Thousands of fish have died and thousands more are at risk after Tuesday's storm tides sent seawater flooding into our rivers.
Environment officials are working to calculate the damage done to the sensitive Broads system in Norfolk and Suffolk
It's estimated around 25,000 fish died as a result of Tuesdays storm, the majority of those, about 20,000 in one dyke at Acle.
Strong winds and high tides led to some serious flooding witnessed by holidaymakers
The Salt water incursion killed the freshwater fish.
Fish specialists at the Environment Agency have been on the River Thurne in Norfolk monitoring the current levels of seawater and checking fish stocks.
Angling is worth around a hundred million pounds to the local economy.
The Environment Agency are also checking a boatyard in Potter Heigham.
Sonar equipment on their boat gives them an accurate assessment of what's underneath.
