River Values Assessment System (RiVAS and RiVAS+), is a tool that allows the ranking of different rivers for different values in a region or district to be made.
The River Values Assessment System (RiVAS) was applied to the irrigation value in Gisborne district. An expert panel used the system to rank rivers from high to low in terms of their relative potential for providing water for irrigation. Eight river sections were analysed and of these one, the Waipaoa, was considered of regional significance with the rest being of local significance.

Trends and observations in landuse on the Poverty Bay Flats 2007 - 2013
H Telfer (Gisborne District Council)
Gisborne District Council has completed a survey of the actual land use of the Poverty Bay Flats located in the Gisborne district from the 2012/13 season. The survey combines six seasons of survey data from 2007/08 to 2012/2013. This report outlines the trends and observations arising from the land use survey. The survey is being carried out to provide information on the area and types of certain crops that have been grown within the region. This data will then be used to help the development of Regional Plans including a Freshwater Management Plan.

Gisborne region fish passage: Barriers to fish passage in the Gisborne region - July 2008
Department of Conservation
A comprehensive survey of the in-stream structures of the Gisborne region from the Waipaoa River catchment to Tolaga Bay was carried out between October 2007 and August 2008 to identify barriers to fish passage. The barriers caused by each structure were identified and the structures were then ranked for prioritisation of remedial work by catchment and then overall. Potential mitigation options were provided for each of the barrier types identified and guidelines provided for the installation of new structures to ensure future fish passage.
