Thanks Jim - I have now entered that into the survey online 'quick entry' e.g. at - http://www.dragonflies.org.uk/ I can do an area close to and/or around Free Lane area for the main survey of dragonflies/damselflies.. The grid reference closest to is - SD7813220805 - this is where I am going to spend most of my time. It is where the smaller river (don't know name) runs from Helmshore to Irwell Valley/Vale. Cheers Simon.
It's the Ogden, I think. That would put you in tetrad SD72V. If you put this in the search box on the Location page of the dragonfly atlas site it should show you the boundaries of the tetrad.
It would be great if you could check the ponds, rivers etc within it once a month or so.
I've an idea Dale Pollard (Dog Nobbler) lives not far from the location you gave.
