Your best hope is to fish down and try and catch hold of the old wires or some other part of the pump, then pull it up. Find a stout metal hook, tie it securely to a 1/4-inch cord, then try your luck. You might just connect with a loop or hole on the pump and pull it up that way.
A century of water: As Winnipeg aqueduct turns 100, Shoal Lake finds freedom
The taps to Winnipeg's drinking water were first turned on in April 1919, but as the city celebrated its engineering feat and raised glasses of that clear liquid, another community's fortunes suddenly turned dark. Construction of a new aqueduct plunged Shoal Lake 40 into a forced isolation that it is only now emerging from, 100 years after Winnipeg's politicians locked their sights on the water that cradles the First Nation at the Manitoba–Ontario border. "The price that our community has paid for one community to benefit from that resource, it's just mind-boggling," said Shoal Lake 40 Chief Erwin Redsky.
