Description: The ability of native fish to migrate in NSW has been significantly constrained through the construction of dams, weirs and road crossings within NSW waters. These structures can act as barriers to fish and have contributed to a 90% decline in native fish populations since European settlement. Suitably designed fishways are a proven barrier mitigation technique and their monitoring has repeatedly demonstrated that fishways are among the most effective fish recovery techniques in terms of size and speed of native fish population recovery. This layer identifies the location and type of fishways throughout NSW The dataset does not include early submerged orifice fishways from are known to be ineffective for Australian native fish, being primarily designed for European species.
