FIND THE BASS Are you a student, or an angler looking for information about bass and forage fish? In the past those data were only available by email request (s). Now, thanks to fishing license sales, maps of hot spots for bass are on the Public Access Map. New in 2019 will be an opportunity for the general public to download most of the data that we collect, including forage fish and water quality. Users only need to select a group of sites from a map, identify a time frame (if any), and a target species (if any). Look for this new opportunity later in the year from the Tidal Bass Program’s homepage. BLACK BASS ANNUAL REVIEW Volume 11 Page 3 2019 ELECTROFISHING 101 People have said electrofishing catches all the fish, messes up fishing, and worse, kills bass. But what is electrofishing and what does it really do 1. Electrofishers catch all the fish. Not true. Any to the fish? fishing gear captures only a portion of a population, though some gear is better than others. Single pass electrofishing captures only a portion of the population and how much depends on the type of species, abundance, habitat conditions, experience of the netters, and condition of the gear.

FAQs – Polluted Runoff and Fees POLLUTED RUNOFF IN BALTIMORE COUNTY Baltimore County contains the headwaters for many of the streams and tributaries feeding into the Patapsco River, one of the major rivers of the Chesapeake Bay. These tributaries include Bodkin Creek, Jones Falls, Gwynns Falls, Patapsco River Lower North Branch, Liberty Reservoir and South Branch Patapsco. Baltimore County is also home to the Gunpowder River, Middle River, and the Back River. Unfortunately, all of these streams and rivers are polluted by nitrogen, phosphorus and sediment and are considered “impaired” by the Maryland Department of the Environment, meaning the water quality is too low to support the water’s intended use. One major contributor to that pollution and impairment is polluted runoff. Polluted runoff contaminates our local rivers and streams and threatens local drinking water. Water running off of roofs, driveways, lawns and parking lots picks up trash, motor oil, grease, excess lawn fertilizers, pesticides, dog waste and other pollutants and washes them into the streams and rivers flowing through our communities. This pollution causes a multitude of problems, including toxic algae blooms, harmful bacteria, extensive dead zones, reduced dissolved oxygen, and unsightly trash clusters.

  • Patapsco River History
    Patapsco River History Welcome to NOAA's Patapsco River interpretive buoy, located at latitude 39 degrees 9.11 minutes north longitude 76 degrees 23.47 minutes west. It lies in the upper Chesapeake just east of the intersections of the Craig Hill and Brewerton ship channels entering in the Patapsco River in Baltimore's harbor from the south and north, respectively. The buoy sits in 20 feet of water surrounded by shallower lumps that would have been large oyster reefs when Captain John Smith and his crew arrived here, June 12, 1608, during their first exploratory voyage up the bay that summer. After leaving the Eastern Shore and crossing the bay to the Calvert Cliffs Smith and his crew sailed North in this direction. "We passed" he said "many shallow creeks" and that would be including today's West, Roads, South, Severn and Magothy Rivers, "but the first we found navigable for a ship we called Bolas. For the to clay in many places under the cliffs by the high water mark did grow up in red and white knots which made us thinke it Bole-Armoniack and Terra sigillata.", which were medicinal clays of the day. Over the next 2 days captain and crew continued up river to today's Elkridge placing a cross there, naming the spot Bland's Content and then coming back down stream to map the river with remarkable accuracy. They found no natives during this time, apparently this part of the Chesapeake western shore was a buffer zone between the Patuxent tribes to the south and the powerful, warlike Massawomeck and Susquehannock people to the north.

  • Garitee V. Mayor and City Council of Baltimore: a Gilded Age Debate on the Role and Limits of Local Government
    Garitee v. Mayor and City Council of Baltimore: A Gilded Age Debate on the Role and Limits of Local Government Kevin Attridge JD Candidate, May 2010 University of Maryland School of Law James Risk MA Candidate, History, May 2011 University of Maryland, Baltimore County Attridge & Risk - 1 I. Introduction In 1877, William L. Garitee brought suit against the city of Baltimore in what would become a pivotal case in public nuisance for the state of Maryland. Four years earlier, Daniel Constantine, a city contractor, began dumping in the Patapsco River between Colgate Creek and Sollers Point. The dredge came from the excavation of Baltimore’s Inner Harbor and improvements being made to the Jones Falls Canal. Constantine’s dumping directly affected William Garitee’s ability to conduct business from his wharf because the dumping reduced the depth of the river, making it impossible to access Garitee’s dock by ship. After making several attempts to get the city to stop dumping, Garitee was forced to file suit against the city. The Superior Court for Baltimore City decided the case in favor of the city, a decision Garitee appealed. The appeal was heard in the March term of 1880 by the Maryland Court of Appeals. Under Judge Richard Henry Alvey, the Court overturned the lower court’s decision and remanded the case to allow Garitee to proceed with his public nuisance claim and award damages. Politically, Garitee v. Mayor and City Council of Baltimore was part of the larger on- going debate on the role of government. During the Gilded Age, the Federal Government assumed a laissez-faire stance toward business, but the Progressive Era that immediately followed witnessed a restraint of business through the passage of the Sherman Antitrust Act and the trust-busting administration of President Theodore Roosevelt.

  • Appendix D—Mde Water Contact Advisory for Frog Mortar Creek
    APPENDIX D—MDE WATER CONTACT ADVISORY FOR FROG MORTAR CREEK 7980 • MARTIN STATE AIRPORT • DRAFT ENVIRONMENTAL ASSESSMENT - GROUNDWATER PLUME TREATMENT FACILITY FACTS ABOUT: Maryland Department of the Environment FROG MORTAR CREEK WATER CONTACT ADVISORY The Maryland Department of the Environment’s (MDE) Land Restoration Program, through its Controlled Hazardous Substance Enforcement Division, is overseeing Lockheed Martin Corporation’s (Lockheed Martin) environmental assessment and cleanup activities related to the release of chlorinated solvents and metals from areas around Martin State Airport in Middle River, Baltimore County, Maryland. In connection with this assessment, MDE is issuing a water contact advisory for the waters adjacent to the shoreline of the airport. What is the problem with Frog Mortar Creek near Martin State Airport? Under MDE’s oversight, Lockheed Martin has conducted environmental assessment activities at and around Martin State Airport. As part of those activities, Lockheed Martin collected surface water samples in March 2011 from the shoreline along Frog Mortar Creek. The chlorinated solvents Trichloroethene (TCE), cis -1,2 Dichloroethene (CIS-1,2) and Vinyl Chloride (VC) were identified in some surface water samples at levels that exceed MDE recommended lifetime risk screening levels. These risk estimates, which are based on lifetime exposures, are inherently conservative and do not represent any short-term health hazards. MDE requested that Lockheed Martin sample the surface water more frequently to determine the extent of the problem and whether seasonal trends exist. The data collected over the past year indicates that contaminant levels are highest during cooler weather, from fall through late spring and lower during the summer months, but the discharge of the three chlorinated solvents from the subsurface into the surface water is constantly changing.

  • Cross Keys Valve House
    The Commission for Historical and Architectural Preservation Landmark Designation Report April 9, 2013 Cross Keys Valve House 5106 Falls Road Baltimore, Maryland Commission for historical & architectural preservation KATHLEEN KOTARBA, Executive Director Charles L. Benton, Jr. Building 417 East Fayette Street Eighth Floor Baltimore, MD 21202-3416 410-396-4866 STEPHANIE RAWLINGS-BLAKE THOMAS J. STOSUR Mayor Director Significance Summary The Cross Keys Valve House was one of three stone Classical Revival gatehouses that serviced Baltimore City’s municipal water system along a conduit that ran from Lake Roland to the Mt. Royal Reservoir. Begun in 1858 and completed in 1862, this gravity- powered conduit system then located in Baltimore County provided the citizens of Baltimore with safe clean water. It was an engineering marvel when completed, and was the city’s first truly public utility. The waterworks was designed by James Slade, City Engineer for Boston and consulting engineer for the Baltimore Waterworks, and the waterworks was informed by the best practices of waterworks and engineers in other major American cities. The Cross Keys Valve House, completed in 1860, was originally called the “Harper Waste Weir”, which described a lower chamber in the valve house that collected debris from the water as it rushed through the conduit on its way to the city boundaries. The Valve House and the conduit over which it sits played a significant role in the city’s municipal water system, and represents a major engineering feat for the City of Baltimore. Property History This property is located just north of the modern gatehouse entrance of the Village of Cross Keys on the west side of Falls Road.
