Hi OUTHNTN,
What area of LML were you thinking of fishing?
Will you be shore fishing or using a boat?
LML is a place where a person could potentially catch some large pike and walleye as well as other fish species. They are definitely there.
The last few times I shore fished at LML, I had good luck on swimbaits like the storm wildeye swimshad, Berkley flatback shad or similar style and a spoon like Len Thompson spoon, Daredevil spoon, Pelican lures fishing spoon or Northland's Live forage casting spoon.
Brighter colors seemed to be the ticket for both spoons and swimbaits as the water can get a bit merky with algal bloom in summer.
As for other rigs, I know folks also have good luck pulling bottom bouncers and spinner rigs with worms, leeches or frozen minnows while some have good luck on deeper diving crankbaits.
If you had a not picked an area of the the lake yet I might try fishing around the Rowan's Ravine / Fox Point area.
Those 2 ares of the lake is the deepest and the points should hold some fish.
Not exactly sure what depth but if you have a fish finder with you will see them.
These fish sometimes suspend in the water column as they hunt the ciscos / tullibee's both the pike's and walleyes major food source.
Rowan's Ravine area is a Provincial Park so you will have to pay to get in but it's a place that has a lot of services + guides at G & S Marina.

http://www.gsmarina.com/The big carp that LML has is another fun bruiser to fish for. Most of them are a good size, 15 - 20 lbs with a few 30 lbs and over.
The biggest carp I have heard come out of LML was 50 lbs, but it was shot with a bow and arrow.
Even if you all ready have a spot picked out it would be a good idea to contact Rob from G & S Marina or the folks at Pokeys tackle shop or Great Northern Rod and Reel.
Both tackle shops are in Regina SK and both usually keep track of where the fish are biting at LML and other lakes.
The number for G & S is on the web page.
Pokeys website has his number on it ------>
pokeystackle.ca/It also has a fishing report on his web page, but it don't go into detail on what the hot lure or depth is.
Great Northern Rod and Reel's # is: (306) 359-7378
Both are good places to stop if your passing through Regina.
Here is a link for you to a depth map for LML. Just click on this link --->
http://gisweb1.serm.gov.sk.ca/imf/imf.jsp?site=bathy Once your on it click on the finding a lake area to the right of the screen and search to you see LML listed.
You then click on the star and see several depth maps for LML.
I hope I have helped you a bit.
Good luck with your trip and I hope you and your family catch some big ones.
P.S. Most folks in SK call a walleye a pickerel, so if you hear the locals talking about pickerel you will know what they mean.
We don't have any real pickerel here in SK.
