"The Historic Ditch Walk " began in 1876, when the Vaughn Agricultural and Mechanical Canal Company sought to provide irrigation by gravity flow from the nearby San Saba River to 2000 acres of land and to provide power for gristmills.

A huge dam was built across the Chagres ( cq ) River, creating the world's largest man-made lake, which controlled the torrential rains and provided enough water that the locks could run on gravity flow, without pumps to move the ships.

An automatic vacuum breaker in the milkhouse cyclically pulled milk from the cart into a glass jar using system vacuum, followed by a release of vacuum to atmospheric pressure, allowing the milk to flow into the bulk tank by gravity flow.

Another option is to separate a small portion of the reservoir by constructing a weir up to MSL along with an underground pumping station at to maintain gravity flow to the left bank canal side from the lower level dead storage water of the main reservoir.

Due to the gravity flow to Klingner Road, expensive sewerage pumps had to be brought in, power for the floodlights had to go underground to the main oval and the run-through tunnel was transhipped from Western Australia at a cost of $ 9, 000, which was still cheaper than buying one from the Eastern states.

Those to the west of the Idle drain into the river by gravity at a number of locations, but the region to the east of the river and to the north of Retford drains to a single outfall at Wiseton, where a pumping station pumps the water into the river when river levels are too high for gravity flow.

The storage in the tank or lake has been seriously affected since the catchment area contributing flows into the Surajkund ( lake ) from villages such as Anangpur, Lakkarpur, Ankhir and Meola Maharajpur has been used for extensive mining and for large habitations, which has disturbed the drainage system and thus obstructed the gravity flow of rain water from the basin into the reservoir.
