Unusual Golden Sheen on the Nanticoke River Photo Credit: Tom Darby Written by Mike Pretl & Judith Stribling May 22 dawned as a normal though periodically rainy day for NWA’s Creekwatchers. Every other Monday from late March through early November – rain or shine -- our trained volunteers visit 36 sites on the river and its major tributaries, from Delaware down to Nanticoke. These citizen scientists collect water samples and partner labs analyze for total nitrogen, total phosphorus, chlorophyll a, and bacteria. Creekwatchers also measure dissolved oxygen, salinity, water temperature, water clarity, and total water depth directly. Lastly, Creekwatchers note and record on data sheets the temperature and weather conditions as well as any unusual phenomenon of the water or its surrounding habitat. That morning, our river waters displayed nothing abnormal, only an occasional, slight film of brownish algae, to be expected in the spring months.

McPherson (410) 238-4255 (410) 238-4210 Below Normal Rainfall and Warm Temperatures Lead to Record Low Water Levels in December Three months of above normal temperatures and four months of below normal rainfall have led to record low monthly streamflow and ground-water levels, according to hydrologists at the U.S. Geological Survey (USGS) in Baltimore, Maryland. Streamflow was below normal at 94 percent of the real-time USGS gaging stations and 83 percent of the USGS observation wells across Maryland and Delaware in December. Record low streamflow levels for December were set at Winters Run and Pocomoke River. Streamflow levels at Deer Creek and Winters Run in Harford County have frequently set new record daily lows for the last four months (see real-time graphs at http://md.water.usgs.gov/realtime/). Streamflow was also significantly below normal at Antietam Creek, Choptank River, Conococheague Creek, Nassawango Creek, Patapsco River, Gunpowder River, Patuxent River, Piscataway Creek, Monocacy River, and Potomac River in Maryland, and Christina River, St. Jones River, and White Clay Creek in Delaware. The monthly streamflow in the Potomac River near Washington, D.C. was 82 percent below normal in December and 54 percent below normal for 2001. Streamflow entering the Chesapeake Bay averaged 23.7 bgd (billion gallons per day), which is 54 percent below the long-term average for December.

  • Classifying Rivers - Three Stages of River Development
    Classifying Rivers - Three Stages of River Development River Characteristics - Sediment Transport - River Velocity - Terminology The illustrations below represent the 3 general classifications into which rivers are placed according to specific characteristics. These categories are: Youthful, Mature and Old Age. A Rejuvenated River, one with a gradient that is raised by the earth's movement, can be an old age river that returns to a Youthful State, and which repeats the cycle of stages once again. A brief overview of each stage of river development begins after the images. A list of pertinent vocabulary appears at the bottom of this document. You may wish to consult it so that you will be aware of terminology used in the descriptive text that follows. Characteristics found in the 3 Stages of River Development: L. Immoor 2006 Geoteach.com 1 Youthful River: Perhaps the most dynamic of all rivers is a Youthful River. Rafters seeking an exciting ride will surely gravitate towards a young river for their recreational thrills. Characteristically youthful rivers are found at higher elevations, in mountainous areas, where the slope of the land is steeper. Water that flows over such a landscape will flow very fast. Youthful rivers can be a tributary of a larger and older river, hundreds of miles away and, in fact, they may be close to the headwaters (the beginning) of that larger river. Upon observation of a Youthful River, here is what one might see: 1. The river flowing down a steep gradient (slope). 2. The channel is deeper than it is wide and V-shaped due to downcutting rather than lateral (side-to-side) erosion.

  • Monopoly and Monopsony Power in a Market for Mud
    Monopoly and Monopsony Power in a Market for Mud This article describes an unusual market I use in my intermediate microeconomics courses to illustrate characteristics of monopoly and monopsony power. For over sixty years the Lena Blackburne Rubbing Mud (LBRM) company has been the sole supplier of mud taken from a Delaware River tributary that is applied to all baseballs used by Major League Baseball (MLB) teams. The unique quality of the mud removes the shine and slickness of new baseballs. Students must explain why LBRM is or is not a monopoly and recognize the source of MLB’s monopsony power. Edward Scahill† †University of Scranton © 2020 Journal of Economics Teaching. All rights reserved. Scahill / Journal of Economics Teaching (2020) 1. Introduction A monopoly is an enterprise that is the only seller of a good or service… Before and during the period of the classical economics (roughly 1776–1850), most people believed that… [the] only monopolies that could persist… were those that got the government to exclude rivals… Even today, most important enduring monopolies or near monopolies in the United States rest on government policies…Monopolies that exist independent of government support are likely to be due to smallness of markets (the only druggist in town) or to rest on temporary leadership in innovation…(Stigler) Although most students in my intermediate economics courses understand the graphical analysis of monopoly and the impact of monopoly power on economic welfare, it is a challenge to find actual examples of monopoly power that engage their interest.1 Although dominant firms in many markets have some degree of monopoly power, the number of “pure” monopolies – sole providers of a good or service that have no close substitutes - are rare.
