Waikato Regional Council monitors river levels and rainfall in the Waikato region to help predict floods, minimising threats to human life and property. We monitor river flows to ensure water takes don’t exceed acceptable levels of use. Changes in river flow over time help tell us how often a river floods, how it responds to extended dry periods and how much water is available for human use and natural habitat.
We all rely on the region’s freshwater resources for:
But in times of flood there is too much water and in extended dry periods there can be not enough water available (low flows).
We need to monitor how much water is taken from our streams and rivers so that:
Wetlands play an important role in our water landscape as storage areas for floodwaters and have many plants and animals that have adapted to live in these conditions. Wetlands slow the flow of water off the land, soaking up excess flood water, and then slowly releasing water to maintain summer flows. Waikato Regional Council monitors river flows to see how they respond to extended dry periods and how much water is available for human use while maintaining natural habitat.
Waikato Regional Council also monitors river levels to reduce the risks from flooding in the region. Flooding is a risk in the Waikato region because frequent heavy rain and the steep gradient of many rivers mean the region is prone to flooding from severe weather patterns, especially tropical cyclones and depressions.
In the last 25 years many floods have been recorded, affecting urban and rural communities.
Waikato Regional Council's electronic monitoring of river levels and rainfall in the region provides early warning to the region’s population of potential flood events. We monitor water level, flow and rainfall at over 80 water monitoring stations.
