Most sites were monitored bi-monthly, but five further worst quality followed by the sites (Clutha River/Mata-Au at Luggate, Millers Flat, Balclutha, the Kawarau upper Waipahi River River, and the Shotover River) were monitored monthly by NIWA as part of the National River Water Quality Network (NRWQN). Sites were classified • The Dart River had fair using a water quality index. water quality in 2011 due to naturally high sediment Very Good All six values comply with guideline values levels (elevated turbidity) and Good Five median values comply phosphorus Fair Three or four median values comply • Both Didymosphenia Poor Two or fewer median values comply with guideline values geminata and Phormidium were present in the Lindis River • All macroinvertebrate monitoring sites had at least average SQMCI scores • Generally, most fish monitoring sites had at least two species with trout being found at all but one site. Water quality index ORC uses a water quality index (WQI) derived from medians of six indicator variables, turbidity, dissolved oxygen (percent saturation), ammonical nitrogen (NH4), nitrite-nitrate nitrogen (NNN), dissolved reactive phosphorus (DRP) and Escherichia coli (E. coli). Median values of the six values are compared with ANZECC (2000) and MfE/MoH (2003) guidelines, enabling classification of water quality into one of the four groups. 1 Clutha River catchment February 2012 Clutha River catchment.indd 1 14/02/2012 4:04:07 p.m. Clutha River catchment.indd 2 Clutha Rivercatchment 2 Mill Creek instream values. of effects-basedstandardsfor a proposaltointroduceseries is currentlyunderreviewwith The OtagoRegionalPlan:Water ANZECC guidelinevalue. the graphs)depictrelevant The horizontallinesinred(in effects areconsideredlow. the risksofadversebiological values specifyalevelbelowwhich m abovesealevel).Thetrigger water courses(lessthan150 outline triggervaluesforlowland The ANZECC(2000)guidelines nutrients Guidelines for Waipahi River Waipahi River Waiwera February 2012 Burn hadthehighestNNNconcentration. farming ordairyiscommonplace,asaretiledrains.TheHeriot of NNNinsouth/south-westOtagoarewherehighintensitysheep farming ordominatedbytussocklands.Thehighestconcentrations Otago andtheCluthaLakes,whereland-useislow-intensitysheep growth.

If a gate is open or closed leave it that way. • A farm is the owner’s livelihood and if they say no dogs, then please respect this. • When driving on riverbeds keep to marked tracks or park on the bank and walk to your fishing spot. • Never push in on a pool occupied by another angler. If you are in any doubt have a chat and work out who goes where. • However, if agreed to share the pool then always enter behind any angler already there. • Move upstream or downstream with every few casts (unless you are alone).

Box 56, Dunedin New Zealand WLM Report Number: 201 2008 1 WILM 403-Practical of Wildlife Management Jess Harris Executive Summary The Nevis River carves its way through an intermontane valley within the Central Otago Region of New Zealand. The purpose of this report is to introduce the Nevis Valley, review and discuss the current values of the Valley and as a result demonstrate why the River should be completely protected from any potential hydro electric development. The Nevis Valley is commonly described as an isolated, open-spaced, golden landscape, scattered with remnants of past mining and farming settlements. These days the valley is utilized by a range of recreational uses such as, fishing, kayaking, four wheeled driving, and picnicking. More specifically, it is the solidarity and the outstanding back country landscape that anglers, both nationally and internationally have come to value highly. The river also provides the opportunity to see and catch trophy trout. These such values are what Otago Fish and Game Council are seeking to preserve. In 1997 the Water Conservation (Kawarau) Order (WCO) was created.

This publication may be reproduced in whole or in part provided the source is fully and clearly acknowledged. ISBN: Published Prepared by Rachel Ozanne, Otago Regional Council Reviewed by Adam Uytendaal and Dean Olsen, Otago Regional Council Water Quality Study: Waiwera River Catchment i Technical summary The Waiwera River is a medium-sized river, which rises in the Wisp Range and flows in a northerly direction to its confluence with the Clutha River/Mata-Au downstream of Clydevale. The river is fed by rainfall of up to 1400mm per annum in the Kaihiku Ranges, while the lower catchment receives lower levels of rainfall (<700 mm per annum). The objectives of this report are to: • Assess water quality in the Waiwera Catchment and identify where Schedule 15 limits in the Regional Plan: Water (RPW) are exceeded. • Assess spatial and temporal patterns in water quality and to relate water quality patterns to land-use activities, where possible. • Assess in-stream habitat quality and macroinvertebrate communities. Most of the intensive farming in the lower Waiwera Catchment takes place on very poorly drained soils, farming in these areas would not be possible without the construction of extensive artificial drainage (tile drains) to convey water to the nearest watercourse, in the upper catchment to the west of the Kaihiku Ranges the land supports extensive sheep and beef grazing.

Its headwaters are in the Harris Mountains, and in the lower reaches it is bordered by the Crown Range; it flows in a south-east direction, joining the Kawarau River near the township of Arrowtown. The climate is typical of Central Otago being characterised by cold winters and warm, dry summers. There are 22 existing surface water takes in the Arrow River catchment, with a total allocation of 2.03m³/s, although the measured usage does not exceed 1 m3/s and the average take is approximately 0.55 m³/s. The objective of this report is to present the findings of further investigations into the hydrology, ecology, and irrigation practices of the Arrow catchment since the last published report on this topic in 2012 (Management flows for aquatic ecosystems in the Arrow River (2012).

She was actively involved in all aspects, from monthly meetings, ;ield trips, research projects to attending conferences. For over 20 years Lesley did the twice-yearly counts of waders at Aramoana. She also spent many hours out on the estuaries with fellow birder, Peter Schweigman, to resight banded godwits and spoonbills, which provided important data to learn about their migration patterns. For over 10 years, fortnightly during spring, she was part of teams that counted birds at Orokonui, both before and after the fence was constructed. For 5 years, Lesley took part in many surveys throughout Otago, gathering bird sightings for the previous NZ Bird Atlas. Lesley coordinated our Millennium Project, a survey of king;ishers throughout Otago. 5 Minute bird counts at Mt Watkins Counting Godwits on Aramoana Saltmarsh Peter, Lesley and Lala counting at Hawksbury Lagoon Lesley’s enthusiasm and delight in watching birds made her great company on the many ;ield trips we shared. Her Birds NZ friends will each have their own happy recollections of birding with Lesley. 3 Ornithological Snippets In addition to the Marsh Crakes at Tomahawk Logoon mentioned last month, which have been seen by numerous observers, Mary Thompson saw 2 at the north end of Lake Dunstan on 21st March.
