    With the recent mooted extension of the dam wall at Warragamba which will substantially increase its capacity how will this impact on low lying areas on the floodplain? Linky

    • Will the flood maps be redrawn?
    • Will it open up more land for development?
    • Will greater density be permitted (smaller subdivisions or more units)?
    • Is it going to impact prices in areas like Richmond/Windsor? (Or northwest sector)?

    Why raise the wall when you could just release some water? ?o_O

    Wouldn't everything downstream remain as is. It's the storage buffer level that would be crucial to prevent flooding.

    I call election bs

    Greater storage capacity will allow for greater population. Flood mitigation is secondary as you pointed out, can be controlled.

    Capacity is good. But the dam greens hate dams and dam water:eek:

    I just saw the dates are for 2018 onwards. They just finished the deep suction pipe thingo project a few years ago which extended the straws to the bottom of the bucket:cool:

    Shifting the drain holes to lower down in the dam increases the capacity without any visible detriment whereas raising dam walls will incrementally increase the flooded area behind the dam.

    They would release more land for Development, factoring some of the cost of the land into the development cost of the land. Would also allow some government land to be sold off I expect. Sounds like a win win situation for the government. It won't help first home buyers, although they will claim it will. Just my cynical view.

    Note - I'm also opposed to unnecessary flooding of upper parts of the catchment. The dam is big enough. They spent $$$ years ago raising the dam wall and putting the extra spillway in place.

    Upstream is rife with inbreeding so the higher the better! :p
