Cow Lake; a fishing report and a fascinating case study
Cow Lake.
In it's "heyday" (late 70's or 80's depending when you fished it), it produced trout upwards of 15 pounds. Rick (or Roger?) Crozier even had a tiger beetle pattern for that lake. Fished it this past Saturday; I am mildly impressed. Rainbows averaged 3.5 pounds, not one under 3. A few pike. Which fascinates me, because I don't remember in the 40 years of fishing this province where F&W or AEP or the ACA or any whatever organization embraced the stocking of trout in a lake (slough) where there is a viable pike population. Now trout and pike co-existing is not unheard of, of course. One only needs to look at Lake Diefenbaker in Sask to see that possibility of pike-trout co-existence to the nth degree (30 pound trout). But not here in Alberta. So I am curious as to why AEP chose to dump some browns and rainbows (hey, let's get some tigers in there too!!) in Cow. And we're not talking about a few hundred brood stock either; its close to 246,000 trout in 2021 and 2022 alone (combined). AEP must think that total "bombardment flood" of trout - including some in bigger sizes - might be enough for them to establish a foothold, and so pike won't eat /get them all. Maybe; it's one of Alberta's bigger stocked trout lakes, but it ain't no Diefenbaker! From my perspective, it marks quite a significant change in fish stocking philosophy of AEP. Of course, this could be a one off experiment. ----------------------------------------- Anyways, fishing wasn't that 'fast'. 8 fish hooked, 3 to the boat. Small spoons and rapalas caught the rainbows. I caught the pike on a fly setup (the "Lauder" rig, lol). Have no idea as to the status of the brown trout or perch. I do know, that do to frequent winterkills, at one time Cow only had minnows. Then trout, then pike and perch, now both. We'll see; this will be interesting! I'd go while the getting is good. Shore anglers on Saturday - close to 30 of them - are taking their 5 trout a day limit (though most only caught a handful, but given the chance...). Don't know why...buddy said the trout tasted like mud.... Smitty |
Did you see any trout eating at the surface?

Cow Lake is a trout landfill. They got put the hatchery overages somewhere. Seems like a success. Lots of people using the lake. Far different than it was just a perch/pike fishery.
Maybe do the same stocking in Buck or Wab. I was there Monday and landed 17 pike from 3>6 lbs and 3 rainbows from 3>5 lbs. All were landed on a CDN Brown mohair leech presented on a sink tip. It was a decent day. PS: the bug life has profoundly changed after perch invaded. Dragon flies/caddies are about gone. Saw one rise Monday. Did see how fast 8” trout can go with a pike on its butt, WOW! Don |
Hey guys,
Never fished cow lake, best place to launch a boat? Are gas engines allowed? I have a small zodiac, does it get rough/windy a lot? Thank you |
246,000 in 2 years? They're just feeding pike. The few trout that manage to get big enough the pike don't bother with them anymore because they got 10's of thousands of easier to catch hatchery trout dumped in every year.
Should be some nice fat pike in and some big cannibal rainbows. Can trout spawn in there? How big were the trout they dumped in there? Seems like a lot of fish for not that big of a lake. |

Winds from the SW or SE can make the lake rough. Gas engines allowed. Some show up with 300hp. Water skiers in summer. |

Growth rate of pike and trout will be profoundly effected by perch. Both perch and pike winterkilled bad a few years ago. Food resources rebounded. Rainbows grew. Saw thousands of small perch the other day. Trout cannot spawn in the lake. |
Thanks Don.

What must be remembered, the trout stocked into Cow Lake provided trout fishing that wouldn’t have existed although the trout were available but stocked elsewhere where they all died quite quickly.
If Cow survives several winters, we may have 8 lb. Trout in the Rocky area which hasn’t existed since 2005. After pike fishing there for several years and seeing very few other fishermen, it’s great to see folks utilizing the lake. But what should never be forgotten, the jerk that stocked perch killed what was an exceptional trout fishery. Cow Lake May had provided several million of tourist dollars to the Rocky area. Don |
My wife and kids and I have had a lot of fun fishing there this year. Too bad there is little interest in aeration around here. Not much depth so I can see how it’s pretty easy to winter kill lakes like this one. When I lived in central BC we had plenty of smaller fisheries aerated to protect them

There is quite a number of lakes aerated in the area. These include Mitchell, Birch, Ironside, Fiesta, Beaver, Hanson’s Pond which are aerated by the ACA. Not sure who is aerating Alford Lake presently. While there are several others that could be aerated it takes those interested to put the project together. Ironside was done by myself and Warren T. The process took two years involving fund raising, presentations, management of construction, construction and on and on. Several of hundreds of hours of volunteer efforts and a $50,000 cost. Once the facility was constructed and fine tuned the project was taken over by the ACA. As a preamble to the Ironside Project, Warren and IDed a number of lakes that could be done. That took both a winter and summer component. Don |

Hey guys,
Another question, is cow lake really only 6 to 7 feet deep? Seems pretty shallow |
Quote:
A good thing where sunlight gets to the vegetation in mid-February which produces oxygen thereby assisting in fish survival. A good thing as no part of the lake doesn’t produce food as all of it is subjected by sunlight, A good thing as when vehicles fall through the ice, recovery is easier. A good thing where wind stirs the lake completely keeping O2 levels high in the summer. A good thing from a fish catching perspective as the bait, lure or fly is only 7 feet away whereas 20’ lakes, the distance is much higher. A bad thing ………………? Don |
Bad thing is that there's no boating speed restriction,or powered motor .Sea-doos & 300hp boats have no place being . IMO

I’ve never encountered a safety issue with the large boats. They generally give me well over 200 yards. Their 5000 watts of lousy music however tends to ruin the day. Don |
Hey Guys,
I fished cow last evening for a couple of hours. Water clarity was pretty low, about a foot. Not sure if that is normal for this lake? Hooked a nice fish on a leech pattern, lost it at the boat. Thanks for the tips, hopefully I will get back before it freezes. |
The score for September 7+17+4= 28 pike, 1+3+7 = 11 rainbows.
And interesting fishery as most of the fish were caught on the same fly. Don |
Kinda makes me wonder if that's all the fish have to eat.Years ago it was a shrimp lake.Perch eat all of them,minnows to i guess.

Years ago it was dragon fly nymphs and sticklebacks. Don |

* no, of course trout cannot spawn; it's a glorified slough * check the stocking lists; sizes varied * Relatively speaking - for an Alberta put and take stocked trout lake - it is one of the biggest lakes in the province. Again, I am speaking relatively, when compared to other waterbodies that trout are stocked in. Quote:
Ideally, you'd have a lake that would totally winterkill, zero pike, zero perch, restock with trout, spend the $$$$ to aerate. But mother nature and our bucket bios have other ideas... Quote:

Do the pike
Still have tumours on their bodies?

Mind you, several years ago I was catching several hundred pike and only got one infected. Don |
