Found this online..... a few neighbors were discussing ways to reduce the weeds in the pond with Carp. Thought this would be some valuable info.

Perhaps the most effective biological control for aquatic vegetation of fish ponds is stocking grass carp (or white amur). This fish is native to large rivers of Eastern Asia and was brought to the United States in 1963. It has been proven effective for controlling most kinds of submerged vegetation found in Oklahoma ponds.
For general weed control, stock 10 grass carp per vegetated acre. For heavy infestations, 20 fish per acre may be required to obtain effective control. The fish should be at least eight inches long when stocked to minimize predation by adult bass. Grass carp generally will not provide effective control until they reach approximately three pounds. Therefore, a noticeable reduction in the amount of vegetation should not be expected until the year after stocking. If, after three years, satisfactory control is not achieved, more fish need to be added. Grass carp will not reproduce in ponds. Therefore, periodic restocking (every four to five years) may be necessary to compensate for natural mortality.
Grass carp are available only from private commercial fish producers. A list of fish producers is available from the Department of Wildlife Conservation.

Grass Carp

Thank you for this information. I have had 2 conversations with neighbors in reference to this. A gentleman has sent off an application along with the fee to the Wildlife Conservation. Once he gets it approved, they will let us know how many need to go into each lake. At that time we should know how much they are and the neighbors that I have talked to will put in money to fund the purchase of the Carp. I know that 3 people on the large lake and 1 on the small has agreed. Hopefully this information will help.

Carp

This is a good idea, but one thing you all need to think about. When these carp eat all the grass you will lose fish. The reason is, they will have nothing to lay eggs and bed up for spawning. Therefore we would have to catch the carp and remove them. We will still need aerators.

Carp/ Aerators

That is a good point, however this is why we are getting with Wildlife Conservation. They will only allow us to purchase so many carp to rid the lake of algae. The number will depend on the size of the lake. I will verify this before any carp are purchased by the lake lot owners. Also, this has to be reviewed by the New Board and approved.

As for the aerators, along with the culverts being blocked to keep the water level a bit higher,this is definitely something that needs happen.
