Lake: Pueblo Reservoir

Eurasian watermilfoil

Post By: motoxxx43      Posted: 8/6/2019 1:17:29 PM     Points: 2148    
It appears this crap has taken a strong hold here at the reservoir. Started noticing it last summer in a few areas. Now those areas are covered in this invasive weed and it has spread to other parts of the lake. This stuff is nasty and really doesn't have any redeeming qualities. Not sure if anyone else has been dealing with it but I'm afraid it's here to stay. From what I've gathered it is eleven mile too.

Yep it sucks, that is why we get a blue paper when we leave the inspection station. I know they can kill it to a point but not sure to what extent. My understanding it that it is in Spinney too. If true it can spread thru the whole South Platte system.

Many years ago I fished Minnetonka and the guides up there were happy to get that weed! They said it made the fishing a lot better especially for northerns and muskies. We caught a few northerns that day and a MONSTER muskie.

What's the downside in a lake that has virtually no vegetation?
 Reply by: motoxxx43      Posted: Aug. 11, 8:08:02 PM     Points: 2148    
I suppose this is your idea of something good for this lake?

6 years ago the first time I fished this lake there was weeds like that and then the next year the water level was high enough that it wasn't an issue{ just getting over the drought from 2012). it seems that the lake has had stable enough water levels for a few years that it has returned. I would think for the largemouth bass it would be beneficial. none of the fish in pueblo are native anyways I don't see why people would be upset about this, because the fish that inhabit the lake will use these weeds for food/structure. it seems that most people on here complain about how much of a trout state Colorado is so I don't know why people are complaining about this when th fish they want to go after aren't even native to this state and most fisheries even the coldwater ones are basically an aquarium.

if you want a good largemouth bass fishery you want these weeds. people from Denver are destroying the mountain fisheries so might as well get used to going to cities to fish and be around a bunch of people that ruin the experience.

Before thinking this is a good thing I suggest reading up on it. This body of water serves as a reservoir and flood control operation first and foremost. The fact that it is used as a recreational body of water is pretty far down the list of priorities. When invasive species are introduced they have to be addressed (Zebra mussels). Remember that extra $25 charge per boat registration we were dealt this year? Thats just to continue the operations they have going right now. When this milfoil becomes and actual problem who do you think is going to have to foot the bill again? Not sure how the bodies of water in the three photos above look usable to anyone. Not only does that crap clog up your outdrive but when it get that thick it in the shallows it is a huge mosquito breeding ground. Not worth the extra "habitat" for bass, period.

Invasive
Illegal
Same thing to me

Looks good to me, almost always improves fishing. Furthermore, the layout of the reservoir is going to prevent it from becoming out of control. Will definitely not affect it's utility as a water storage and recreational lake lol. State and federal agencies have so little to do they get bored and make big deals out of small issues.

Are you certain that this is Eurasian Watermilfoil (Myriophyllum spicatum)? or is it one of the many native watermilfoils?

Eurasian watermilfoil is not native, and can be a major issue in certain lakes. How bad of an issue it can be has to do with the "layout" of the lake as well as the rest of the lake's underlying ecology--water quality, clarity, average temperature, usage, etc.

So making a determination of whether this is "bad" or "good" depends a lot on a whole lot of circumstances, as well as what you as a fisherman/recreator value. Values differ among different people. Yes, eurasian watermilfoil has been "good" for largemouth bass *in certain situations*. It's been "bad" for other forms of recreation, and other species of fish, in other situations.

Me personally, I dislike this "what can it do for me" mentality because it relies on way too many circumstances that are impossible to predict or measure. It's also a selfish, boring way to look at nature. To me, eurasian watermilfoil isn't native and therefore doesn't belong here, end of story. The native plants are valuable in and of themselves, and besides, they can do the job just as well.

brookie, I always love your insight, and most times agree with you. And I'm not disagreeing with you right now, but the other side of the argument of it's not native it shouldn't be here would be, we wouldn't have any gamefish on the front range if we only had native species.

However, plants are harder to control than fish (most of the time, some fish are hard to control, like Asian carp), and in their native waters they likely have something that eats it to control its growth. It can get out of control quickly in an area with no species that consume it.

I also wonder if an out of control growth on non native plants can also cause winter kill when it decomposes under the ice?

Thanks brookie, that's the point I'm getting at.

As for winter kill, I have no idea. I know it smells horrible when the water level drops. Not that that ever happens here...

Its a shame everyone makes a big stink over invasive or non native aquatic vegetation but Ive never seen any effort to introduce native vegetation.

I will admit Im pretty bummed out when finding a pond or small lake packed with the stuff has been treated. I suppose for the average Joe dunking bait or tossing his Rooster Tail whod prefer a brown bowl of water it can be a problem.

Brookie, it is a RESERVOIR bro?!?!??? There is nothing natural about damming a river and stocking it with non-native fish. Be real here.
 Reply by: brookieflyfisher      Posted: Aug. 13, 12:57:28 PM     Points: 6121    
Respectfully, I don't think that's a good viewpoint. From a native-ecology point of view, mistakes were made in the past (creating a reservoir, filling it with non-native fish, etc) and we have to live with those decisions.

But that doesn't mean adding more invasive species is a-ok.

The fact that we, as recreational fishermen.. think that we know more about the risk, reward, benefit, and challenges of an aquatic plant than the people who manage it is comical...

I have had the pleasure of chatting with several CPW experts in their field... One thing for certain, they know a whole heck of a lot more than I do..

EDIT: There are certain members such as Brookie that are educated in this field, my comment does not necessarily apply to them.
 Reply by: brookieflyfisher      Posted: Aug. 13, 5:27:59 PM     Points: 6121    
Aw thanks Ajax, but you're right, I am sure the CPW is more aware of the situation at Pueblo and the rest of the AIS problems.

And I'm aware of the irony of me, whose username is after a distinctly non-native species (and a rather destructive one at that), lecturing about native species.

But I think that's where the disconnect is. We think that because things were done a certain way in the past, or that mistakes were made, or whatever, that we have to continue down the same road. We don't. We can simultaneously enjoy non-native fisheries while asserting that this is the high tide, and that we're going to work to ensure that we don't cause any more damage than we already have.

Yup Luke, ALL of the lakes listed ^^^ SUCK. Nobody should fish any of them, not worth the time.

Id love to get back into Ward Road and something tells me Panama might have some great fish as well..
