Bay of Plenty Regional Council has reminded rural communities to keep grazing stock off stopbanks as winter sets in, so the structures can fully achieve their intended purpose.
Stopbanks provide essential flood protection for thousands of people in the Bay of Plenty and, while they can be grazed by cattle at some times of the year, especially when the ground is firm in summer, grazing should be kept to a minimum in winter.
Wetter soil conditions, combined with heavy animals, can weaken and damage the region's stopbanks, Council Principal Works Engineer Tony Dunlop said.
"During winter it is common sense to keep cattle off the stopbanks as much as possible to prevent the pugging and damage they can cause. Most farmers and lifestyle block owners know this and take care of our community assets.
"Good grass cover on a stopbank helps protect the soil structure underneath, so pugging is not just a surface problem," Tony says. "It can cause much greater issues; one weak area can have a disastrous effect on surrounding properties and stopbanks. All it takes is one breached section of stopbank to flood thousands of hectares of farmland."
