Request for advice on de-silting.

[DonRamos]

My club has a 1 1/2 acre lake with what we believe is 3 foot of leaves and general sediment on the bottom of it. This build up has not been dealt with for a considerable period of time and has resulted in a reduction of the depth of the lake to less that one foot in places. Last summer a large number of carp died at the venue due to low oxygen levels caused trough the lack of depth and the large covering of duckweed that the lake has. Does anybody know of a relatively cheap method of removing the leaves and sediment from the bottom of the lake? We can get together a group of people to do the work but we do not have the funds to dredge the lake. The duckweed problem is in hand but any responses to the depth problem wold be greatfully received.

Siltex is indeed a good product but in reality probably wont give you any more than another foot of depth, if done properly. IMO the only real solution is to drain and get machines in. This will cost a bit in the short term but is the best long term solution. Machines are not that expensive to hire, what costs is the labour. So look to hire (or borrow from a friendly farmer) and do the work yourselves. Getting rid of the spoil can be expensive if it can't be used / dumped on site, however it will be rich in nitrates and useful for farmers to spread on their land.

Alan your dam right it can be expensive! Having it removed to a landfill site will cost you trucking fees, landfill disposal fees, and lanfill tax. Possibly as high as £100 per ton, dependant on how its classified.

 

You mentioned its NPK value. As a natural fertilizer mixed with other organic farm waste it as high as you could get.

Why do think that the most productive growing land is on the floodplains of rivers?

 

Silt my man, silt!!!!

 

I would think that such silt is a very salable material indeed, to organic growers and farmers.

 

Soil Association may be able to give people information on prospective buyers

I`m going through this myself but on a much larger scale. We are tipping locally so it is a piece of cake. Money can be made avaliable to you for enviromental projects such as the desiltation of lakes through `The Landfill Tax Credit Scheme` if; You are within 12 miles of a landfill site and you draft members of your club from the public domain. 100 per cent grants avaliable. Have you got a good secretary Donramos?
