Seawater in the dry fjords won't effect the freshwater. The locations looked at are hard rock areas with minimal leakage. The floor and sides would be sealed, anyway.
As to the land "below" these dry fjords, I've been to a few of these areas and there is very little between the valley and the sea, the land is marginal and little used by humans. The only thing would be the "rare snails" people keep finding. They really help the economy.
I've also heard this idea mentioned before, the difference now is that the mentioners now are people with degrees and major business acumen rather than a local farmer who can think outside the box.

Can you publish the studies you have done so far, so that people can make their own mind up?
I share the scepticism of others that you are trying to sell this idea to the general public and to politicians, before engineers and technologists, who are better able to evaluate the likely cost/benefit.
Unfortunately for us electricty users it is. And it works like this. Under the Alternative Energy Requirements the monopoly network owner and generator in Ireland (the ESB) was required by law to buy wind generated electricity. In an open market, they would buy off someone:
- Cheaper and
- able to guarrantee delivery
That would be a gas turbine most likely.
The the CER (the people who regulate the electrity monopoly in Ireland) keep the price inflated to allow the ESB and these "prefered alternative suppliers" to turn a profit.
Here is an interesting article in the Indo.
Economy will pay high price as ESB turns to wind power - Irish, Business - Independent.ie
This is a most interesting piece:
Alarmingly, the report [from the Energy Regulator] indicates that oil prices would have to hit around $200 a barrel if there are to be significant electricity price savings from the installation of large amounts of wind power on the national grid
It isn't feasible.
The number of these things you would have to build would be ridiculous.
You would have to build a large excess of them to guarrantee that they had water in them when the power was needed (remember, relying so much on wind means you can't guarrantee that you will have had the excess power to fill them).
And then add up the cost. You are effectively building two generating systems. One hydro and one wind and both of them with a large amount of excess capacity over peak demand to counter for the uncertainty factor (othwerwise put up with regular blackouts)
Those countries that use hydro a lot (Norway, Brazil Canada mostly at more than 50%) have their hydro power replenished by rain/snow melt etc. and need to have considerable back up to boot.

Sweet demons, yer man, either Ivan or the other guy, speaking afterwards, got it right, 'For every solution, there's someone who will make a problem'. Paraphrasing.
I get the impression that in Ireland, we shouldn't come up with any ideas. And what makes this worse in this case is that there is no prototypes to be developed and tested, as for wave power, it's actually old technology composed of 'off-the-shelf' components.

This is tested technology and there's no reason in principle why it wouldn't function. Water would only be released when wind speeds dropped. There could be other windfarms supplying in the windy periods.
Denmark is using electric cars to mop up excess from windfarms - they're installing 50,000 charging points.
There are all kinds of problems with the proposal and I think the time scale and claims for filling 80% of need are crazy. The biggest problem at the moment is the inadequacy of the grid.
It isn't whether they will function, but whether there is enough water when needed. The water only gets where it is needed from an excess of electricity produced by the proposed wind farms. The windfarms only produce the excess electricity when the wind is blowing at the right speed across enough of the country at the same time as demand isn't too high.
Goes to show how crazy and wasteful Denmark's policy is. The best analogy I can think of is cooking too much food for your family each day and proposing that the most cost efficient solution to the problem is buying a few dogs to eat the remains.
