Stream Clearing
On Saturday, 6th May 2008 Jon Holmes (WDC), Dave Partridge (Glendale) and
four committee members formed a small working party to clear the brooks of
accumulated
debris. Older members will remember a time when the Luzley ran clear and fast,
but the water table in Warwickshire has fallen, resulting in slow flow. This
in turn allows silting, and subsequent colonisation by the plants of the banks,
exacerbating the slow flow. Couple this with winter branch fall and detritus
from the Fields, and the result is a clogged foul-smelling stream. Our job
was to clear as much as we could to get the water running freely again, but
this is not simple, for, unlike the Finham, the Luzley has a mud bottom.
Jon, suitably clad in waders led the team from the middle of the brook where
he was well sunk into the Luzley silt, and busy raking out a tarpaulin and
rotting hardboard; presumably from previous activities in the Fields. At the
first bridge, Jon and Dave pulled out nine inches of willow root stock and
accumulated debris. In total a whole truckload of material was removed. A sudden
gush of water, brown silt turbulence and the Luzley was flowing again - once
the silt settles we should have clear flow.
Then on to the Finham; a relatively easy job since it was cleared by us last
Spring. It's much improved since last year's clogs with a clearly visible stone
bottom, clear water and shoals of tiddlers. The willow that we pollarded last
Spring has wands 2-3m in length, and bears flowers. Treecreepers are active
along the banks of the two brooks, skipping up the trees in search of food.
Tadpoles are wriggling by the Lake edges. And finally, hybrid goldfish are
spawning in the Lake, especially down by the feeding boards by the Swimming
Baths.
We are hoping to arrange for another stream clearing this spring so keep an
eye out on the Activities page for a date.
