Hey guys so I want to get out of only fishing what I can see above water. I have been doing some reading and I understand idling over humps and all to find a sweetspot to throw to. However I need some advice on how to start on my local lake. My problem is that there are no topo maps available for the lake I fish. So I cant really try to find structure from a map and then apply it on the lake. To give you an idea about hte lake, it is a reservoir, and I have seen water up to around 50 feet deep. However I have never caught fish, or heard of anyone else catching fish any deeper than around 20ft. Most of my summer fish last year coming off of 5xd's so around the 15ft range. The deeper water fish that I did catch were just from backing off the bank and still throwing in that direction, so I was not really using my electronics to target underwater cover. 

 

So without a map to find structure, how would you go about fishing deep for largemouth? I was thinking just idle in the 10-20ft range until I find something that looks good on a point or just going down the bank until I see something, but that seems like it could take up quite a bit of time. Is there a more efficient way to go about it?

The topic is already running 5 pages. Look down a couple of lines.

I reposted your question in that thread.
