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.

==Geography==
The river source, {{convert|115|mi|km|0}} from the Chesapeake, is in the hills of the Maryland [[Piedmont (United States)|Piedmont]] near the intersection of four counties – [[Howard County, Maryland|Howard]], [[Frederick County, Maryland|Frederick]], [[Montgomery County, Maryland|Montgomery]] and [[Carroll County, Maryland|Carroll]], and only {{convert|0.6|mi}} 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, Maryland|Baltimore]] and [[Washington, D.C.]], and opens up into a navigable tidal [[estuary]] near the colonial seaport of [[Queen Anne, Prince George's County, Maryland|Queen Anne]] in [[Prince George's County, Maryland]], just southeast of [[Bowie, Maryland|Bowie]],. finding theThe Chesapeakeriver Bayis bounded by significant marsh areas for {{convert|5222|mi|km|0}} later.from the The[[Waysons fifty-twoCorner, mileMaryland|Waysons Corner]] area to the Hunting Creek confluence. The {{convert|52|mi|km|0}}-long tidal [[estuary]] is never wider than {{convert|2.3|mi|km|1}}.
 
It marks the boundary between [[Montgomery County, Maryland|Montgomery]], [[Prince George's County, Maryland|Prince George's]], [[Charles County, Maryland|Charles]] and [[Saint Mary's County, Maryland|St. Mary's]] counties on the west and [[Howard County, Maryland|Howard]], [[Anne Arundel County, Maryland|Anne Arundel]], and [[Calvert County, Maryland|Calvert]] counties on the east. The Chesapeake estuary's deepest point, {{convert|130|ft|m|0}} below sea level, is in the lower Patuxent.
 
The two largest cities in the watershed are [[Bowie, Maryland|Bowie]] and [[Laurel, Maryland]]. There is a percentage of [[agricultural]] activity in the region as well. The mid and lower banks of the river have swamp and marshland [[ecosystems]]. Many of those ecosystems are protected by some form of parkland, on the state and local levels. The most notable of which include [[Jug Bay Wetlands Sanctuary]], [[Merkle Wildlife Sanctuary and Visitor's Center|Merkle Wetlands Sanctuary]] in the [[Merkle Wildlife Sanctuary and Visitor's Center|Edgar A. Merkle Wildlife Refuge]],<ref>Meyer, Eugene L., ''[https://www.washingtonpost.com/archive/local/1984/08/18/the-legacy-of-edgar-merkle-canada-geese-on-the-patuxent/5d0683b9-3da9-41a6-aa57-6a15b4b7010a/ The Legacy of Edgar Merkle: Canada Geese on the Patuxent], The Washington Post, August 18, 1984 </ref><ref>https://web.archive.org/web/20100815073135/http://www.dnr.state.md.us/publiclands/southern/merkle.asp Merkle Wildlife Refuge web site</ref> and [[Patuxent River Park]], along with many more. Farther north, there is the 20 square mile Patuxent Research Refuge, which helps to protect Patuxent River wildlife.

{{anchor|Western Branch}}The '''Little Patuxent River''', the '''Middle Patuxent River''', and the '''Western Branch''' are the three largest tributaries. The Middle Patuxent flows into the Little Patuxent just upstream from the historic [[Savage Mill]] in [[Savage, Maryland|Savage]]. The Little Patuxent then joins the Patuxent just southwest of [[Crofton, Maryland|Crofton]]. The Middle Patuxent flows {{convert|24|mi}} through the middle of Howard County, while the Little Patuxent flows {{convert|38|mi}} through northeast and southeast Howard County and western Anne Arundel County.<ref name=NHD>U.S. Geological Survey.

The word ''Patuxent'' is derived from the [[Algonquin language]] used by the indigenous people living in the area prior to the arrival of the European settlers. Its meaning is debated.

==Economy and commerce==
[[Tobacco]] farming dominated the Patuxent's economy for the two centuries following white settlement, with about sixty percent of Maryland's tobacco coming from the Patuxent valley by the late 18theighteenth 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.
Line 190 ⟶ 191:
The Patuxent was plied by regular [[steamship]] service, mostly from the Weems Line, from the 1820s to the 1920s, replacing the [[schooner]]s and sailing [[Packet (sea transport)|packets]] that had for the previous centuries served the river's many landings and docks along the {{convert|52|mi|km|0|adj=on}} tidal reach.
 
The [[Washington Suburban Sanitary Commission]] constructed two dams on the main branch in the mid-20thtwentieth century. [[Brighton Dam]] was constructed {{convert|96|mi|km|0}} from the Chesapeake in 1943, impounding the waters of [[Triadelphia Reservoir]]; in 1952 the [[T. Howard Duckett Dam]] was constructed {{convert|14|mi|km|0}} furtherfarther downstream, near Laurel, thus creating [[Rocky Gorge Reservoir]].<ref>Washington Suburban Sanitary Commission. Laurel, MDMaryland (2007). [http://www.wsscwater.com/about/history.cfm "The WSSC-- A Thumbnail History."], Accessed 2010-02-15.</ref> The land surrounding the two reservoirs is administered by the WSSC, creating a forested reserve of {{convert|4400|acre|km2|0}} accessible to the public for horseback riding, hunting, fishing, and picnicking in limited areas.

V.2, No. 6, October 2006.</ref>
 
With public recreational land on one or both shores of 74 of the river's 115 miles including the reservoir land, the impact that recreation in natural settings now has on the river's economy is obvious. The [[NAS Patuxent River|Patuxent Naval Air Station]] at the mouth of the river has continued to grow overduring past decades, providing along with tourism, providing another main economic engine in the lower river valley whichthat includes the popular boating center of [[Solomons, Maryland|Solomons]].
 
The Patuxent River is the sole known source for Maryland's State Gemstone, a form of agate called [[Patuxent River stone]].<ref>{{cite web | url=https://www.ereferencedesk.com/resources/state-gemstone/maryland.html | title=Maryland State Gemstone: Patuxent River Stone (Agate) }}</ref>
 
==Environmental concerns==
According to EcoHealth Report Cards, the Patuxent River has a below average health rating, scoring a 38%, compared to the Chesapeake's over all health rating of 54%, as of 2016. However, the river does have higher ratings in dissolved oxygen, and likely, will soon have higher ratings in phosphorus.<ref>{{Cite web|url=https://ecoreportcard.org/report-cards/chesapeake-bay/health/|title=Health {{!}} EcoHealth Report Cards|website=EcoReportCard|language=en|access-date=2018-03-15}}</ref>
 
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 [[water pollution|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.

Quote attributed to Congressman [[Steny Hoyer]].</ref> Fowler, as an early-1970s Calvert County Commissionercommissioner, 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 [[urbanization|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 source]]s ([[industrial wastewater treatment|industrial]], [[sewage]], etc.) and the declining (24%) [[agriculture|agricultural]] areas, contribute less of the nutrient load.
