Brook trout fishing tips

hello everyone I am Marcus and new to the forum, I have a few questions to ask about brook trout fishing at a local lake near my house. The ice has been out for roughly two weeks now at the local lake and ive tried numerous times for some ice out brooks ( catch n release ofc), with practically zero luck at all, ive throw blue foxes, to jerkabits and no bites at all. The water tempatuere is just about 50F on the shore and this was yesterday I checked, with this week being really warm will defiantly help warm it up. So, does anyone have any tips like what depth to fish, more lures to fish, and why am I struggling so much to get some trout, even through ice out is supposed to be very good? last year I was hammering them towards the mid may year but last years weather was much colder than this years at least so far. if you have any tips on baits, water depth and structure to fish, and water temperature please respond as I am open to anything, im just very puzzled on why im not getting any a action from fish latletly, and do you think with the weeks worth of 15-20c weather will help me? thanks Marcus.

I have limited experience with lake brook trout but in big bodies of water (Lake Superior, Lake Nipigon, etc) they tend to relate to shoreline structure. This is a primary reason why they are referred to as “coasters”. Ice out is definitely advantageous for lake trout as they can be anywhere and can be caught in the top of the water column. I don’t know how well that translates to brook trout as they don’t seem to use deep water. The few I’ve caught in lake situations have always been in relatively shallow water (shorelines, shallow rock piles, etc).
