Pictured on Sunday morning this week... Green weed on the Old River Ancholme in Brigg - either side of the County Bridge. Fortunately, they now carry out periodic cuts to reduce the clogging of the waterway. This helps stop litter accumulating in the weed and also helps craft using the river for leisure purposes.

One of the main culprits of extraordinary weed growth is nutrients, often the result of agricultural fertilizer run-off entering the water courses.....combined with warm weather and summer sunshine...it feeds the river weeds.
The Ancholme is a slow-flowing river, so any abnormal nutrients is not readily dispersed...
Cutting back the weed growth is a reactionary control method.....perhaps a better method would be to have sediment ponds on farmland where fertilizer run-off is allowed to collect before it enters the main water courses.
This proactive control has at least two benefits - farmers can pump-out these sediment ponds back onto the farmland, thus saving agricultural fertilizer costs by recycling ..and the main water courses would have less abnormal loads of nutrients consequently ameliorating river weed growth in the warmer months.

....and if you do it twice....it has a double effect!!!
