In Times Past: Flood of 1936: Floods, Dams and Bridges

Eighty years ago this month a series of floods set records for high water in the Connecticut River Valley, throughout New England and a major portion of the eastern United States. This article deals with the impact of those floods. The winter of 1935-36 created the conditions that led to the floods that followed.

Across New England there was an above-average snowpack with high water content, heavy ice cover on rivers and deep penetration of frost. David Ludlum writes in The Vermont Weather Book: A great mass of frozen precipitation was stored on the hills and mountains awaiting spring conditions that would be its release to start downhill on the long journey to the sea. During the middle of March 1936 the Northeast experienced a series of storm systems.

Each moved from the Gulf of Mexico, eventually bringing heavy warm rainfall and rapidly rising temperatures to Vermont and New Hampshire. Ludlum reports that in the first major storm of March 11-12 over six inches of rain fell in northern New Hampshire and four inches fell in southern Vermont in a 24-hour period. During the second major storm, heavy rain fell over Northern New England on every day from March 16 to 22.

Wide areas of the region received between 10 inches and 30 inches of rainfall. The warm air and rainfall caused the ice-clogged waterways to breakup and flow downstream. The snowmelt added a tremendous volume of water to the ice-clogged rivers and streams.

Ice jams acted as dams and backed up water caused significant flooding. The United Opinion covered the local flooding in great detail. The headline for the March 20 th edition read Bradford is Practically Isolated from Outside World for Four Days.

Coincidentally, that edition included the first chapter of the romance novel Storm Music by Dornford Yates. The following description includes material from the newspaper along with accounts from other sources. During Wednesday night March 11 it rained.

Typical of the entire area, Fairlee village residents were kept awake by the rainfall and the men were kept busy turning water to keep it out of cellars. It rained all day on Thursday March 12, causing the Waits River and its tributaries to swell and sent out vast amounts of ice in monstrous ragged cakes. The railroad tracks were washed away at Pompanoosuc Station between Norwich and East Thetford, discontinuing all freight and mail trains.

A work train was stationed in Ely to provide support for the crews working to repair the wash outs on the roadbed all along the system. The Bradford golf course was completely inundated and by Saturday the water had, wrote one columnist, spread out into a beautiful lake many of us wish was a permanent feature for our little town. Sightseers on Sunday came to view the lake.

Some found Route 25 jammed with ice. Others traveled to East Barre whee another lake spread from the flood control dam to the base of Orange Heights. That dam, built following the Flood of 1927, protected Barre and Montpelier from the major damage they had previously experienced.On Monday the 16 th , torrents of rain fell and continued through the night.

By Tuesday night the roads south and north from Bradford village were closed to traffic, along with the road to Piermont. The water came up 5 feet during the night and the lake formed by the flooding Waits and Connecticut Rivers was dotted with ice flows and debris. The Bradford railroad station was surrounded by water and trains that had begun to get through were again stopped by submerged tracks.

The local grain facility lost over 60 tons of grain and cement. North Thetford village was flooded with much damage to homes and some residents had to be rescued by boat. Between Tuesday night and Wednesday, the Piermont, Orford and two Thetford bridges were closed as a result of the danger.

An ice jam at Newbury broke sending quantities of ice, water, logs and other debris against those structures. Loads of sand was used to prevent the bridges from floating away. The railroad bridge in Woodsville was weighted down with carloads of cinders.

One span of the East Thetford bridge was lost and the Orford-Fairlee covered bridge was damaged beyond repair. When the dams at 15-mile Falls and North Stratford, New Hampshire were either open or breached more water flooded into the already over-burdened Connecticut, flooding towns to the south. The middle sections of Jackman and Page dams in East Corinth went out, adding to the flood on the road to Bradford.

By Wednesday night, March 18 th , many communities were isolated with all roads closed. The rising water flooded the power station at the Bradford falls and electricity was cut off. Sections of Newbury, Piermont and Haverhill, especially Woodsville and areas along rivers, were also isolated and without electricity Thursday morning brought a cold leaden sky which over looked a desolate waste of water which had risen rapidly during the darkness.

At that point the level was two feet higher than that of the flood of 1927. The water lapped at the back of the buildings along the east side of Bradford s main street. About 3:30 Thursday afternoon, rain began to fall again.

By Friday morning, March 20, the rain had been replaced by the sun shining in a half hearted manner. It was on that day that the flooding reached its highest level, about five feet above the 1927 mark. Someone painted a line on the furnace building of the Bradford Academy to make note of that March 20 th high water level.

It still can be seen there and has never been surpassed. By Saturday the water began to recede and continued to do so over the next few days. The newspaper reported stories of rescues from the previous week of both individuals and livestock.

Stories of boats being used to get milk to dairies, voters to meetings and some students to the schools that remained open were also reported. Fairlee students who attended Orford High School were kept out of school until a temporary bridge could be built. During the flood, Norris s store in Woodville received supplies from Littleton via a trolley across the Wild Ammonossuc.

Lyme physician Dr. William Putnam opened an office at Thetford Academy and had a car on each side of the river while the East Thetford Bridge was being repaired. Much credit was given to the Central Vermont Public Service crew who came through in style, restoring electricity.

In several cases they worked from boats on wires suspended over floodwaters. Whatever damage and inconvenience suffered locally was small when compared to that experienced elsewhere across the northeastern half of the nation. From Virginia and Ohio through northern New England the great flood of 1936 inundated communities.

Rivers from the Mississippi to the Monongahela in the Midwest to the Kennebec and Saco in New England flooded. In many places high water broke records going back several centuries. In New Hampshire, the Merrimack flooded Manchester and Nashua and went on to flood the Massachusetts communities to the south.

Over 87 towns and cities in New Hampshire suffered flood damage. Along the entire length of the Connecticut River new flow records were established. As small rivers and streams added to the rainfall, the impact was magnified downstream.

At Bellows Falls 29 feet of water flooded over the top of the dam. North of the Vernon dam a six-mile ice jam broke submerging the top of the dam by nearly 11 feet and flooding the communities below. By March 19 th 50,000 residents of the lower Connecticut River valley were homeless.

Springfield, Massachusetts and Hartford, Connecticut were inundated in the worst flooding in history. Up to 200 lives were lost in New England and property damage was over $100 million. The floods significantly increased the demand for flood control and virtually assured the passage of some sort of national flood control legislation by the federal government.

Even as the Roosevelt administration was dispatching a force of 275,000 relief workers to the devastated areas of the Northeast, efforts were being made to push through a gigantic flood control bill. An editorial in The United Opinion in April, 1936 summarized the need: All New England now feels that something permanent must be done to prevent disastrous spring floods Southern New England now realizes that reservoirs nearer the headwaters of the rivers is their best protection since flood waters are no respectors (sic) of state lines It is an expensive program but more than worth its cost in the end. There had been federal flood control legislation and dam building projects before.

The Comerford Dam in North Monroe , built between 1928 and 1930 was, like many, primarily for hydroelectric power. Conversely, the East Barre dam was built by CCC workers in 1933-1935 as a flood control reservoir. The new proposal differed in significant ways.

By establishing a major commitment to protecting people and property from flood, it changed the role of the federal government. It expanded the role of dams to include reservoirs for flood control. The Army Corps of Engineers was also given greater responsibility for dam flood control construction and operation.

There had been earlier opposition to flood control projects from conservatives over this expanded role of the national government, the lack of revenue and the impact that dam construction might have on private property. That opposition virtually disappeared in the wake of the 1936 floods. On June 22, 1936 President Roosevelt signed the Flood Control Act of 1936 into law.

In later years, it would be followed by other legislation complimenting and expanding the federal government s role in flood control. Between 1941 and 1961 the Army Corps constructed seven flood control dam with the capacity to control a portion of the runoff from the upper Connecticut River watershed. The Union Village Dam and the North Hartland Dam are two of those.

The Corps also works with hydroelectric dam operators and private landowners to try to contain recurring floods. One provision of the 1936 legislation allowed states to enter into compacts involving flood control. Such agreements have been reached between Massachusetts and Connecticut and Vermont and New Hampshire to compensate the two northern states for the costs of protecting the two southern states.

The 1854 wooden covered bridge between Orford and Fairlee was damaged beyond repair and was dynamite. In June 1937, a new bridge was dedicated. Built for $209,000, it was named The Samuel Morey Memorial Bridge.

A new two-span bridge was built in 1937 between East Thetford and Lyme to replace the damaged 1896 bridge. Despite the changes in federal policy toward flood control, opposition to dam and reservoir construction continued. Republican George Aiken led the opposition to the enhanced Federal role in dam construction as a member of the Vermont legislature and as governor.

In 1938, Vermont U. S. Senator Warren Austin wrote in a private letter We are in a great fight over the New Deal flood control bill which would give the Federal Government power to seize more for dams and reservoirs, driving the inhabitants out, tearing up roads, etc.

We know we are licked, but we fight on. There was similar opposition when the new Wilder Dam was proposed in the 1940 s. For centuries there have been major floods on the Connecticut River.

Major ones between European settlement and 1936 include those in 1770, 1862, 1913 and 1927. Some of those caused greater damage than the 1936 flood. One example of this was the major destruction to Wells River village in 1927.

There have major floods since 1936, including 1952, 1960, 1973, 1996 and 2011. In some towns there was greater damage and higher flood levels than 1936, while other communities were spared. Much of the local area was spared the damage from Tropical Storm Irene that so devastated other parts of Vermont.

For centuries little children have chanted the nursery rhyme Rain, rain go away.

Come again some other day.

One thing is certain: for those of us who live in the Connecticut River watershed, that other day is sure to come and so will rain and, ever so often, floods.

AL-KO, la tecnologia al traino 0

AL-KO, la tecnologia al traino

Dallo stabilimento di Vandoies, in Val Pusteria, arriva la tecnica applicata al rimorchio leggero destinata a fornire efficienza e sicurezza in ogni situazione Per gli appassionati del turismo in camper e caravan, Il nome AL-KO ovviamente associato al grande numero di prodotti dedicati al veicolo ricreazionale, come telai, sospensioni, movimentatori, solo per citarne alcuni. AL-KO un azienda globale, con settori dedicati anche al giardinaggio, all hobbistica e alla grande climatizzazione; pi del il 50% del fatturato del Gruppo, per , rappresentato dalla tecnologia applicata ai veicoli. E nell ambito di quest ultima, la parte ricreazionale in senso stretto, solo una parte: AL-KO infatti, produce, ad esempio, anche i cavi Bowden destinati all automotive (per intenderci, i cavi che vanno ad azionare i cambi nelle automobili), le tiranteria varia compresa quelle dei freni a mano ammortizzatori e molle a gas.

C un settore, per , poco conosciuto almeno in Italia, che rappresenta una parte importantissima per il fatturato dell Azienda, ed quello dei rimorchi. Il rimorchio un oggetto che coinvolge sia il settore dello svago sia quello del lavoro, e proprio per questo il protagonista di un mercato molto ampio e variegato. Basti pensare che nel 2015 sono stati immatricolati, in Europa, circa un milione di rimorchi di vario tipo: cifra, questa, che se messa in confronto con quelle che normalmente sono ad appannaggio dei veicolo ricreazionale (camper e caravan) dimostra l importanza di un mercato che AL-KO presidia con particolare attenzione.

Uno dei protagonisti assoluti di questo settore in seno all organizzazione multinazionale AL-KO, si trova in Italia, ed lo stabilimento di Vandoies, nelle Val Pusteria, in provincia di Bolzano. In un dettagliato video , Alessandro Marco Butturini, Direttore Commerciale AL-KO Italia, ci porta per mano a conoscere i rimorchio e le sue componenti, in particolare quelle realizzate proprio nello stabilimento altoatesino. Costruito nel 1970, e successivamente ampliato e dotato delle pi moderne tecnologie, compresi i robot, questo complesso, che annovera 135 dipendenti, con un fatturato di circa 30 milioni di Euro, produce componenti essenziali per chiunque abbia bisogno di trainare e trasportare, per lavoro o per diletto.

L importanza che ha questo complesso per AL-KO sta in un dato molto significativo: a Vandoies, infatti, sono prodotti i freni a repulsione (il dispositivo meccanico con molla a gas che trasmette la frenatura della trattrice) per tutto il Gruppo Ma non solo: sempre da questo stabilimento escono gli assali dedicati proprio ai rimorchi leggeri e il gancio traino dotato di sistema di sicurezza AKS. Continuamente evoluto fin dalla sua prima apparizione, l AKS rappresenta un sistema di sicurezza fondamentale, come sanno benne i caravanisti di tutta Europa: un concetto abbastanza semplice (portare dei ferodi a stringere la sfera di traino, in modo da limitare le oscillazioni), ma al tempo stesso geniale e, soprattutto, molto efficace. Ma l attenzione per la sicurezza al traino di AL-KO non si ferma al sistema AKS, conosciuto perch universalmente applicato alla caravan, ma disponibile per tutti i tipi di rimorchi.

L ultima creazione AL-KO il AAA Premium Brake , acronimo che sta per Al-KO Automatica Adjustment , anche questo applicabile sia alle caravan sia ai rimorchi: si tratta di un sistema meccanico di autoregolazione dei freni a tamburo che recupera in moda totalmente automatico l usura del materiale d attrito garantendo sempre la massima forza frenante. Il sistema pi sofisticato dedicato alla sicurezza del traino , per , certamente l ATC : acronimo di AL-KO Trailer Control , e per ora disponibile solo per le caravan (ma allo studio la possibilit di essere adottato anche da altre tipologie di rimorchio), rappresenta, con la sua sofisticata gestione, il must assoluto in termini di sicurezza. l ATC collegato al sistema frenante della caravan e si attiva dopo che i suoi sensori rilevano ondeggiamenti ripetuti o un numero massimo di tre ampie sbandate, attivando i freni del rimorchi e permettendo cos al treno trattrice+ caravan di stabilizzarsi.

AL-KO, con la sua attivit dedicata tanto al mondo dello svago quanto a quello del lavoro, sempre all avanguardia tecnologica per quanto riguarda efficienza e sicurezza.

Ed inutile dire come faccia piacere che nonostante la grandezza di un Gruppo che ha sedi produttive e di sviluppo sparse praticamente in tutto il mondo, gran parte di questa tecnologia sia prodotta e si sviluppi proprio in Italia.

Cosmic radio bursts from beyond our galaxy excite astrophysicists … 0

Cosmic radio bursts from beyond our galaxy excite astrophysicists …

Vicky Kaspi is the recipient of this year’s Gerhard Herzberg Canada Gold Medal for Science and Engineering, the highest honour bestowed by the Natural Sciences and Engineering Research Council of Canada (NSERC). Photo courtesy of McGill University McGill University PhD student Paul Scholz had a eureka! moment last November as he sat at his computer, sifting through results from observations made by the Arecibo radio telescope in Puerto Rico.

The data showed several cosmic bursts with properties consistent with those of a fast radio burst (FRB) detected in 2012 mysterious split-second pulses that appeared to come from deep in outer space, beyond our galaxy. Ten bursts in all were found in the data and they have raised a deep space mystery that has baffled and excited scientists. The repeat signals were surprising and very exciting, said Scholz, who quickly called over his fellow researchers to look at his screen and share the news.

Astronomers have searched the sky in vain for repeat bursts until now. All previously detected FRBs appeared to be one-off events, thought to involve cataclysmic incidents which caused the type of spectacular explosion that could be seen across the universe and destroyed the source. Possible explanations included a star exploding in a supernova or a neutron star collapsing into a black hole.

In a paper published in Nature on Wednesday, the new finding indicates something different, or possibly points to a subclass of FRBs. It shows that at least some FRBs have other origins and likely come from an extremely powerful object that can produce multiple bursts in under a minute. Now that we have repeat bursts, it looks like they can survive the event, Scholz said in an interview.

We re thinking it looks like it might be a pulsar in another galaxy that is emitting pulses that are quite a bit brighter than any we ve seen in our galaxy. In that sense, it would be unprecedented. These extraterrestrial bursts likely occurred billions of years ago and certainly offer no proof of life in the universe they were much too distant, and much too strong, to have been caused by a civilization sending a signal, friendly or otherwise.

But the discovery does suggest the bursts emanated from something exotic, such as a rotating neutron star with unprecedented power. (A neutron star is the most dense thing in the universe after a black hole; it can be the size of a city with the mass of the sun packed into it and some rotate once per millisecond.) It was probably some extreme object like that, said Scholz, who is doing his PhD in astrophysics under the direction of Vicky Kaspi, the renowned McGill astrophysicist who heads the McGill Space Institute and just won the prestigious Killam Prize for academic-career achievement. The finding is the result of an international collaboration called PALFA for which Kaspi is principal investigator that includes researchers from Canada, the U.S., the Netherlands, the U.K. and Germany.

While it has shed some new light on FRBs, it also raises many questions. One of the team s next objectives is to determine where the radio bursts originated, possibly using a technique called interferometry. Finding the galaxy it s coming from would tell us about the environment it s coming from, said Scholz.

To date, only 17 FRBs have been found (the McGill team s 11 radio bursts count as one FRB source), so much is left to discover about this powerful, enigmatic phenomenon. Knowledge of FRBs may really start to advance when Canada s CHIME (Canadian Hydrogen Intensity Mapping Experiment) radio telescope becomes operational. It will be able to produce a map of cosmic structure over the largest volume of the universe ever observed.

It will definitely open a big window on FRBs, said Scholz.

And he and his team will eagerly be looking through it.
