So far I did not see anyone suggesting to control the Tadpole population , not sure if the frog population will be impacted but worth a try. Froigs lay hundreds to thousands of eggs. I've heard but not tried yet that a couple of catfish will keep the tadpole population to very low numbers, maybe worth a try.....

Many thanks for your input and aquaponic suggestion, in fact we already have a proxy aquaponic system installed as the water circulating out of the goose pond routes to a gravel filled grow bed pond with Watercress and Kale and Ferns before going to the next swimming holes. This grow bed is about twice the size of the pond the gooses have purloined.
We are about to get our water tested in and below the goosie pond, I just need to work out what tests to make.

Nancy thanks for your input,

Regarding ". Is the treatment reedbed pond just before the water is dispersed, rather than a recirculating system? "


Our village is on the banks of a quite steep river valley.

Unfortunately our system is about 70% recirculating, we are blessed with a beautiful but small spring right down near the river.
This water is mixed in with the pool water and pumped uphill about 250m /30m height to the top of property. From there it flows by gravity down through it ponds and pools.
We are moving about 6m3/hr up the hill which is enough to flush everything each 24-48hrs.

So the only real option is to create a separate goosey pond and fence off the water system. As we have a spring replenishment losing some directly to an offline flushed goose pond is within the system capability.

The concensus seems to be that "sharing is not caring" when it comes to birds, humans and swimming holes.

Chris and See Hess thanks for your replies.

The pond is in in a line of pools and ponds gravity fed from the hilltop. Directly below the reedbed that is invaded by our Gooses is another 60m2 reedbed filled with gravel and plants .

This reedbed is probably acting as a biofilter at least partially.

However we have about 10 sub 10 year old sproggies playing in this water system at every level.
So I am thinking it might be a better idea to create an offline  goosie pond draining to the garden and exclude them with some fencing from the closed natural pool water system.

It's gooses cause it's 2....
Seeking advice on risk about geese in natural swimming pool
We are living in a village with 22 connected natural swimming pool and pond. The pond cleaning the water for the pools. Our latest village residents are a pair of geese. They have taken up residence in one pond, eaten everything visible from the pond and enjoying their own private heaven. The geese are grain fed by the kids and there is considerable amount of poop.
The question is about human safety for the swimmers. The same water is circulating to swimming pools that are used by our community.
Most online resources scare the swimmers with tales of deadly bacteria, parasites and so on. In the 6 months of residence the rest of the system seems to handle the load, the water is still clear and noone has died.
Should our animals be excluded from the water system???

We could as example build them a separate pond draining to the garden.
