Only one pond in Victoria Park,

That's my memory too HORT. That and a fountain in the grounds of what used to be the museum building

There's Spoggy Brook in Queens Park, full of ducks these days and fenced off.

The wildflowers are gorgeous at the mo, I was there the other day

Can you actually physically reach Spoggy Brook without trespassing? My memory, admittedly from the 1950s is that you could look down at it from Dilloway Street but to physically get to where it ran into the culvert under the park meant trespassing through the sacrosanct Park Keeper's area at the north end of the park

The brook is known as Windle Brook these days but at one time it was called Spray Brook.
Hence Spray Street and the Sparayhurst Club.

Is it accessible without respassing?

The big dare in the 1950s, which I never did, was getting past the Park-keepers and into the culvert and re-emerging through a manhole about 100 yards further towards Boundary Road

It is not accesable. Fenced off within the park.

What is the huge canvas like structure that has been erected near the Boundary Road entrance? Anyone know what it is for?

Its a Padel Tennis facility called Soul Padel,...........A racket sport combining elements of tennis and squash, played in doubles on an enclosed court with walls.

I am amazed. I have never heard of this.
Anyone on here ever played it?
