    Apparently sitka spruce plantations and associated drainage works a few km upstream of Clifden are likely to have contributed - previously boggy land wouldn't have drained so quickly.

    Would boggy land not already be saturated and worse? I've no idea, just an assumption.

    It's the difference between a sponge (boggy land) and a cloth (plantation land) one can absorb a lot and release it slowly the other is saturated very quickly and absorbs no more

    These 1 in 40 year events seem to be occurring 1 in 40 days now.

    Connacht was not included in last nights warning it went up very quick this morning but either way what could you have done with that amount of rain. I never saw such colors that were on the radar in the early hours.

    So they failed to predict the track of the most intense rainfall.

    those showers look very intense moving into Galway and Mayo.They could easily dump another 5 to 10mm of rainfall on top of everything that fell last night.

    Terrible not including Galway in the weather warning. Only updated at 9am but we had heavy rain overnight (Letterfrack) and had floods already by that time.

    Jez just checked them now and they are growing in intensity could be a lot more flooding, hope not heart goes out to anyone who gets their house damaged by weather.

    Some person on local radio who lives in Clifden said that the river has never flooded like this in his lifetime, so something wrong upstream

    Some blame being laid on plantations upstream

    they are looking seriously at issues like this in the steep sided valleys in west yorkshire

    Coillte never seem to learn anything.

    Coillte, and by extension the Irish taxpayer are currently paying €15k a day in fines to the EU for the last 3-4 months for the poor management of uplands in Derrybrien in South Galway, which has been responsible for flooding there for years since the building of wind farms.

    They've been warning about this for ages. Our bare uplands and stripped bogs will only lead to more and more of this.

    The forestry plantations will have reduced the floodwater peak from what it would have been otherwise - the root systems slow down the runoff. Now, if there was a large swathe of recently felled forestry, that would revert the behaviour to pre-forestry runoff speeds.

    Bogs can take in a lot of water for sure, but only up to a certain rate. Above that rainfall rate the extra runs straight off. Source? I've a mate who is a forestry manager, and I've also observed this behaviour after 25 years of watching floodwater levels on Irish streams with my kayaking background.

    I would suspect that if it were not for the forestry work, there would have been a mudflow/bogflow situation with the peat mobilising similar to that at the Dawn of Hope Bridge in Sligo and that would have been significantly worse for the Clifden residents.

    Also - the videos linked above would have been *so* much better in landscape mode instead of the dumb portrait mode most people record in. We would then have been able to get a better scale of the damage and destruction without a need to pan around as much.

    It's beyond me why people film in portrait mode it's a waste of a good capture of any incident
