Trout Fishing in Lakes

Folks,

I need some hope from your wisdom!

I line in New Jersey and have enjoyed salt water fishing on those
organized party boats.
Lately I got into fresh water fishing at Round Valley Reservoir in
Clinton. This man made lake is second largest in New Jersey and is
supposedly stocked with all kinds of trout.

I have read many many articles on the web and magazines about trout
fishing. Most of these articles are very weak on the type bait used
and the how deep you should go to fish. I have tried the following
recommendations:
a. Plastic lures (Various kinds) with a small sinker to go deep 30-40
feet: Did not work. Not even a bite
b. Salmon eggs: They work but the fish are too smart. Besides the
eggs easily fall off the hook.
c. Earth worms: No bite. Did not know what depth I should go.
d. Minnows: No bite. Did not know what depth I should go.
f. Trout bait - Shiny yellow modeling clay type material. Lot of
bites but the bait falls off.

So, fellows, please put me out my misery and tell me the secret ot
fresh water trout fishing!

PLEASE!!!!
