"Nutrient rich" i.e fertilisers, slurry run off.

How’s that get into our local lake though ? 
 

lakes rich in natural nutrients?

Bad that mate never seen it like that has the water level dropped and that just silt ?? 

Never really much change in levels on the lough as its controlled by locks on the river bann on its Northern shore, it'll rise in the winter at this end with plenty of rain and a southerly wind, it's 33 mile long so a big old lump of water. 

That photo is pure algae pushed against the banks by the wind, waters 3 or 4 feet deep there.

You would think that opening locks would flush it out.

I'm sure it's not that simple though that's a huge amount of water to play with.

Any luck it will start to disappear soon.

Well, obviously over use of fertilisers means excess will end up in drains, then rivers, and finally into lake. I watched a vid this morning about the same problem on lake Erie in USA. They said fertilisers and slurry had a big part to play in it.

We get it on the River Wye when it goes real low... normally fucks off when we get some rain and the levels rise again..

Local lake suffers as well...they use bales of barley straw in the margins when its at its worse

Would need a shit load of lorries full ,to sort out an expanse of water 30 miles long

Algae blooms are natural phenomenon, when silt decays it releases Ammonia, The algae is natures way of stopping this Ammonia from killing the pond/lake/sea or what ever. When Ammonia is produced, Micro organism's feed on it including algae. these organism's then die off and Nitrite is produced as they decompose. This Nitrite is then eaten by other organism's, When these die off Nitrate is produced, This Nitrate is then consumed by yet more organism's, When they die off Nitrogen is produced, Nitrogen is a fertiliser. As it gathers on the bed of the the water it fuels new weed growth. This is the cycle of Algae and is perfectly natural in a heathy  lake/pond or what ever. 

Fertiliser run in will effect this cycle.
