Today, Friday 12th October, all of the wildlife has finally departed.
The lake is, to all intents and purposes, now completely drained of all water.
All that remains is the silt, which is to be removed.
I will check this evening to determine whether any of the ducks have returned to nest.
Having been to the lake to check on the presence, or otherwise, of wildlife, the excavation team now having left and enclosed the site for the weekend, the lower end of the excavated area is beginning to refill with fresh clean up-stream water. It is being contained within a sump, so will presumably be pumped out on Monday morning, to allow the dredging work to proceed.
The heron has just flown over what remains of the lake: it made absolutely no attempt to circle, as it usually does on a reconnaissance flight, before gliding down to the waters edge.
As usual, when it is in flight, it has been mobbed by several crows and has veered off, back towards the river. It is encouraging that the heron appears to be continuing to check out the lake: which suggests that he may return once the works are completed.
Interestingly, I have seen no evidence of stranded fish, which suggests that the pickings for the heron are small, but that he is an effective fisher.
I will make periodic checks on the return of any form of wildlife during the course of the weekend. The heron has just flown over again, having been over only an hour ago; so I’ll be surprised if at least one or two of the ducks do not return, when they realise that there is fresh clean water in the excavated area. And I imagine that the now freshly exposed lake-bed, which has not yet been excavated, will prove to be a valuable feeding ground to some species of mammal, bird or fowl.
By this morning, Saturday 13th October, the lake has completely refilled, overnight.
The ducks are back, as is one land-gull.
The ducks look hungry, having vacated the lake and abandoned their food source yesterday; so they have been provided with half a loaf of bread, which it appears was very gratefully received.
They do also however look very pleased to be back. And I noticed that the inlet end of the lake is brimming with sticklebacks which have presumably been marooned in the blocked off up-stream section. So the ducks are not going to be short of food for long.
I find it amusing that the ducks and the land-gull immediately make for their roosting posts. Submerged, or partly submerged branches, where they can sit and preen in comfort. In shot Nos. 4 & 6 of this group, you will notice that they are also joined by a chaffinch. I didn’t spot it when I took the shots (about 50 yds away)
