What time can i start fishing ? And how much per day please? Is there consetions for oap dissable thank you

Hi there, I work with young people of school age on engagement. I am looking into obtaining some basic (starter) equipment with a view to taking students fishing at a place known as Wombwell Dam, nr Barnsley, South Yorkshire. I have never fished but would be taking students who have and have an interest in it, likely to be one student at a time. I am aware there will be cost implications, day tickets/year tickets, permit to obtain, but unsure as to exactly what I will need. Any information, guidance would be greatly appreciated. Thanks in anticipation, Martin
