  • Proposed Amendments to LWRP Schedule 17: Salmon Spawning Sites
    Memo Date 28 May 2019 To Environment Canterbury Planning Team CC From Jarred Arthur (Scientist – Water Quality and Ecology) Proposed amendments to LWRP Schedule 17: Salmon Spawning Sites Purpose The Land and Water Regional Plan (LWRP) outlines several policies and rules that control activities in and adjacent to salmon spawning habitats of high value. These 32 ‘significant’ salmon spawning sites are listed in Schedule 17 of the plan. The advent of new spawning information means that Schedule 17 does not recognise a number of spawning sites important to maintaining Canterbury’s internationally recognised salmon fishery. The following memo is prepared by the Environment Canterbury science team with support from the Central South Island and North Canterbury Fish and Game councils. It outlines a proposal to amend Schedule 17 of the LWRP including: • adding 31 new sites; o 22 established from new Fish and Game spawning habitat data and information. o nine situated in the Waimakariri River Catchment currently excluded from the current schedule due to the Waimakariri River Regional Plan (WRRP) controlling land and water activities in these areas. • updates to three site descriptions and coordinates for existing Schedule 17 sites – proposed change in length/area of the existing sites; • updates to ten site descriptions and coordinates for existing Schedule 17 sites – no resultant change in length/area of the existing sites; and • a revision of the LWRP Planning Maps to show the proposed amendments to existing spawning sites and newly recommended spawning sites. Background Chinook salmon (Oncorhynchus tshawytscha) are largely confined to Canterbury with only small populations found in Otago, the West Coast and Marlborough (Unwin, 2006).

The nutrient limits are a way of managing diffuse sources of nitrogen loss in the catchment. This report describes the current state of groundwater quality in the lower Waitaki catchment to inform that process. The technical team has used test scenarios to explore groundwater quality under different management actions and nitrogen loads. This is discussed in a separate report (see Etheridge and Scott 2015). The upper Waitaki catchment has two major depressions, the Mackenzie and Omarama basins. The area may also be further divided into smaller sub-basins, based on geological features and glacial movements. The surrounding hills have provided the deposits which form the aquifer material, but various glacial and interglacial periods have resulted in substantial heterogeneity. Quaternary deposits host the main aquifers in the area.
