Back in the eighties the ponds at Bowker Vale were threatened with being drained and turned into a housing development site . That threat was successfully averted and in the intervening years the wildlife value of the ponds has increased enormously . Now the ponds are under threat again with a developper wanting to drain one of the ponds and turn the other into a " feature " in the middle of a housing estate linked to Blackley New Road by a monstrous bridge over the Irk . This would destroy the ecological value of the site and destroy a green haven at the heart of the city . Crumpsall's Labour Councillors are determined to fight this every step of the way and make sure it doesn't happen !
