(NIWA) for the 2014 calendar year. As at the end of the 2014 period, this CCC network comprises 76 data recording sites in the Christchurch area, consisting of 20 rainfall, 24 water-level, 31 groundwater and 0 miscellaneous stations. These sites are either permanent or project (temporary), most are telemetered via either cellular (GPRS) links or UHF radio. The remainder are manually downloaded or measured on a routine data collection basis (groundwater sites). Some sites are ECan / CCC ‘data shared’ sites or treated as additional datasets from NIWA specific sites, transferred from the NIWA climate database. For the 2014 period, data integrity was again maintained at a high level across most sites, despite interruptions from ‘rebuilding activity’ in the Christchurch area following on from the 2010 - 2011 earthquakes. Total missing record was again kept very low for the 2014 period at 0.71 % of the total hours recorded for all telemetered sites. Such levels of missing record are considered to be very acceptable when compared with New Zealand and international data collection standards. Additional work outside the Hydrometric Network Agreement has also been reported, detailing various projects and tasks that NIWA has assisted the CCC to complete during the year. These have ranged from additional labour orientated duties (flow gauging, new site installations) to sharing of expertise and advice (data handling & archiving, software support, hydrological site design). There are 10 sections that describe the data in this report. (a) Section 2 provides an overview of the weather during 2014 and a commentary on significant rainfall events which occurred during the year. (b) Section 3 outlines the quality assurance checks undertaken on the data and provides statistics on project data capture performance (c) Activities associated with the operation of rainfall, water-level / flow and groundwater sites are described in Sections 5, 6, and 7 respectively. (d) Activities associated with miscellaneous sites including evaporation, temperature (air and water), and any additional sites, are described in Section 8. (e) Proposed work activities that are anticipated by NIWA to be completed in 2015 are described in Section 9. (f) Section 10 details recommendations to further improve the management and operation of the hydrometric network. (g) A summary of any faults experienced during the year is detailed in Appendix 1, and an updated asset list defining the structures, instrumentation and other equipment at each site, is given in Appendix 2. To provide the annual summary of quarterly reports on the operational performance and data integrity from the stations of Christchurch City Council’s (CCC) hydrometric network, as managed by the National Institute of Water & Atmosphere Ltd.
