00:00This is the Great Divide and that provides the watershed here to this catchment.
00:21Wallabadawa is looking like it's going to run out of its water, its groundwater that was.
00:25So the idea was to look around the catchment and see what's actually happening.
00:30And that's where this idea of these gullies incising came to import.
00:41The thought was if we can slow it down and try and get vegetation growing,
00:46because vegetation is the answer to it.
00:48The long term solution is to get good ground cover and get water in the ground.
00:59So the fact that we've got sediment and it's growing up has been a major achievement.
01:08On sediment here, it's accumulating.
01:11It's starting to work properly, it's starting to come up.
01:14And then associated with that we've got some pretty good vegetation.
01:17We've had a few guys at getting vegetation going.
01:23I think that the thinking of the community, you know, the fact that the community has come together
01:29and what I would call a place-based solution to a chronic problem.
01:33We do have to work out how we slow the movement of water across the landscape.
01:37We do know that over time, the climate change, the basin's going to get hotter.
01:41We're going to get more extreme events, so longer droughts, bigger floods, more variability.
01:47And so if we can look at ways to manage that variability, we're going to get better outcomes.
01:51One of the ways you can do that is look at how water moves across the landscape.
01:55So really impressive to see, even at just a very small scale, that you can slow that water down
02:00and you can get replenishment of the groundwater table, which is so important in a place like the Napa water.
02:05What we want to do is slow the water, repair the banks, and get some utility back into the floodplains.
02:14You're not building structures to build structures.
02:16You build structures for vegetation and for stability.
02:20And once you've got grasses and more vegetation, you've got stability.
02:25And that, you know, we can walk, you know, if somebody doesn't come in and actively wreck that,
02:31you know, that's there in a thousand years.
