Note : 5th November 2020 : Pollution incident. There was a spillage of oil into Rodden Brook, one of the tributaries of the Somerset River Frome. Response from Sue Everett of the Friends of the River Frome who writes: “No reports of any impact to fish or macro-invertebrates since this sort of pollution sits on the surface, which is a good thing. They are using bunds to contain it and pads to soak it up where possible, but it does spread over quite a distance so soaking it all up is not possible”.

Ms Everett was made aware that a similar incident in another part of the country showing no initial impace but had a quite severe impact after several day and pass this comment to the Environment Agency who were monitoring the problem.

Note: 24th August 2020 : An investigation has begun after 100 fish were found dead after the river turned black following a slurry spill. The 0.6 mile (1 km) stretch was along the East Woodlands tributary of the Somerset River Frome, near Edmund Park in Frome. The slurry spill in spring 2016 was by a farmer in West Woodlands.

Note :  19th December 2018 :    The Environmental Agency have today released 6,300 fish into the Somerset River Frome (including 2,000 roach, 1,500 chub, 1,000 bream, 600 tench, 600 crucians [carp] and 600 dace).  The restocking is part of an annual programme, funded by rod licence sales.  Restocking occurs in winter because water temperatures are low which minimises any stress on the fish, giving them the best possible survival rates.  Restocking is done where numbers are low or have been depleted following a pollution incident, as happened in Frome in Spring 2016.  This is good news for the Frome Angling Association and our local Otters!

Note :  10th August 2016 :  The Environment Agency’s survey of the River Frome’s fish stocks has been carried out (three months after the Category 1 pollution incident upriver at West Woodlands) and showed a lower than expected number of fish in the river running through the Farm, (mostly roach, a few pike, common bream and dace) although they caught 1 eel and 1 lamprey.

Given the numbers of Herons, Little Egrets, Cormorants and Kingfishers roosting and possibly breeding along this stretch of the river as well as the regular Otter spraint it would appear that there is again (summer 2018) an abundant and varied fish stock, which we hope the next survey due in 2019 will confirm.

Note – 12th May 2016 :   
1,604 dead fish, including Roach, Chub, Dace, Trout, Perch, Gudgeon, Bream and Pike,  Bullhead, Minnow, Stoneloach, Sticklebacks, were recovered from the River by the Environmental Agency following the spillage of slurry from a farm in spring 2016. 

A typical water meadow carries a mixture of finer grasses and herbs including ^Timothy, sweet vernal-grass, crested dog’s-tail, ^meadow fescue, ^red clover, ^sorrel, ^meadow vetchling, ragged robin, ^ribwort plantain, ^meadow buttercup as well as ^lady’s smock, ^marsh marigold and ^bugle.

^ All widespread along this stretch of the River Frome .
