2014 – April Adventures

Please see the invitation below from the Environment Agency to FREE Practical River Habitat Workshops.  N.B. River Misbourne focused on 28th April and 2nd May.  If you would like a place, please contact Nancy direct asap before 14 April and, perhaps, let me know that you have used one or more of our reserved places.  If you advised last year that you would be interested, you still need to apply now.

You possibly remember our discussions with Affinity Water last year, their consultation in which we urged you to join, and subsequent publication of their draft plans for the period 2015 – 2020 submitted for Ofwat approval?  We have recently received an encouraging and detailed update saying the following is being positively considered by Ofwat for confirmation later this year
Design and construct new pipelines and other measures during 2015 through to 2017 enabling a reduction in abstraction from Amersham of 3Ml/d in 2018 and a reduction from Chalfont St Giles of 2Ml/d in 2020.   
Use of this (up to 5Ml/d) for augmentation during low flow drought periods is still under debate, but the reductions in abstraction would, in any case, be all the time.
Extended monitoring will be required to demonstrate the benefits to both flow and ecology from the reductions in abstraction. MRA assistance in helping this work in the Misbourne will be welcomed.
Affinity want to work closely with MRA in deciding how and where the most benefit could be gained from future habitat and flow improvement work.
Affinity hope for MRA’s active involvement in planning and installation of these works.

Beginning of the month groundwater readings will be on the website soon and will show a slight reduction on last month’s peak.  We can now see that the peak has been almost exactly the same level as in early 2001 but shorter in duration – these two events being the most severe since our own records began in 1992.

We had a good afternoon last Saturday and made a real impact on the “backstream” at Chalfont St Peter which is now running clear and showing some sections of clean gravel bed.  Thanks to the weekday squad for disposing of the large piles of arisings, including many branches and 6 tonne-bags of brush.

Our next workday will be Saturday 26 April: please let me know if you would like to join us.   We will be back on/in the river proper and, depending on numbers would expect to have several teams from Bottom House Farm Lane downwards.   Provisionally, the one after will be Sunday 25 May – (to be confirmed).  We will have a “not-a-meeting” at The Greyhound on Tuesday 22 April at 7.45 p.m. – all welcome for a drink and a chat.
