Appendix 6 Volume Three (c) identified on Freshwater Management Unit Maps 1, 2, 3 or 4, and further described in Schedule 3; or (d) is not specifically defined. ** Monitoring sites are mapped on Freshwater Management Unit Maps 1, 2, 3 or 4. *** Levels and elevations are expressed in metres above Mean Sea Level (mamsl) in terms of the Marlborough District Council Rivers and Drainage datu m. 3.1 The minimum flow for a FMU not listed in Schedule 3 is calculated as follows: (a) for a river with a mean flow of less than or equal to 5m³/s, the minimum flow is 90% of the mean annual 7 day low flow. (b) for a river with a mean flow greater than 5m³/s, the minimum flow is 80% of the mean annual 7 day low flow.
