Three Streams Reserve is a park on Dairy Flat Highway in Lucas Heights, North Shore City, Auckland, rated 4.1. A reserve built around streams like this one rewards a slower pace, since a track that follows the water tends to be more about what you notice along the way, birdlife, native plants, the sound of running water, than about covering distance. Ground near a stream bank is usually the first to get slippery or undercut after rain, so it's worth being more careful with footing close to the water's edge than on the drier parts of the track. Water quality in an urban stream can also drop noticeably after heavy rain, as runoff washes in from the surrounding catchment, so it's not somewhere to treat as clean for swimming or letting a dog drink straight after a downpour. On Dairy Flat Highway in Lucas Heights, Three Streams Reserve is that kind of local waterway walk.
