A very detailed history of this area can be found on the Brook Waimarama Sanctuary web site - http://brooksanctuary.org/about/history
Unfortunately at the time of placement the Sanctuary is closed to the public due to some rather controversial pest control operations.
You can still walk the 14km Fencelince Track that marks the perimeter of the Sanctuary.
Here I have place a nano cache on a relic of the areas previous purpose - that is - supplying water to Nelson. I'd suggest daytime visits only here.
