the U.S. Army's Fort Meade was added to the Patuxent Wildlife Research Center, which, at 12,300 acres (50 km2), is the second largest contiguous public park-refuge within 30 miles (50 km) of either Washington or Baltimore. It is located midway between these two cities. The contiguous public area of 8,575 acres (35 km2) centered on Jug Bay, 42 miles (68 km) upriver from the Chesapeake, form the fifth largest such Baltimore-DC preserve and largest tidewater one and consist of the Jug Bay Wetlands Sanctuary, the Merkle Wildlife Sanctuary, and the Jug Bay component of the Patuxent River Park. The 6,600-acre (27 km2) Patuxent River State Park in the uppermost part of the basin is the seventh largest.
