Save Our Water Day - Hartebeest Dam

Thursday, 12th July 2018 (all day)

Location: Hartebeest Dam

Bring a rake and roll of bin bags. 

You may choose your own point around the dam or on the river.

As the plant anchors in mud please use all safety measures possible. They have runners so pulling them should be easy but they may be grounded which could make the task difficult.
Seeds are viable for up to 30 years so get as much as you can out.
Populations can double in size in two weeks. When not controlled, it will rapidly and thoroughly cover entire surfaces of lakes and ponds – dramatically impacting water flow, blocking sunlight to native submerged plants, and starving the water of oxygen; often killing wildlife such as fish and birds.

It can change water chemistry, affect flora and fauna and cause significant increase in water loss due to evapotranspiration. 

The threat to us is clogging of intakes of irrigation, hydropower and water supply systems. health problems: malaria, schistosomiasis and lymphatic filariasis.

If you own any of the following - land-based ‘clamshell’ bucket cranes, draglines or booms or, alternatively, water based machinery such as mowers, dredges, barges please help. Bakies needed to transport the stuff to a landfill area (suggestions please) Mats of water hyacinth can be enormous and can have a density of up to 200 tonnes per acre. Garden shredders needed to chop.
