ah yes, heart lake, i worked their for 3 years and have caught bass several over 6lbs easily and have seen bass wash up dead close to 8lbs+ when i use to pick-up the goose shit from the beach, LOL
i wonder if kyle drake is still the manager their, i taught him everytrhing he needed to know about running parks ect. before i left to go to the government to do invasive species removals and inspections and teach at seminars ect., man that was over 10 years ago, but the fish get muddy tasting in the fall and don't swim in the water, they rack the goose shit right in the beach now and water ,and people get wicked rashes in the summer from it from the bacteria their!!!!!! and they would come to park seeing wher they got the rash from???
guys use berkley power bait (green and blue!!!! paste)and u can't fish off the dock, but the north west side is the best, the same side of the docks just north abit, cast as far out as u can and let it sit their, and if u see it move, set the hook!!!!!
and for the BIG BASS, i saw this asian fellow, visiting here from asia, he rented an boat, and i told him to go fish under the pontunes where the water airates the lake,and it is the deepest spot in the lake their and their all under their!!!!!!, he caught and took home 2 large mouth bass well over 6lbs, i would say 1 was around 8lbs, that was before anyone fished their hard core and no one ever caught anything, i should know i rented the boat for 2 out of the 3 years i worked their, my knees use to blled from working so hard renting boats all day, i would make i one day well over 800 buck just renting boats!!!!, but i could go out fishing durring the slow days i worked their, and catch my limit in bass and rainbows in 3 hrs drifting around, ah good times!!!!!
more bass are on the right side of the lake and the back right corner is an huge weedmatt (stay away in the summer time please, i hated pulling poeple out with the motor boat), and along the back of the lake is good for bass too under the trees at high noon, and in the morning, the trout coming right up to the beach on the south end!!!!!
and mr. patterson, use to grow the fish all himself at glenn haffy conservation on airport road and hwy 9, and he took great pride on the food he used, cause he knew by late summer the fish would taste like mud! and they use to put an mix of big one's and small one's, but who knows what their doing today their?
they have secruity their at night now and i use to bring my boat and trailer on quiter day's and bring my trolling motor and motor around all day, and just hammer them, ah good times, but i haven't been their since i left!!!
nice to see things are still the same! and doing well! but might not be after this post, but with all the pressure and non serious fisher people in their, i surprised their are still fish in their!
and a little story for u guys who fish the lake, heart lake came under the management of toronto region conservation athourity, is the famer and his only daughter years and years ago, use to go on the lake every winter, all winter, and used horse and sled to bring manure out on it, to dump on the ice in the deep hole spot as mentioned by wisemanTO , but one year the horse and sled and farmer and daughter went through the ice and all died and the wife gave the land to the athourity to manage years ago, and if u fish off bottom their in the deep hole, u will get snagged on something, and old art downey who worked their for over 30 years and maybe more he said it the old sleigh down their your hooking up on, cause no one ever took it out(nasty) and the road u drive in to the beach parking, is where the old river use to come into the lake where the beach is, so the blocked it off. and that's why in the morning in the summer it is an good place to fish for big bass and trout!!!!
and no catcherman it is all keep!!!!!! and enjoy, just like the way TRCA likes it ( put and take conservation), their mado is " profit first, conservation second!!!" that's why i left, i and may others did too, we all didn't see eye to eye to several new commers to the athourity with their big degrees, but couldn't tell the diff. from and tree to shrub or an minnow to an fish(SAD!)
TRCA clorinate their water in albion hills where everyone swims and the huge algea blooms floataround so bad u can't even swim or fish, and it is where i worked for many years too, and in the fall time they blow out the river and drain it all into the humber river and any stocked rainbows left that weren't caught go down river to be preyed opon anything!!!!
now before everyone get's hyper for big trout, they only stock like tops 20-30 or less rainbows in the park and they are not good eating(taste like mud) and are just their for fun, i have caught them before with my G.F. now wife and she can believe she fished their with me well over 10yrs ago!!!!.
man i better get fishing today, and less writing, people are finding all my old spots, they were amazing back in the day, and seems like their doing well still today!
but i'm fishing my northern spots, now, i grew up as an young boy learning to fish, and their still amazing to this day!!!
hope i gave evrryone the answers they were looking for

and everyone enjoys fishing their, the same i did a long long time ago, and keep it the same for many years to come!!
