Walleyes at Lake Powell

Seems like we need some graduate student to study the walleye in LP and get some scientific knowledge about their diet and life history and not just a bunch of internet speculators (I include myself a member of this group)!

Actually -- we don't. We already have Wayne and DWR Dan.

The simple fact is: lowering the walleye population WILL increase their average size. Same with smallmouth bass. No matter how much that pulls on the heartstrings of many of you, that is the truth. That's why the limits are the way they are. There is no other explanation on why we have NO LIMIT on walleye at LP.


For those asking to save the "big" fish from harvest -- what does that gain? In a healthy system, ALL fish are growing quickly, and thus any "big" fish removed will quickly be replaced by another fish. Small fish also reproduce, so removing "big" fish doesn't impact recruitment. The "big" fish isn't a product of "big genes", they are a product of their environment.

the walleye, stripers, smb all top out (on average) at sizes that are less than desired by anglers due to population. Population densities have all of those fish in a growth zone that is NOT optimal (ie: FAST). In order to get the fish populations into the zone of maximum growth, you MUST reduce the population. All of them -- including the "big" fish.


Like I said in the previous post -- it's all about education. No matter what your passionate opinion might be.


From the report Wayne posted:

"Increased promotion of the fishery is paramount in the face of uncertainty over the effects that Quagga mussels may have on the Lake Powell fish assemblage as well as the effects of warming water temperatures. Removing the creel limits on Walleye was a positive first step. Promoting the Walleye fishery through media coverage and fishing contests is also vital in allowing UDWR to structure the fishery and keep it healthy and producing well into the future."

ie: harvest walleye.
 
From page 110 of Wayne's report:
Larger Walleye would be more desirable from an angler stand point and hopefully the management goal of increasing harvest will allow for improved growth
 
All I know is a 3 pound smallmouth stops growing when it’s sides are cut off….

but, if growth rates were in the maximum rate zone, then it would be replaced by two, three, or four 3lb smb almost immediately!

It has been said a bunch: It takes many years for walleye and smallmouth to reach trophy size. Why? Why does it take so long? The answer is because growth rates are SLOW. Why is that? Because the population density is too high! (top area of graph below) Reduce the population density and growth rates increase( middle maximum growth in graph below), which will decrease the amount of time it takes for those fish to reach trophy size. Instead of taking 6, 7, or 8 years to grow to 20", you could do it in 3!

We know that at Lake Powell we are not in the bottom zone (overharvested) because fish are reaching sexual maturity and spawning at less than desired sizes. If overharvest was a problem, we wouldn't see this. The slow growth rates that you all have expressed concerns over are due to underharvest.

It isn't rocket science.

We want to be in the middle zone: maximum growth
We don't want to be at either end of the spectrum where growth rates slow: overharvested or underharvested

I hear you although I don't think that is a factor on the larger walleye. There's not allot of 4 pounders being caught and kept and an even bigger factor I believe is the overall catch rates for walleye drastically drop outside of the Apr, May, June timeframe.
I don't fish Powell much outside of the spring, but I have heard this on WW. We tried once at the end of September, and the surface water temperature was still around 80 degrees in the afternoon. I would hazard to guess that they are deeper than most folks are fishing during the day after June, effectively making them off limits for anglers.

Sounds like folks really can hammer them in the fall, I may have to make that a goal for post-retirement activities! What Fall time frame is usually best to target Walleye?

Walleye metabolism and activity are at their peak with water temps 60-70 deg so whenever the water temps get down below 70 deg for the daytime peak in the fall. They slow down in Dec, Jan, Feb. There's been posts on here in years past of people finding schools of the deep while looking for stripers. In the hot part of the summer tune your finder until you can see the thermocline and they will be right around that depth, often just under it.
 
I have fished lake McConaughy and it's a great lake but I don't think the water temp there get's near as high as it does at Powell at peak and the thermocline probably not near as deep.
You are correct. The highest surface water temp that I saw last year was 78* That temp was that high for only a week as the following weeks the temps dropped. Previous years the temps did not reach 75, last year was different due to little runoff and the lake dropping to it's lowest level in 10+ years. Less water = warmer water temps.

Thermocline is strange at Mac as the water there is removed from the bottom and I am not certain that a thermocline truly develops. I see fish as deep as 70 ft I don't spend time looking for fish in the parts of Mac that are deeper than 70'
 
If I catch a 10 pound walleye or a 6lb smallie this year at Lake Powell. After weighing measuring and photos they will still be swimming next year. ;). Pic of 5.25 smallie last weekend at Lake Mohave. Still swimmin. And limits of eater smallies and walleyes won't.

crappie are doing better than most think the trick is to finding them.
I agree on the Crappie and after the newly flooded brush and other shoreline vegetation we should see this runoff season it will provide better spawn conditions and nursery for LMB and Crappie. We should see a nice improvement in quality and qty for both! In the next few years!! Let’s hope that Lake Powell rises a bunch and floods a lot of cover and stays high enough to cover it for next years spawn too. It will be great for the fishery!
Let it snow!!

One other thing to think about that could affect catching of larger Walleye at Powell are habits and the habitat or zone they thrive in. Large Walleye in powell may prefer deeper water, colder temps, maybe venture out alone and not stay in schools. They may also target larger prey and not feed as often , for example?
Maybe there are more big ones there but nobody has figured out how to catch them consistently?
Most, but not all of the big trophy walleyes at the other lake I mentioned in earlier post, no secret (starvation res. Ut) are caught by the few anglers that target them specifically. “Most”/Many of the guys that target them, like to fish with much larger lures than most anglers would use and also fish at night or very early am to catch many of the larger ones. They catch fewer than others but they catch a lot of the trophies !
One angler I knew that caught dozens of these monsters up to 15 lbs.
He liked to fish very specific nights of the season and certain techniques to focus on the bigger walleyes, he loved big 6” plus swim baits and larger “rapala” type lures. He fished a lot from 10 PM to first light. His favorite months to target the big ones but not to exclusion were August September and October . (Loved bright moon too)
Then with that said a buddy of mine got a 7lb walleye when I was fishing with him at starvation one trip at 2 pm in the middle of the day on a 95 degree day in July in 2 feet of water on a 3 inch grub when we were fishing for smallmouth so go figure!
One early powell trip many years ago we thought we were going to figure out the walleye at Powell
Back then we Launched at Hite and we were fishing the Colorado river arm under the bridge.
We decided to try and mark fish with the fish finder on ledges and try vertical spooning for what we hoped would be walleye.
I got a hit very shortly after starting at about 45 feet depth and I landed a nice healthy, about 6 lb Walleye. Boy are we good!! I thought !! We figured them out!
Well it was the only Walleye we got for 3 days on the 4th day we were trolling crank baits 50 feet down on downriggers getting stripers over river channel in deep water suspended and we get a 4lb Walleye the only other walleye we caught! One other interesting thing from that trip is we marked some fish on a ledge 60 feet down. I vertical spooned with a 3/4 oz Kastmaster caught about a 1 lb crappie!! (Often wondered where the Crappie disappear to for parts of the year, maybe they just move deep to cooler water and hang out) Tried for another 30 minutes to get more crappie nothing!! We did get a few nice bass that trip . We used to catch a ton of LMB Vertical spooning back in the 80,s in early season March April.
(That will date me)
More food for thought! Great thread!!

The wife and I catch our share. Mostly trolling crankbaits. Most of them being Flicker shads. The key for us is to keep the baits as close to the bottom as possible, trolling in 8 to 15 feet of water. If you're not snagging up once in a while, you're not going to catch as many fish. Having a good lure hound to retrieve snagged lures is a must. We usually troll with the kicker motor at 2.4 MPH, with water temps is between 60 and 70 which is the best time to catch them for us. Slower if cooler, quicker if warmer. I have caught them trolling 3.5 for strippers and I have had them hit suspended baits when we were stopped dealing with a fish on another pole. When trolling the banks, we troll 3 rods, one with a bait that runs 6 to 8 feet on the bank side, one that dives deep quickly at the end of the propwash (about 30 feet back) right behind the boat, and one that runs 12' or so on the outside. I set the steering wheel straight on the boat and steer with the trolling motor constantly watching the depth finder to avoid shallow spots and maintaining the boat in 10' of water. Most of the time the bait against the bank will catch the most walleye. Some days it will be the one in the middle. The bait in the deepest water will always catch the biggest walleye and also the most stripper. I have found that after the sun goes down for the last half hour of the day that the fish seem to come up shallower so we will shorten the length of line we have out and bring the lures up off the bottom. This also helps prevent hang ups which are not any fun once it's getting dark.

Since the mussels have shown up, getting cut off is a bigger issue trolling close to the bottom. I use a good leader behind 15/4 or 20/6 power pro braided line. I prefer using the yellow power pro because you can see it better especially when it starts to get dark. I like to use a 10-pound piece of leader 8 to 10 feet long. I only use two types of leader material - P line and Seaguar. When we are getting cut off often, I will go up to a 15- or 17-pound leader.

We fish mostly flicker shads and minnows because we have found them to be most effective. 7's and 9's usually, sometimes 11's if we need to go deeper to find the bottom. I prefer the ones that look like something that actually swimming in the lake, the wife likes the pinks and orange and purple ones. We have caught them on Rapalas and other crankbaits as well.

I have had good days using bottom bouncers. That being said that's me fishing by myself in the mornings, because my wife most of the time refuses to fish this way, and she does not fish before noon usually. I often tell people if the first time someone took me fishing and taught me to bottom bounce and that this was what fishing is all about, I would have been a golfer. Under the right conditions it is a very efficient way to put them in the boat.

I will rarely tip a single tail grub with a piece of nightcrawler, it just does not allow the bait to swim properly. I much prefer to use a tube jig and stuff the piece of worm on the hook and up inside the tube jig. I will find a likely looking bank and just drift or troll around 1 MPH down the bank keeping the bait in 8 to 12 feet of water simply picking it up a foot or so and setting it back on the bottom. If you feel anything thing that resembles a bite, or lack of weight or simply see line moving off, lift the rod a little and if you feel any weight, set the hook.

Biggest problem a person will have is finding good areas to fish. 1% of the water will hold 99% of the walleyes. It sometimes takes 3 or 4 days to find them and what they want. Most people don't have that long or the patience to find them. Then when you do find them and come back a month later, the water has dropped 4 feet they have moved, and you start looking again.

As far as where to look for them, long flat points that go way out into the middle of the lake or bay, and flats in 8 to 15 feet of water, are the best. Any rocky shoreline, especially with a lot of points on it are good as well. There are a lot of these in GHB, before you get to good hope bay and till you run out of lake going further north. My favorite spot was further north. In the fall of 2017, we caught over 270 in 3 trips (about 15 days of fishing) in an area about 10 to 12 acres. I shot an elk that year in September, and it took up less room than the walleye, crappie and smallmouth did in the freezer. Just two short years later in 2019 we took pictures of cattle grazing right where we were catching all those fish.

As far as size, we have probably caught 50 or so in the last 10 years that were 3.5 to 5 pounds, at least 40 of these were caught in late November to mid-December. The large majority of the walleye we catch are 17 to 18 inches. The further north you go usually the bigger the fish are. If you are catching a lot of 20-to-21-inch fish, you know something I don't know, or your tape reads different than mine.
This is a great post! I am extremely happy I posted started this conversation. There is one thing about walleye fisherman… we are all usually pretty tight lipped so I was afraid this thread would die after my post. Thank you for you input flipper, I could not agree with this entire post more. I will say our biggest walleye probably a 7 lb fish came out of around 3 feet of water. When those big females start eating after the spawn I have caught them sight casting where I grew up in under a foot of water in the rocks. Hope we can keep this thread going! Getting me fired up for May and June!

I think there are a lot of big walleye in the lake, there is just a lot of water for them to be in. It is nothing in Lake Erie to catch walleye 70 feet down in the summer and that is usually where we found the big ones. When we would fish Erie for big fish we would fish the deepest part of the lake 70-80 feet where I fished, use very large crankbaits or spoons and just stay after it. You wouldn’t catch many but the ones you did get were all over 6lbs most closer to 8. It is hard to try all day for one or two fish when you can catch 100s of the perfect eaters casting jigs or trolling close to shore.

The picture I posted was full moon night fishing at Starvation😂
I met Flipper and his dad 30+ years ago at Pelican Bluegill fishing.
