From the wv fishing regs- It is illegal to fish with more than two (2 ) lines or poles in an impoundment stocked with trout by the DNR from January 1st- May -31st......
To simplify,any trout stocked pond, lake or reservoir,can only be fished with two lines/ poles from January through May, After May you can fish with all the rods you can handle. Waters not stocked with trout do not have a rod/ line limit.I hope this clears it up for you.
