The dam receives its water via the Tugela-Vaal Project which is a pumped-storage scheme involving the net transfer of up to 630 million cubic metres (510,000 acreÂ·ft) of water from KwaZulu-Natal. This is stored in the Sterkfontein Dam and released to the Vaal Dam via the Wilge River when needed.he Sterkfontein Dam is a highly effective reservoir, since it has the depth to store a large amount of water, with very little loss to evaporation. The Vaal Dam lake (reservoir) by comparison has a large surface area and is relatively shallow, which results in a higher rate of evaporation.
Poor quality hay or grass can lead to hay belly in horses. The digestive system of your horse is made to extract nutrients from grass and hay. Horses donât have a way to break down fiber, however bacteria in their large intestine will ferment the hay or grass.
Grass hays have a lower protein content, and are suitable for easy keepers, and other horses that do not require the extra calories. In general, grass hays are less expensive than legume hays, but because of demand by the horse market in some areas, grass hays can be more expensive.escue hay can cause toxicosis in pregnant mares when they eat tall fescue that is infected with an endophyte fungus, Acremonium coenephialum. Both the mare and the foal can be affected. Before feeding fescue hay to pregnant mares, a horse owner should make sure that the hay is free of the endophyte fungus.
