The Northampton Branch of the IWA adopted the Arm 2 years ago, I've recently been co-opted onto the committee after attending many work parties and making various 'suggestions'!
We have persuaded CRT to bring forward the work that needed doing on the Arm for the Northampton Festival of Water this August, most of the work has been done, ie reed cutting, offside vegetation, but the areas that needed 'deep reed cutting' (or dredging the roots out) has been put off until later in the year. They have assured us it will be done before the Festival, and believe me, we will keep reminding them!
