I personally know that area very well. Have helped develop Richmond Mill Lake of the King Fisher Society.
You have two important things to do BEFORE buying any fish.
First, do the electrofishing survey. If you'd like to have a conversation about this and help develop a plan, I can be available by phone most of the day Thursday. PM me if you are interested.
Secondly, develop a habitat improvement plan based on your goals. Use your topo map to start that process to determine placement. Learning aquatic plants is a smart idea...seeing what you have is wise.
Then, with solid data from an electrofishing survey, you can create a stocking plan that fits with your management plan and budget.
Happy to help develop that with you and refer great vendors for your plan.
