Heavy rain at the end of November caused the Gadloch to rise much above the fence next to the Auchinloch path. This is the worst flooding known in recent times, according to a long-time Auchinloch resident. The background to the Auchinloch path closure was given in an October post (see October archive). (See also ‘More news and pictures’.)
The pictures below of the Robroyston flood attenuation works, upstream of Gadloch, show very little water in the accumulation pond, relative to the potential volume, which can be judged by the height of the bank opposite. The outflow into the Standburn also looks much larger than the capability of the Gadloch outflow works to cope. (These pictures were taken within an hour of the previous Gadloch picture.) The obvious conclusion is that not much ‘flood attenuation’ is happening.
Blockage of the Gadloch outflow tunnel has previously been blamed for the flooding problem but the outflow from the tunnel into the Park Burn was recently observed to be pretty vigorous. (Comments on this post have been ‘enabled’.)
