The salinity ranges from 1.87% to 3.6%. [48] In 1573, Pedro Menndez de Mrquez, the governor of Spanish Florida, conducted further exploration of the Chesapeake. Watershed Science Is the Chesapeake Bay fresh or salty? 225232. The Chesapeake Bay drainage basin extends into six states, Institutional responses to pollution problems. Oyster and rockfish populations in the bay have improved, but blue crab populations have continued to decline. The U.S Geological Survey (USGS) reports that freshwater flow into the Chesapeake Bay during water year (WY) 2019 was the highest flow on record (fig. [116] Many organizations run continuous monitoring programs. The Chesapeake Bay is referenced in the hit musical. Restoration efforts that began in the 1990s have continued into the 21st century and show potential for growth of the native oyster population. [19] The largest rivers flowing directly into the Bay, in order of discharge,[20][21] are: For more information on Chesapeake Bay rivers, see the List of Chesapeake Bay rivers. Estuary in the U.S. states of Maryland and Virginia. Together, the salt being lost and the salt flowing in has historically kept the oceans' salinity levels in balance. Please leave comments that are respectful and constructive. 8. pp. The nature-based recreation of wildlife, boating, and ecotourism are dependent on enforcement of the Clean Water Act (CWA), which regulates pollutant discharges and supports related pollution control programs. So, the next time you're by the Baywhether at the beach, on a boat or in your neighborhoodtake a deep breath and enjoy the salty (or not-so-salty) smell of the air. [60], The Bay is famous for its rockfish, a regional name for striped bass. The Chesapeake Bay Program promotes oyster restoration projects to reduce the amount of nitrogen compounds entering the bay. The James is Virginia's largest tributary to the Chesapeake Bay. Open Year Round. but will also eat insects. [126] In 1949, after the Nazi's defeat in World War 2, the United States seized a German U-1105 built with sonar-evading rubber sheathing for study purposes. As a result the extent of such retrofit projects in the bay region has been limited. Average depth is 21 feet (6.4m), reaching a maximum of 174 feet (53m). The Chesapeake Bay is also home to a diverse flora, both land and aquatic. For example, see "Maryland's Two-Year Milestones", documents issued biennially outlining the state's projects and goals for pollution reduction. While it may simply be a breeze for you, the amount of salt you smell means a lot to the critters living below the water's surface. These facilities reduce erosion and keep sediment and other pollutants from entering tributaries and the bay. The Chesapeake Bay watershed has been heavily impacted by natural forces such as erosion, tides, and a history of hurricanes and other storms. Emporia State University. It is the seventh-oldest surviving English place-name in the United States, first applied as Chesepiook by explorers heading north from the Roanoke Colony into a Chesapeake tributary in 1585 or 1586. The Chesapeake Bay is an estuary, where freshwater and saltwater mix. Soil erosion and runoff of sediment into the bay, exacerbated by devegetation, construction and the prevalence of pavement in urban and suburban areas, also block vital sunlight. Three decades later, in 1607, Europeans again entered the Bay. A busy shipping channel (dredged by the U.S. Army Corps of Engineers since the 18) runs the length of the Bay, is an important transit route for large vessels entering or leaving the Port of Baltimore, and further north through the Chesapeake and Delaware Canal to the ports of Wilmington and Philadelphia on the Delaware River . They occupied an area that is now the Norfolk, Portsmouth, Chesapeake, and Virginia Beach areas. During the later half of the 19th century and the first half of the 20th century, the Bay was plied by passenger steamships and packet boat lines connecting the various cities on it, notably the Baltimore Steam Packet Company ("Old Bay Line"). At the point where the Susquehanna River flows into the Bay, the average depth is 30 feet (9m), although this soon diminishes to an average of 10 feet (3m) southeast of the city of Havre de Grace, Maryland, to about 35 feet (11m) just north of Annapolis. The ocean ecosystem itself extracts some of the salt from the water, with some creatures using them to create their shells or mineral deposits in the ocean. Physical geography Geology and formation Boundaries of the Chesapeake Bay impact crater. The Chesapeake Bay is an estuary to the North Atlantic, lying between the Delmarva Peninsula to the east and the North American mainland to the west. Seventy to ninety percent of all striped bass, known locally as rockfish, were spawned in the Bay. Salinity varies from 0.5ppt (parts per thousand) to 10ppt, and freshwater species can survive there. As an initial follow-up to the EPA report, the Chesapeake Bay Commission and EPA developed the Chesapeake Bay Agreement in 1983. Map of the Chesapeake Bay and salinity zones. A few days later in a "pincer attack", they also sailed up the Potomac River to attack Fort Washington below the National Capital and raided the nearby port town of Alexandria, Virginia. [79] The harvest's gross value decreased 88% from 1982 to 2007. Sea level rise has induced freshwater wetland loss via subsidence in the Blackwater River drainage of the Chesapeake Bay estuarine complex (Figure 1; Rogers and . Pfiesteria caused a small regional panic in the late 1990s when a series of large blooms started killing large numbers of fish while giving swimmers mysterious rashes; nutrient runoff from chicken farms was blamed for the growth. Water that was once clear for meters is now so turbid that a wader may lose sight of his feet while his knees are still dry. This article and it's comments have been very helpful and informative. The Chesapeake Bay BridgeTunnel, connecting Virginia's Eastern Shore with its mainland (at the metropolitan areas of Virginia Beach, Norfolk, Portsmouth, and Chesapeake), is approximately 20 miles (32km) long; it has trestle bridges as well as two stretches of two-mile-long (3.2km) tunnels that allow unimpeded shipping; the bridge is supported by four 5.25-acre (21,200m2) man-made islands. Water Resources Investigations Report 00-4218", "Endangered Species Around the Chesapeake", Sharks in the Chesapeake: More likely than thought, Whale in Chesapeake Provides Reminders About Nature, NOAA: Ship Speed Restrictions to Protect Endangered North Atlantic Right Whales, "Four rare Chesapeake Bay "oddities" to learn about this leap year", "Famous Manatee "Chessie" Sighted in Chesapeake Bay After Long Absence", "Manatee Traveler in Northeastern Waters Not Chessie", "Manatee spotted in tributary off Chesapeake Bay near Waldorf, Md", "Chesapeake Bay Program to release new data on underwater grasses in bay, rivers", "The Chesapeake Bay, Scenic and Unhealthy", "H.R. [citation needed]. I have witnessed plenty of sponge crabs at the mouth of the bay. [93] Scientists from the Virginia Institute of Marine Science at the College of William & Mary claim that experimental reefs created in 2004 now house 180 million native oysters, Crassostrea virginica, which is far fewer than the billions that once existed. [42] To produce enough food, labor was divided with men hunting while the women supervised the village's farming. The salt in the ocean comes from the land as rain reacts with rock. Unable to accurately carbon date the stone tool, archaeologists looked at similar styles of blade carving in order to gauge when it was made. Villages often lasted between 10 and 20 years before being abandoned due to local resources such as firewood running out or soil depleting. [46] Spanish explorer Lucas Vsquez de Aylln sent an expedition out from Hispaniola in 1525 that reached the mouths of the Chesapeake and Delaware Bays. [31][32] Endangered North Atlantic right whale[33] and fin, and minke and sei whales have also been sighted within and in the vicinity of the Bay. Salinity zones", "Factors Affecting Nutrient Trends in Major Rivers of the Chesapeake Bay Watershed. [citation needed], There were so-called "Oyster Wars" in the late 19th and early 20th centuries. Overharvesting, pollution, sedimentation and disease have turned much of the bay's bottom into a muddy wasteland. [72], The principal sources of nutrient pollution in the bay are surface runoff from farms, as well as runoff from urban and suburban areas. As a result, tourism has a notable impact on Maryland's economy. It runs from the mouth of the Rappahannock River to the mouth of the Bay. The bay forms part of the Atlantic Intracoastal Waterway. As a reminder, all areas of the Chesapeake Bay will be closed to any targeting of striped bass from July 16 through July 31. Until the mid-h century, oyster harvesting rivaled the crab industry among Chesapeake watermen, a dwindling breed whose skipjacks and other workboats were supplanted by recreational craft in the latter part of the century. [78] It has been estimated that in pre-colonial times, oysters could filter the entirety of the bay in about 3.3 days; by 1988 this time had increased to 325 days. 16 inches. Common submerged aquatic vegetation includes eelgrass and widgeon grass. It's so damned beautiful.[50]. [61], Other popular recreational fisheries in the Chesapeake Bay include shad,[62] cobia, croaker, and redfish, winter flounder, and summer flounder. Farms in Lancaster County, Pennsylvania generate large quantities of manure that washes into tributaries of the bay. Chloride and sodium, two of the most common ions in the seawater, are "salty." In addition to the difference in salinity from north to south, the water on the Bays Eastern Shore tends to be saltier than water on the western side, due to two factors: Most of the water in the Bay, including in the middle portion of the Bay and its tidal rivers, is brackish. Salinity is different from region to region and sometimes even from rainy season to dry season. I planned to spend my days boating, eating as many Chesapeake Bay blue crabs as possible and making a little study of Eastern Shore locals. Various local K-12 schools in the Maryland and Virginia region often have programs that cultivate native bay grasses and plant them in the Bay. Chesapeake Bay Facts Width and Depth. It begins in the mountains at the confluence of the Cowpasture and Jackson Rivers in Botetourt County and ends at the Chesapeake Bay in Hampton Roads. [78] The bay's oyster industry has also suffered from two diseases: MSX and Dermo. [83], In 1987 the parties agreed to set a goal of reducing the amount of nutrients that enter the bay by 40 percent by 2000. [14], Much of the Bay is shallow. . The otherhalf drains into the Bay from an enormous 64,000-square-mile drainage basin orwatershed. [34][35][36] The same manatee has been spotted as far north as Rhode Island, and was the first manatee known to travel so far north. [6] Nutrient pollution and urban runoff have been identified as major components of impaired water quality in the bay stressing ecosystems and compounding the decline of shellfish due to overharvesting. Captain John Smith of England explored and mapped the Bay between 1607 and 1609, resulting in the publication in 1612 back in the British Isles of "A Map of Virginia". Very helpful. [101] A land developer may install stormwater management facilities such as infiltration basins or constructed wetlands during the construction of housing or commercial buildings. From everything I have learned about crabs in the bay, crabs grow better in less salty water. December 1, 2016. Daily4. [121], Water makes up 25% of the State of Maryland and there are over 550 submerged archaeological sites that have been located across the Chesapeake Bay and its surrounding watersheds. The Chesapeake Bay is . Short of tasting the water in the harbor, this provided me with EXACTLY what I was looking for! Warmer waters can hold less dissolved oxygen. Wang, D-P. and A.J. Written by Sherri Dalphonse | Published on September 2, 2020 Tweet Share Gorgeous gorge: Great Falls Photograph by Lauren Bulbin Here are some examples of Chesapeake Bay aquatic plants. It is highly invasive, and has the potential to flourish in the low-salinity tidal waters of the Chesapeake Bay. "[50] The Captain John Smith Chesapeake National Historic Trail, the first designated "all-water" National Historic Trail in the US, was established in 2006 by the National Park Service. For example, oysters require salty waters and they cant move if conditions change. Unfortunately, following the publicity of these sunken ships, many divers have taken it upon themselves to explore the wreckage for 'treasure'.[128]. If you are fishing upstream of the location listed, nontidal fishing regulations apply. The striped bass ( Morone saxatilis ), also called the Atlantic striped bass, striper, linesider, rock, or rockfish, is an anadromous perciform fish of the family Moronidae found primarily along the Atlantic coast of North America. The commission consults with the state legislatures and executive agencies, as well as Congress, about environmental, economic and social issues related to the bay.[84]. [108], The health of the Chesapeake Bay improved in 2015, marking three years of gains over a four-year period, according to a 2016 report by the University of Maryland Center for Environmental Science (UMCES). After months of harassment by Barney, the British landed on the west side of the Patuxent at Benedict, Maryland, the Chesapeake Flotilla was scuttled, and the British trekked overland to rout the U.S. Army at Bladensburg and burn the U.S. Capitol in August 1814. Total shoreline including tributaries is 11,684 miles (18,804km), circumnavigating a surface area of 4,479 square miles (11,601km2). One study noted sea level fluctuations at periods of 5 days, driven by sea level changes at the Bay's mouth on the Atlantic coast and local lateral winds, and 2.5 days, caused by resonant oscillations driven by local longitudinal winds,[55] while another study later found that the geometry of the Bay permits for a resonant period of 1.46 days.[56]. [98], EPA's 2010 TMDL document requires all states in the bay watershed region to develop detailed implementation plans for pollutant reduction. For example, in the smaller rivers that empty into the Chesapeake Bay (characterized by extensive tidal freshwater wetlands in contrast to . The Atlantic sturgeon has five rows of bony plates known as scutes that run . Scientists' Cliffs is a beach community in Calvert County named for the desire to create a retreat for scientists when the community was founded in 1935. [95] EPA, which had been working with the states on various components of the TMDL since the 1980s (e.g. Saltwater anglers who are not required to hold Maryland a Bay & Coastal Sport Fishing license and want to fish the Chesapeake Bay and tidal Potomac River must obtain a free Maryland Saltwater Angler Registration. )[17], The climate of the area surrounding the Bay is primarily humid subtropical, with hot, very humid summers and cold to mild winters. Virginia Saltwater Recreational Fishing Licenses: The fishing licenses listed below are required for recreational, non-commercial use of a rod-and-reel (hook and line), handline, spear or gig, cast net, or up to two eel pots in Virginia tidal saltwater areas including the Atlantic Ocean out to the three mile limit.
