Evaporation rate in Surin?

[Stargazer]

We have a 26 meter x 41 meter x 4 meter deep lake with about 3,400,000 liters water near Rattanaburi. I know evaporation rate depends on wind speed and temperature, but can anyone provide an approximation? We have a solar aerator in the lake that must increase evaporation some.

We can top the lake up in the dry season from our well, which currently produces about 14,000 liters a day. This is enough to raise the water level 1.3 cm per day, which may balance the evaporation. The water flow declines slowly over the dry season to about 60% of this.

We're raising Nile tilapia of two varieties, as well as big frogs and snails. We started about 6 months ago once the lake filled. So far, so good.

Mel our pond is a bit smaller than yours in surface area. Have experienced a 1-1.5m drop in level each year. We did not top it up after the first year (then only from excess rainwater from the house)

What replaced the 1-1.5m? Rain only?

That is what he said. And you should see his rainwater collection system.

@Bandersnatch, I do not think you included your rainwater collection and storage system in your blog.

Note the water tanks are on the outside of the zombie apocalypse fence, as they only drink human blood and not water.

Water

Water in all it’s forms. Water security is so significant to this project, that it deserves it’s own section. Drainage is required if your property fronts onto a public roadI felt the t…

Early on sharing my blog I got criticism about not having separate sections
