When the River Wey exits Radipole reserve it passes through the Boating Lake, then encounters a sluice system at Westham Bridge before exiting into the saline environment of the inner harbour. There's a footbridge just on the marina side of the bridge which provides a view of the sluice and the inner marina.
The footbridge has been adopted by a Common Tern. It sits on the handrail looking for tiny fish, and when it sees one dives down to catch it. It allows approaches of down to 5 feet - too close to focus.
The inner marina is also home to a shoal of about 100 mullet of some description.
The Common Terns have taken up residence on one of the boats - second on the right I think, judging from the white stains!
