Hi my question is do I have to worry about stocked fish swimming downstream and over the spillway that is the ponds outlet. In the spring the water really flows through there then in the dryer part of the year considerably less. My species of main concern are walleye LMB, BG, perch, and Crappie I am also considering placing a lone musky in pond.

Pond profile is a 45 year old man made {inlet-outlet} previously subject to winterkill and otters. both are being dealt with. Although the water is not muddy it is a blackish brownish,,almost like a dark iced tea color... how would this affect the fish?
5 acres
15+ foot holes
5-9 foot in middle
sand and muck bottom
boulder levee wall

I guess I have quite a few questions and would appreciate advice especially if anyone is familiar with what I have mentioned or if you are familiar with northern ponds
