Hollow ponds has always been a boating lake.....its directly opposite Whipps Cross hospital in one direction and Snaresbrook Crown court in the other ......its also a well known pick up spot for woofters....apparently
The pakies go there for their summer holidays most years the amount of shit they throw in it id be amazed if theres anything alive in there.
