Our 1st dam which acts as a silt catcher for the Big Dam always gets covered with a Red Duckweed which is a great water filter and keeps the water cool and clean and flows into Dam 2 ( the Big Dam)

This great water plant is" fantastic free nutritional mulch" for our gardens and as soon as we harvest as much as possible it grows at a "rapid rate" and covers the top again.

Who else "harvests" their Duckweed?

Harvest is fun as we swim the surface holding a 5mtr Bamboo culm which floats on top and pushes the "great mulch" to where we steer it..will take pics on 1 of our "harvest days" :)

The Raphia in background is 1 of our 3 sizeable Australis. Pete :)

Thanks Michael, and thats our "smallest' Australis :) the royals love it too.

From reading about Duckweed, its consumed a "Lot" in Thailand and is very high in protein, glad we have it in the 1st dam, its great stuff.

Well, first I'd have to have a pond, right? :mrlooney: So how much water do you manage to hold in your dams? Does it last you through a full dry season? And it's purely for irrigation?

There is a 10,000 gallon catchment tank on my property, but the water being solely for use in the home, I won't be growing duckweed in it. B) Too bad, such a great renewable resource!

That looks like Azolla, a nitrogen fixing aquatic fern. Are there any fish in your dams?

Kim, our dams are supplied by the flow of "constant running water" so they "never " go dry, the spillway has water running over it "all year. :) small dam covers some 800 sq mtrs and the Big dam which is used soley for garden water and swimming covers a good 3000 sqmtrs.

Xenon, yes it is Azolia and yes we have "silver perch" a native freshwater fish in both dams. Both dams have the native freshwater tortoise , ducks and 2 resident Platyus. :) Pete
