Lough Allen to Sligo (OSI 25″ ~1900)
In looking at the map of Ireland, it has appeared to me that it may be found of advantage to prevent the waters of Lough Allen from flowing into the Shannon, and to cut a channel in a north-westerly direction, along which they may run into Sligo Bay. By this disposition of the waters of Lough Allen, not only will the channel of the Shannon be relieved from the superabundant water which now flows along during the rainy season, but they will act very beneficially in scouring out the harbour of Sligo. The Shannon might likewise be made available to the supply of power to several valuable mills to be erected on its course.

It says here
Minister Naughten also announced that Meelick Weir just north of Lough Derg will be removed.
I can’t find anything about this on Mr Naughten’s department’s website and Boxer Moran’s speech doesn’t mention it.
Were it true, getting a boat upstream (or indeed down) past Shannon Grove would become even more exciting. Perhaps it’s time to restore Hamilton’s Lock.
Of course if the weir is removed there will be no point in restoring the walkway.

Lewis Davis says:
Empirically, I find a robust negative correlation between rainfall variation, a measure of exogenous agricultural risk, and a measure of individual responsibility. Using rainfall variation as an instrument, I find that individual responsibility has a large positive effect on economic development.

To the Editor of the Athlone Times 24/8/1889
I understand that the Athlone Board of Guardians passed a resolution at a recent meeting in favour of the drainage of the Shannon. May I ask, is it the object of these enlightened gentlemen to destroy the navigation of 240 miles passing through our country, which no law can ever restore; or can it be possible they so far despair of the future traffic of the country under the management of their Parliament, in College Green, as to feel warranted in doing away with such a natural and beautiful highway for trade.
I happen, myself, to be in a position to judge the agricultural part of the question, and after the experience of 25 years of the lands which are subject to the Shannon flooding, I have no hesitation in saying that the meadows are greatly improved, and I may mention that in no way could these lands be more profitably farmed than by meadowing.
To the Athlone people, it seems to me a matter of the greatest importance, or do they realise that their beautiful river is about to be turned into a mere cesspool, their traffic to be left at the mercy of the railway companies, and their boating excursions on their fine lake to be made almost impossible, as this drainage will create such a current at the opening of the lake that it will require their strongest efforts to force a boat against it, and even after overcoming this difficulty, they would have little to look at but white shores and barren rocks.
I remain, Mr Editor, Faithfully yours… R D Levinge, Carnagh
Thanks to Vincent P Delany for this.

I mentioned flooded fields, zoned for housing, here. Michael Geraghty has very kindly sent on this photo, taken recently in Athlone.
How nice to have a waterfront apartment. Though it may be a bit much to have it waterback, waterside, watertop and waterbottom as well.
If there is an award for sales skills amongst auctioneers, I wish to nominate Messrs DNG.

That’s Ballina, Co Tipperary, on the Shannon, opposite Killaloe.

The pontoon seems to be more severely affected than it was in the last big floods, on 22 November 2009.

Sometimes you have to wonder about politicians and their grasp of reality. Take, for instance, young Mr Adams, Sinn Féin TD for Louth. There he was in the Dáil the other day, talking about flooding on the Shannon, and saying (amongst other things):
No single agency is responsible for the management of the River Shannon. Will the Taoiseach give full responsibility to the OPW for management of the Shannon?
Can Mr Adams have forgotten that, under the Good Friday Agreement, a cross-border implementation body called Waterways Ireland, reporting jointly to the Minister for Fairytales in the republic and the Minister for Marching Bands [a Sinn Féin MLA] in Northern Ireland, is responsible for navigation on certain named waterways including the Shannon?
Giving the Office of Public Works full responsibility for the management of the Shannon would require renegotiation of the Good Friday Agreement [and perhaps some later agreements]. I gather that the members of HM Devolved Administration in Northern Ireland delight in doing that sort of thing, but reducing the powers of the largest of the cross-border implementation bodies might not be wise.

Here is the ESB’s Notifications page, with info on the rate of discharge from its hydroelectric dams and weirs. Today (14 December 2015) Parteen Villa Weir is discharging 440 cumecs (cubic metres per second or, roughly, ton[ne]s per second down the original course of the Shannon. That’s 44 times the 10 cumec usually discharged and more than replaces the 400 cumec diverted through the headrace to the Ardnacrusha power station. The Shannon is therefore running at its pre-Ardnacrusha levels and the Falls of Doonass have regained their power.
Of course if Ardnacrusha didn’t exist, its 400 cumec would be coming down the original course of the Shannon on top of the 440 cumec already there, which would make for interesting levels of flooding.
That ESB page has a link to this infographic, which shows the sort of information I was trying to get across here. I usually start from Leitrim [village]; the ESB starts slightly further upstream at Lough Allen. Note that the Shannon’s few locks are concentrated upstream of Lough Ree: between them and Killaloe are only two locks, at Athlone and Meelick, so the river’s fall is very slight.
Update 2018: the ESB has a new page with lots of interesting information here.
