Thread: Allier river levels?

  1. #1

    Default Allier river levels?

    On our way to the Allier, Massif Central, France today! Any info on what levels are needed to paddle around Langeac, any info on dam releases please? Many thanks.

    If you can float your boat at Langeac, you'll be fine. My guess is they release from the upper dam most days but hold back the Monistrol dam one day.

    Been looking at gauges for a trip next week as we might tag a day or 2 on the Allier onto trip depending on levels etc. Struggling to work out the gauges.

    Looking at this site it would appear that Monistrol down is ok but the Jewell is not. Seems to be based on Prades gauge from Monistrol down but Nouveau Monde above for the Jewell.

    http://www.eauxvives.org/en/niveaux/en-direct

    River App on the other hand uses the Nouveau Monde gauge for all the sections listed and shows the Jewell as runnable.

    I'm working on the basis that if Monistrol section is good the sections below will be ok too but a Jewel run would be nice if it's not a complete scrape. Looks around 0.7ish
    at the moment.

    Anyone

    Have you tried http://www.vigicrues.gouv.fr (pretty extensive and the graphs for each station are fairly clear - you can add the flood levels to get an idea as to what is "normal" and what is a "flood")

    Yes I use that and the Eauxvives site above uses Vigicrues gauges. It was more the point that Eauxvives appears to use the Prades gauge for Monistrol down as opposed to the Nouveau Monde gauge which is used by River App. There have been a few occasions when I've been checking where Eauxvives has the Monistrol section running good when other apps have had it as low along with the Jewell section but this is based on the Nouveau Monde gauge.


    I guess I'm trying to work out if the river below Monistrol gets a release even when the Jewell section may be low/scrape.

    Your last statement John I think is very possibly. There is a separate dam above Monistrol with a relatively small reservoir providing hydro to some industrial unit. When we have been there it seems to be shut for one or two days like Sunday and Tuesday or something daft like that. The upper section is controlled by the Naussac which presumably tops up the lower reservoir.

    It's quite tedious to do but if you use 4-Paddlers.com you can find graphs of levels/flow rates for the two sections and click between them to see how they compare. The times when the Monistrol dam is closed appear obvious albeit not as regular as my last post suggested but they really don't seem to relate to the levels on the upper river.

    Sorry, but it is in German so, unless this is your strong language, you will need a bit of imagination to navigate the site.
