how do YOU check your catchment tank water level?

[terracore]

My catchment tank cover is a PITA to loosen so that I can look inside. I had been checking the level by feeling the tank sides in the afternoon. The steel was warm above the water line and cool under. Now that the level is lower, that technique doesn't seem to work as well.

I use a one inch clear food grade hose ,,,I lay one end securely next to the foot valve and then draped the hose over the tank wall and all the way to the ground , then back up to the top of the tank ! ( the Egyptians were pretty smart guys )then I take water and fill the clear hose completely ,,,, once done you only have to look at the clear hose outside to see the level of the water on the inside . Egyptians wow and it works like a charm

I lightly rap the side of my corrugated steel tank with my knuckles, working upwards. Where the tone changes, there is your water line, more or less. You have to listen carefully.

I use a 4 foot wooden yardstick

I get out my foldable 6' wood ladder and climb up and peel back the black shade cloth stuff from under the ropes holding it on and poke my head in and look. Good to do this because you can not only check your water level but check what else is going on in there. Such as unwanted critters etc.

We put a float inside, line and sinker along outside and can read the approximate level.

the thumping method works well for us until we are well below a quarter of a tank, that is usually when we order water and it starts to rain.

And it looks like the rain forecast for this weekend for most of the Hawaiian Islands won't make it to the Big Island. Looks like at least another week or two before we get some appreciable precipitation.

You may want to add a back up second tank of 12,000 to 16,000 gallons so you will not have these issues in the next prolonged dry stretch.
Till that time though,all the methods mentioned here seem like good options.
It will probably start to rain again mid march or for sure Merrie Monarch time / Easter .
