The Reliable Surface Water in NSW dataset was created by the Department of Climate Change, Energy, the Environment and Water - Water Group in 2013 to identify areas in NSW with a reliable surface water supply.<\/span><\/p>

 <\/span>Land with reliable surface water was defined as areas:<\/span><\/p>

• buffering all regulated rivers and creeks by 150 metres,<\/span><\/p>

• buffering unregulated rivers and creeks with a 5th stream order or higher, by 150 metres,<\/span><\/p>

Reliable surface water mapping along with two other datasets (reliable rainfall of 350mm or more per annum for 9 out of 10 years, and highly productive groundwater) are used to identify land with access to a reliable water supply, forming part of the regional and site level assessment classification of Biophysical Strategic Agricultural Land (BSAL) at regional and site levels.<\/span><\/p>
