Cromwell Bottom Sighting

Morning all
Spotted a large water loving Mustelid by the weir between North Bank Loop and Tag Cut Loop on the river Calder at CB this morning (7.45 am). The animal was hunting below the weir sill and then disappeared into vegetation on North Bank. It reappeared some 5 mins later above the weir and swam off strongly upstream towards Lowfields Business Park. I had the animal under observation through bins for a good 10/15 mins and am certain of my ID. For obvious reasons I have not named the creature on a public forum and hope that anyone wanting to see such animal will be discreet and remember that the animals safety and well being comes ahead of anyones understandable wish to view it. I suspect a good place to look would be to park at Lowfields and walk downstream on the right hand bank of the river in the direction of Brighouse.
