We also are looking to fish this weekend.According to my IWindurf forcast,looks like south winds to 20mph on friday and Sunday.Wind forcast looks fishable Saturday,but weather forcast has 80% chance storms Saturday.So may be difficult to find a window to fish.
There is an occasional group text on this site that could help you find some active fish if you join the group.Since coming out of East Harbor,a good place to start,and close by is American Eagle Shoal.I have seen alot of people casting in that area,at this time of year in the past.
As for how to cast,I came across a well writen and thorough article on how to cast for walleye on lake Erie.Go to Coe Vanna Charters website.Look under fishing reports and scroll down to lake erie fishing techniques and lake erie news.Some great info on casting and the news articles talk about the different class hatches too.Good luck.
