Hadley Falls Dam
The Holyoke Dam, also referred to as the Hadley Falls Dam, or Hadley Falls Station is a granite dam built in tandem with the Holyoke Canal System at Hadley Falls on the Connecticut River, between Holyoke and South Hadley, Massachusetts. The water differential created by the dam produced mechanical hydropower for industrial uses in Holyoke, and later hydroelectric power. The current dam is the third structure to be built across the Great Falls at South Hadley. The dam, along with the Canal System and its Testing Flume, is recognized by the American Society of Mechanical Engineers as a Historic Mechanical Engineering Landmark for its use by Clemens Herschel in the development of the Venturi meter, the first means of measuring large-scale flows, and the McCormick-Holyoke Turbine by John B. McCormick, also known as the Hercules Turbine, which doubled the efficiency of turbines to more than 80% in its time. Background The river between Holyoke and South Hadley contained what was k ...

Freshet
The term ''freshet'' is most commonly used to describe a spring thaw resulting from snow and ice melt in rivers located in upper North America. A spring freshet can sometimes last several weeks on large river systems, resulting in significant inundation of flood plains as the snowpack melts in the river's watershed. Freshets can occur with differing strength and duration depending upon the depth of the snowpack and the local average rates of warming temperatures. Deeper snowpacks which melt quickly can result in more severe flooding. Late spring melts allow for faster flooding; this is because the relatively longer days and higher solar angle allow for average melting temperatures to be reached quickly, causing snow to melt rapidly. Snowpacks at higher altitudes and in mountainous areas remain cold and tend to melt over a longer period of time and thus do not contribute to major flooding. Serious flooding from southern freshets are more often related to rain storms of large tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holyoke Dam Prior To 1949-1951 Redevelopment Project
Holyoke is a city in Hampden County, Massachusetts, United States, that lies between the western bank of the Connecticut River and the Mount Tom Range. As of the 2020 census, the city had a population of 38,238. Located north of Springfield, Holyoke is part of the Springfield Metropolitan Area, one of the two distinct metropolitan areas in Massachusetts. Holyoke is among the early planned industrial cities in the United States. Built in tandem with the Holyoke Dam to utilize the water power of Hadley Falls, it is one of a handful of cities in New England built on the grid plan. During the late 19th century the city produced an estimated 80% of the writing paper used in the United States and was home to the largest paper mill architectural firm in the country, as well as the largest paper, silk, and alpaca wool mills in the world. Although a considerably smaller number of businesses in Holyoke work in the paper industry today, it is still commonly referred to as "The Pa ...

Canals In Massachusetts
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal.

Holyoke Gas & Electric
Holyoke Gas & Electric (HG&E), formally known as the City of Holyoke Gas & Electric Department (HGED), is a municipal electric, gas, and telecommunications utility primarily serving Holyoke and Southampton, Massachusetts, one of two in Massachusetts which provide all three services. Founded in 1902 with the purchase of gas and electric plants from the Holyoke Water Power Company, the municipal corporation launched its first fiber optics communications services in 1997. On December 14, 2001 the City of Holyoke purchased the majority of the remaining assets and operations of the Holyoke Water Power Company from Northeast Utilities and as a result the municipal utility assumed control of the Holyoke Dam and Canal System and an electric distribution system serving industrial electric customers in the flats neighborhood. The utility discontinued district steam service to conserve energy used in aging infrastructure in September 2010. Using hydroelectric power generation in tandem with ...

Cross Section Of The Third Holyoke Dam During Construction
A cross is a geometrical figure consisting of two intersecting lines or bars, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology. The cross has been widely recognized as a symbol of Christianity from an early period.''Christianity: an introduction'' by Alister E. McGrath 2006 pages 321-323 However, the use of the cross as a religious symbol predates Christianity; in the ancient times it was a pagan religious symbol throughout Europe and western Asia. The effigy of a man hanging on a cross was set up in the fields to protect the crops. It often appeared in conjunction with the female-genital circle or oval, to signify the sacred marriage, as in Egyptian amule ...

Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents .

Fairmount Water Works
The Fairmount Water Works in Philadelphia, Pennsylvania, was Philadelphia's second municipal waterworks. Designed in 1812 by Frederick Graff and built between 1812 and 1872, it operated until 1909, winning praise for its design and becoming a popular tourist attraction. It now houses a restaurant and an interpretive center that explains the waterworks' purpose and local watershed history. It was designated a National Historic Landmark in 1976 for its architecture and its engineering innovations. It was the nation's first water supply to use paddle wheels to move water. History Following a series of yellow fever epidemics in the late 18th century (which was at the time thought to be caused by unclean water or by rotting matter in the streets) city leaders appointed a "Watering Committee". The initial water system was designed by Benjamin Latrobe and accepted by the committee in 1799. His system utilized two steam engines (in series) to pump water from the Schuylkill River, into th ...

Second And Third Holyoke Dams, During Completion Of Latter, 1898
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units ( SI) is more precise:The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. Uses Analog clocks and watches often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
