Construction of a Water-Level Meter

Well owners depend on ground water but typically don’t know how to monitor it. Water level measurements can tell a well owner if their water is secure or if their well is developing a problem. More specifically, water-level measurements can determine the effects of neighbours pumping their wells and the difference between winter recharge levels and summer lows. This report gives instructions on how to build a water-level measuring meter.

Environmental Assessment of Ahuriri and Porangahau Estuaries

As the interface between land and sea, intertidal, estuarine and fringing coastal habitats are distinctive and dynamic environments. Ahuriri Estuary was formed in the wake of the 1931 earthquake, the Ahuriri Estuary (Te Whanganui-A-Orutu) is located in the area of the former Ahuriri Lagoon. Ahuriri Estuary is listed as a Significant Conservation Area under the Regional Coastal Plan (Hawkes Bay Regional Council, 1999), and a Wildlife Refuge that offers protection to areas between the Southern Marsh, Westshore Lagoon and the estuary from the low level bridge to Pandora Bridge.

Recreational Water Survey

Thirty sites were monitored as part of the 2007/08 Recreational Water Quality Monitoring Programme. These included fourteen marine sites, seven freshwater rivers, eight estuarine/lagoon sites and one freshwater lake. In addition, the water quality at 5 shellfish gathering sites were also sampled. This annual programme enables Council to assess the microbiological water quality of popular bathing areas, and elucidate trends in water quality throughout the region.

Thirty sites were monitored as part of the 2006/07 Recreational Water Quality Monitoring Programme. These included fourteen marine sites, seven freshwater rivers, eight estuarine/lagoon sites and one freshwater lake. In addition, the water quality at 5 shellfish gathering sites were also sampled. This annual programme enables Council to assess the microbiological water quality of popular bathing areas, and elucidate trends in water quality throughout the region.

Thirty sites were monitored as part of the 2005/06 Recreational Water Quality Monitoring Programme. These included fourteen marine sites, seven freshwater rivers, eight estuarine/lagoon sites and one freshwater lake. In addition, the water quality at 5 shellfish gathering sites were also sampled. This annual programme enables Council to assess the microbiological water quality of popular bathing areas, and elucidate trends in water quality throughout the region.

Twenty-seven sites were monitored as part of the 2004/05 Recreational Water Quality Monitoring Programme. These included twelve marine sites, seven freshwater rivers, seven estuarine/lagoon sites and one freshwater lake. This annual programme enables Council to assess the microbiological water quality of popular bathing areas, and elucidate trends in water quality throughout the region.

Twenty-seven sites were monitored as part of the 2003/04 Recreational Water Quality Monitoring Programme. These included twelve marine sites, seven freshwater rivers, seven estuarine/lagoon sites and one freshwater lake. This annual programme enables Council to assess the microbiological water quality of popular bathing areas, and elucidate trends in water quality throughout the region.

The 2002/2003 recreational water quality monitoring program included twenty five recreational water sites around Hawke’s Bay. This is the tenth successive year the Hawke’s Bay Regional Council has monitored popular bathing sites in the region over the summer period, from mid-November to mid-March. There were ten marine, five freshwater and ten estuarine or tidal sites monitored.

The 2001/2002 Bathing Beach Monitoring program included twenty four recreational water sites around Hawke's Bay. This is the ninth successive year the Hawke's Bay Regional Council has monitored popular bathing sites in the region over the summer bathing period from mid-November to mid-March. There were five freshwater , eleven marine and eight estuarine sites monitored.

Twenty-seven sites were surveyed for the 2000/2001 summer as part of the programme to assess the quality of the recreational water in Hawke’s Bay. Another initiative that was trailed was a beach classification system. This was derived from the World Health Organisation “Annapolis Protocol” and modified for NZ use by various associates of the Marine Bathing Working Group (MfE initiative). In general terms it is an assessment of the beach’s suitability for recreational use based on microbiological quality (over 5 years), and catchment assessments.

 

Ruataniwha Pre Feasibility Tonkin & Taylor Report

This report presents the results of a prefeasibility study for water augmentation opportunities on the Ruataniwha Plains in Central Hawkes Bay, focussed on surface water harvesting and ability to service, in round terms, up to 40,000 hectares gross of irrigable land.  Following a map-based scoping exercise a shortlist of 14 sites were selected for further exploration. Limited field investigations have now resulted in 6 possible storage dams being identified with potential to service the full demand across the 4 zones.  The study has been carried out for Hawkes Bay Regional Council (HBRC) by Tonkin & Taylor Limited, Environmental and Engineering Consultants in association with locally based agricultural and horticultural consultants, AgFirst NZ Limited.  Further studies will be conducted throughout the Ruataniwha Water Augmentation Feasibility Study which is now underway.

Wetland Reports

Wetlands are an integral part of the Hawke’s Bay environment, and have a valuable role in water regulation, filtering pollutants and excess nutrients, and providing habitat to a number of rare and threatened species. However these areas are also vulnerable to threats from drainage, diversion of water, discharges, stock access, and invasion by plant and animal pests. Bi-annual monitoring is undertaken at Hawkes Bay’s priority wetlands, to determine the effectiveness of Council’s wetland enhancement programme. Wetlands were monitored for changes in the abundance and diversity of native vegetation and fauna, the level and quality of the water, and for the presence or absence of any pest species. If you require maps for any of these wetland areas please email wetlands@hbrc.govt.nz.
