In reply to: Thanks to Jimbo
My only hope with feeding is to ensure we get as many fish as possible through the hot months. Any time your catching LOTS of big fish, the excitement does drop. Go spend some timne in the San Juan in NM. And that is a natural river full of big fish. This holds true for trout, bass, tuna, whater. I feel very appreciative to be able to fish a river where we can catch big fish. Thanks Jimbo!

Although I think that there are good arguments against feeding the trout, the one adduced by the board makes no sense. If we need to feed the fish at any time, the summer for example, to have significant holdovers, then our fishery is not self-sustaining. Winter feedings would have nothing to do with trout survival. The only feedings that might help some, if not, especially during low flow periods, most trout survive are during the summer. Consequently, if such feedings are instrumental to having a year-round fishery, then, by definition, this fishery is not self-sustaining.
However,if we removed the self-sustaining, part, the board’s argument is good. There is something artificial about a fishery where the fish are fed. It does feel a bit like fishing in a hatchery. So, I would also be against winter feeding, but, as explained above, not for the reasons offered by the board.
Finally, I’m less concerned about what the general public thinks than what is good for our river’s health. If feedings during any time of the year were shown (i.e., with good, objective data, not anecdotal reports) to be an integral component of our efforts to promote the vigor of our river and its residents, then I would support it without hesitation.

Well thanks everyone !!!! I have been walking around in a bit of a fog lately. There have been many things going on in my life that have me distracted and sometimes I wonder how I appear to everyone else. It is always very helpful when we have so many members willing to help with the stockings, as it is a lot of work carrying all those buckets into our LAP sites.
The first stocking the fish were a little smaller than we are normally receive from the Hatchery, then again high numbers are always nice on the first load. I am hoping they get a little larger on average in the next 3 loads. I will finish arranging the last two stocking dates and get those permits in hand. I wanted to do more feeding of the Trout through the winter and brought it up before at the recent GRTU Board meeting, but they voted it down. We will continue feeding them through the summer, so we still have that going for us.
It’s very nice, when I hear from our members that they like the way things are going.
Thank You !!!!

GRTU V.P. of FisheriesIn forum: Lease MembersTopic: GRTU V.P. of Fisheries
Dan Cone has been the V.P. of Fisheries for a number of years and has implemented several new programs like, the feeding of our Trout through the stressful summer months. This has led to an increase in the number and health of the Holdover Population of Trout as everybody has seen. Dan Cone has stepped aside from the V.P. because of some Family Issues, which require so much of his time, that he felt he could no longer give the V.P. of Fisheries the attention it deserves. Dan asked me if I could step in and handle the position for him. I said it would be my honor and the Board accepted this change. I would like to thank Dan again for the dedication he has shown to GRTU and the V.P. of Fisheries. We are all the better, for the time he has served!
Thank You

1) The amount of the food available to the fish is dependent on habitat. And the main limiting thing right now is flows, or the volume of water the fish and the insects and prey fish have to occupy. So, the low flows have a more complex impact other than just temperature on the health of the game fish in the river. More flow increases the area and volume of the aquatic habitat everything from the smallest Midges to the largest Stripers can exist and multiply. It also increases the dissolved oxygen as it tumbles and moves downstream. Higher flows also work to remove silt in the river, allowing for more pore space in the streambed gravel, and thus increased areas and populations for the insects and small prey fish that live there.
When the flows are low and by that I mean below about 100-150cfs, the river has a limited capacity to sustain the top predators, like the Trout. So, feeding them during the summer when temperatures are high, especially when flows are low, the Trout are under a lot of stress. The higher water temperatures mean the fish metabolism is also running at higher level and they need more calories to sustain themselves. The feed is a very high calorie supplement that provides those calories and then some. You can see just how fat and healthy the survivors are in the fall after feeding them through the summer.
Should we feed them all year? That is a question we have not addressed. The supplemental feeding certainly keeps their stomachs full and they become accustomed to the size and timing of those feedings. Anyone who has tried to fish after the morning feeding are over, knows they will strike flys less frequently than on the day no feeding occurs. Now during the actual feeding, they are whipped into a frenzy and will hit flys floating in the feed itself. During the colder months, as water temperatures fall, the fish seem to do better because the metabolisms slow down and they need less calories. We also seem to have better hatches of Caddis and Mayflys during the winter and spring. It might help to feed the fish some during the winter and maybe the Fishery Committee should discuss this and talk to the board about it. I will bring up the subject this season.
2) Stream improvement projects were proposed decades ago. It is quite complicated as the river is controlled by the CORE (Army Corps of Engineers) and GBRA, with TPWD supporting. You can not just move some rocks around and permanently change the stream bed in any way without the approval of the CORE and GBRA, because Canyon Lake is primarily a flood control project. Thus, the primary function of the Canyon Lake Dam is to control flows downstream to prevent flooding of the areas adjacent to the river. Delivery of water downstream for agricultural or municipal use and power generation are secondary, with river biology falling behind everything else.
The first things we did accomplish to improve the Fishery were limited harvest regulations and the Flow Agreement. Both of these success’ have helped increase the possibility and realization of a Trophy Trout Fishery. That and with a strategy of the size and numbers of Trout we stock has greatly improved the fishing for Trout in the Guadalupe.
The question of what species of Trout to stock has never definitively decided. We are still playing with the idea that Brown Trout might be better at providing a self-sustaining Trout fishery. But so far, they have not been, and we don’t really know why. We do know that excessive siltation and other river predators have been a limiting factor on natural reproduction. We have stocked Brown Trout in the past of varying sizes, but they do not seem to hold-over as well as out specialized temperature tolerant Rainbow Trout from Crystal Lake Fisheries. Chris Johnson is spearheading a Whitlock/Vibert Box planting of Brown Trout eggs in an effort to see if a born in the river Brown Trout can establish a reproducing Brown Trout population or even a viable population of catchable Brown Trout.
GRTU proposed several stream improvement projects decades ago, primarily to better the habitat for the benefit of the Trout. We actually did get approval for the movement of aquatic plants into the upper river after the 2002 flood to restore the plants lost during the scouring flows.
We also proposed the stabilizing if the banks of Spillway Creek with willow trees to prevent excessive sedimentation from entering the river. That has been on hold for approval forever.
We also proposed a streambed modification in the Potts area, to prevent excessive impacts of high air temperatures on the river’s water flowing there and then affecting water temperatures downstream and limiting the preferred temperatures/habitat for the Trout downstream. We went so far as measuring flows vs stream width (most know how shallow and slow the water moves because the river is so wide there) and using ground penetrating sonar/radar to measure the depth of the gravel and bedrock in the area. The idea was to create structures that would naturally narrow and deepen the channel to speed the volume of water there and lessen higher air temperature impacts. Again, the base work was done, but approval to proceed was never given.
So, GRTU has been thinking about many things to improve the Habitat, better the survival, and even natural reproduction of the Trout populations in the Guadalupe. But it’s all the red tape that has held us back. Now these projects are still on our minds and when possible, we will do what is allowed to make the Guadalupe River a better Trout Fishery.

You’re right, Jimbo. The feeding program leaves us with a lot more, and a lot healthier, trout than we would have had without it. I should add that the people who do the actual feeding are among the nicest and most helpful folks one is likely to meet on the river.

I just wanted to remind all those who have gone through the LAP registration process that signing up for this season’s LAP closes midnight Tuesday October 8 !!!!
We still have about 100 potential LAP members that have qualified but not signed up. Don’t miss out by waiting too long to pay for this year’s LAP season. We need the funds because the cost of Trout has gone up again this year $7/lb to $7.70/lb and we need the monies to support the program’s: fish, leases, and feeding program. And let me tell you, this feeding program that we established, is making a HUGE difference in the quality of the Trout holding over through the summer to the fall. I went fishing last week and these fish in the upper river are not just healthy, but down right fat !!!!
Thanks for everyone joining the LAP program. It is responsible as the primary generator of funds to pay for our stocking efforts on the Guadalupe. And you know what a difference it makes in the quality and numbers of Trout in the river to catch !!!!
See You on the River

The New Braunfels Fly Fishers annual holdover Tournament will be held on November 2.
This is NBFF’s one fundraiser of the year and helps support not only the club’s guest speaker budget, but also provides the money necessary for NBFF to provide each participant of the GRTU Youth Camp with a gift bag that includes items such as a fly box, hemostats, nippers, flies, and other accessories necessary to help them get started in fly fishing.
NBFF members spearhead the effort each summer for the GRTU trout feeding program, which has resulted in a marked increase in the numbers as well as the improved health of the rainbow trout that GRTU stocks each season.
Data collected from the tourney is shared with GRTU to help them better determine the overall viability of trout in the Guadalupe River tailrace.

In forum: Lease MembersIn reply to: GRTU Spring 24 River Cleanup
We had a terrific turn-out with somewhere around 70 people showing up to help with the spring cleanup. In fact we had one group come from as far away as Rockport to help pick the trash up and out of the river.
Here is the crew I took to Kanz and JDL to clean those areas….
Everyone crossing the river to start at Kanz….
This group filled over 20 bags…. Good Goin’ !!!!After finishing up at JDL, Ron McAlpin was there with another “Trout In The Classroom” Rainbow Trout Fry release…..
We talked about the Guadalupe, our efforts to enhance the Trout Fishery, what is an evasive species, the Guad’s special harvest limits, and other conservation topics.The trailer being filled up with the collected trash back at Lazy L&L….
This and another couple of pickups beds worth was collected to help beautify our River….
Awards were given out for the most unusual trash collected. This boy and his father found and retrieved a wrought iron patio table. He received a flyrod for his efforts.
Another flyrod was given out for a Drone that was found.This volunteer came from Rockport and received shadow box with hand tied flies of a dragon fly and some bees, for the furthest a group traveled for the clean-up.
The New Braunfels Flyfishers were also well represented….
A special “Hello” to Ron Demeyer (on the far right) who wrangles the volunteers for the Trout Supplemental Summer Feedings for GRTU.All in all, what a fabulous group of volunteers to help doing the hard work of beautifying our river and share some burgers, drinks, and stories of the day and other days on the river. This is the GRTU in action that gets little attention, but it’s critical work to enhance the river and the fishery.

A Little Refresher Course
When I was drafted to be V.P. of Fisheries many years ago we had been stocking very large Trout in the river for several years. Then V.P. of Fisheries, Bill Higdon, had spoken with then river biologist Steve Magnelia and he had come away with the idea that Trout larger than 18″, would better survive when marginal conditions hit the Guadalupe in the summer. He had asked Steve Magnelia, if these larger Trout we had been stocking had higher rates of survival in higher water temperatures than smaller Trout. Steve answered that adult Trout did have higher survival rates when conditions got tough. Bill throught this was an affirmation of all the Trout, well over 18″, he had been stocking. Unfortuately Steve was talking about adult trout, and Trout become adults/sexually mature when they are 12″.
The membership was commenting that, yes they were catching giant Trout, but numbers caught during a day’s fishing were not what they had been. Then add to it the huge surge in fishermen fishing the Guadalupe River because of the very large Trout there and many harvesting these large Trout, things were not optimal. Previously we had been stocking generally Trout that were 10-14″ with a few trophies. Our strategy had swung too hard to the other end of the spectrum.
So new to V.P. of Fisheries I talked to Steve myself. That’s when I found out what the river biologist meant by “Large” trout (being 12″). I decided we needed to adjust out stocking strategy. I had some ideas and presented them to the board. The Board decided they sounded good, but we needed to find out what our membership wanted, because they were the ones paying for it with their LAP membership fees.
So we decided to send out a survey and give LAP membership a chance to pick between some alternative strategies. We explained that because they were going to pick the size of Trout we stocked they would also be picking the numbers of Trout we stocked since we buy them by the pound. The overwhelming responce called for 75% 14-18″ and 25% > 18″. Back then we were only stocking Rainbows from Crystal Lake Fisheries. We asked CLF if they could grow their Trout to meet our needs and they said yes.
Most years they have met our needs and stocking startegy. This past year they had their own problems raising Trout. They had problems with getting the feed they needed to grow their Trout out. You can thank COVID for creating this(another) problem in the supply chain. They also had a problem one year when a flood at the hatchery washed most of our 14-18″ fish down river, but that was a rare event.
During my tenure we saw expenses rise every year. So did the demand for LAP memberships. When I started the demand for membership in the 550-650 range. Every year we saw a rise in demand till it soared above 800 and decided we needed to cap membership because of limited access and easily meeting the expenses for Trout and Leases. We also saw the change in the regulations. We long wanted to protect the upper river from harvest. The new regulation: from 800 yards below the dam, to the crossing at 306/Whitewater, daily harvest of 5 Trout, BUT ALL Trout 12-18″ must be returned to the water, only 1 Trout(of the 5) could exceed 18″, all others had to be below 12″, and they must be caught using artificial flys or lures.
The last couple of years the Board has heard the request for more LAP memberships, so we added to those numbers, but still demand far out stripped the available memberships. I don’t think we will again ever be able to satisfy all the demand for all LAP memberships desired.
So here we are today. Doing our best to meet the demands of LAP membership and still providing a healthy fishery. I think Dan Cone, our new V.P. of Fisheries and the Fisheries Committee, has been doing the very best thing possible during these COVID years. One of the best things we has done (under the radar of most LAP members) is the suplemental feeding through the late spring to early fall. And without a doubt holdover has been better these last 2 seasons because of those feedings. We also have seen the constraints in the supply chain that finally resulted in not having the normal availability of almost any size or number of Trout we wanted this year. The hatcheries which grow this year’s Trout last year, have not been able to produce all those Trout for this season’s stocking. This is a national wide shortage.
As supply chains are restored I think you will a return to the availbility of almost any size or number of Trout we desire. The Board has also been talking about another survey of LAP members sometime this spring. The question about the sizes we want to stock can be addressed again, as will be other concerns. I think we all want some large Trout swimming around in the river that provide the thrill when hooking and landing these monsters. The question remains how many we want to stock? And of course we want to let the hatcheries know what sizes we want well ahead of time so they will be ready next season.
The GRTU Board, the V.P. of Fisheries, and the Fisheries Committee, will continue to do the very best we can to establish the best Trout Fishery we can and satisfy the desires of the LAP Membership. It is not easy. It takes 1000s of man hours to make it happen and still some years things are just out of our hands. But we will continue to try and improve the fishery. Eventually we will get back to river enhancement projects which should provide long term results, push for more restrictive regulations, and continue to promote catch and release of these sportsfish.

And coffee beans, although not durable, look a lot like trout chow.
Alex, JC, Trey — really great review and reminders of tactics and technics to use on any trout stream!
I think that the quick change in trout activity on the Guad ,both on and off, is greater than other tail water fisheries , based on my experiences. So could it be due to two things that are unique to the Guad; (1) extreme pressure,even greater than the infamous Frying Pan, and (2) hatchery fish that do not carryover to acquire feeding behavior more typical of native/ wild or resident trout ? Maybe they do feed in short bursts just as trained at the Crystal Lake hatchery , just asking?
In forum: Lease MembersTopic: Tres Emergers On the Guad ?
I’ve watched a lot of trout feeding on emergers below the surface on the Guad and on Crabapple Creek. In the Fall 2021 issue of “TROUT”, Dave Whitlock describes his favorite way to catch big trout – a triple caddis emerger rig which he describes in more detail at http://davewhitlock.com//www/wp-content/uploads/2016/04/FFMS-150028-WHITLOCK.pdf I’d be interested to know how this approach might work on the Guad after the fish acclimate from the hatchery diet to what lives in the Guad.
In forum: Lease MembersIn reply to: What’s going on with GRTU?
No matter what we do, we are pretty much maxed out considering the number of leases and number of parking spots they make available right now. We need more access spots and parking spots before we increase the maximum number memberships available. We have gone from about 550 memberships just 6 or 7 years ago to almost 900 all toll, and we’ve lost a few sites. We’ve heard from many members saying there are already too many memberships sold. It’s between a rock and a hard place no matter what we do.
So until things change,… my recommendations,… be like Jimbo. Get up at the crack of dawn on Oct 1 and sign up in the first minute it’s open. I’ve had no special treatment all these years of signing up and I’ve been a continuous member since the 80’s.
I wish we could just solve all these problems by leasing every site we’ve ever had, but some have been sold private, or bridges were burned because of violations. This is not as easy as just calling every outfitter and getting them to sign on, many don’t want any part of anything which is not pay per day at their office. V.P. of Fisheries is “NOT” an easy job. Dan Cone is carrying on in a fine tradition, doing a great job, and we are Lucky to have him! He’s even added to aspects like Trout feeding during late spring through fall. Soon we will have a better Brown Trout (genetics) and in stream river restoration.
