Pond Issues

All bodies of water are different, different sizes, shapes, depths and many other factors that make no two ponds alike.  This means that they are all different ecosystems.

We have 7 different water retainage areas on the course. I will go over each of them in this post and describe the issues that we have, some historical information and the efforts that we have put forth.


First off #7 has a very special place in my heart, My beautiful wife and I were married on the edge of that pond.  It is one of the 2 fondest memories that I have, the other being the birth of my son.  This hole is also the "signature" hole for the golf course.  It is a retainage pond.  It has had issues in the past with algae, not bad issues but issues none the less.  This year there was a die off of fish in that pond.  The cause of the fish die off was a lack of dissolved oxygen in the water column.  There were several factors that led to the oxygen burn.  The main factors were water temperature, having a fountain missing, and a hot stretch of summer followed by a cold rainfall.  The process of a fish kill is a rough process.  When any organism in a water body dies the decomposition process burns oxygen in the water, so a body of water that is low in oxygen gets lower.  It's like rolling a boulder down a hill the further it goes the harder it is to stop.  However, we had employees out there cleaning up dead fish with pool skimmers trying to keep the amount of decomposition and odor to a minimum.  I think we did a great job responding to the issue in a timely fashion.
A brief history on this pond.  It has gone dry 2 times since the construction that I know of.  Once was about 5 years ago and once was well before my time. 
The homeowners that live around the ponds have been managing  and maintaining the fountains in the ponds for the last 10+ years.  We met with that "Pond HOA" and they have given us the control of the fountains.  They did a great job with those fountains for a long time.  We have already changed out the nozzles on the units to throw more water and create more oxygen and surface cooling.  we have gone from 400 Gallons Per Minute to 1500 GPM, a large difference.  I am currently investigating different fish species to introduce to this area.  predatory fish like bass to keep the number of smaller fish down, triploid grass carp to help keep the ponds clean and we have used tilapia in the past to help combat algae.  I am also researching colorants for this area to block UV rays and prohibit algae populations.


This pond has no issues.  It used to be a hazard on the course that had dried up because of the inability to fill it.  Since gaining that ability the pond has sealed up and is holding water nicely and is again a hazard.


This pond is the start of a storm water runoff system.  The water that runs into it comes from HWY 231 and surrounding areas.  It used to be one of the sources of our irrigation water.  It has issues with primrose, an aquatic plant that is easily controlled with 2,4-D or Diquat.  Both of these herbicides are acceptable to apply in water bodies and safe to fish.  Since it is a storm water system the water column is changed over frequently with large rainfall events.  I have simply not had the time to treat this pond lately and that's on me.  This pond is also about 4 feet deep and has about 3 feet of sediment in the bottom.


This pond is on the far right as you drive in the neighborhood.  It is the same scenario as #11 an storm water collection system that used to be part of our irrigation source.  the pond on #11 feeds to #12 and It also gets fed by all surface runoff from areas south of this from Runnymeade Drive north.  So this pond gets double the input that #11 gets.  It is about 4 feet deep with a rock bottom.  UV rays penetrate it easily to allow algae and other plants to grow in it easily.  In the past there were major algae issues with this area.  The neighbors banded together that lived around this area about 9 years ago.  They purchased and installed 3 fountains with IHGC's blessing, 2 in #12 and 1 in #13.  These were small 110 volt fountains that did not exchange much water and could not cool off the water column because there is no cool water to draw from in the summer on a 4 ft deep pond.  After a while these fountains were just sucking up the muck on the bottom of the ponds and getting clogged up with debris.  They became more of a maintenance nightmare than they were worth.  It was a good effort but a poor fit for the process.
That being said we do not have an algae issue in this pond this year so much as we have a duckweed infestation.  Duckweed is a naturally occurring plant that is one of the smallest complete plants on earth.  It is about the size of a pencil tip.  If you are interested in researching the plant click on the highlighted name above and it will take you to Wikipedia.  The problem with duckweed is that it is very hard to kill in our environment  the plant already has a seed by the time it hits the surface and releases that seed when killed so surface herbicides, diquat, do not work well.  There is a product that I tried at the correct application rates, "Sonar".  This herbicide has the ability to treat the entire water column, kill plants and seeds.  Its issue is that it needs to be active in a body of water for 48 days and it is very expensive.  I estimate that our application was active for about 7 days before the rains flushed that chemical out of the water body.  It is really hard for me to justify spending someone else's hard earned money on a issue that is almost guaranteed no win scenario.  Do not misread that statement, that does not mean that I am not going to do anything about it, it means that I am going to be very careful about what I do.  I had attempted 3 diquat applications this summer and 1 sonar application.  You also have to remember the statement from #7 pond about organisms decomposing in relation to oxygen content.  So if we kill of all of the vegetative material in a 4 foot deep pond at once it will burn off oxygen and "shock" the pond thus potentially killing fish.  I have to follow the rule of thirds when treating the ponds as not to create a different problem.  the rule of thirds is to never treat a heavily invested pond by more than 1/3 of the surface area at one time as to protect the other ecology in that environment from damage.


This is the closest pond to the road on the right as you drive in.  It is also part of the storm water runoff system and has the same issues as #12.  The duckweed moves with water and gravity, down stream.  This pond would have small algae blooms in the Spring each season as the temps came up.  But, it had one natural defense, it is a very deep pond with flow through.  The depth allowed the water to remain cooler and reduced the ability of UV rays to penetrate to the bottom and breed algae.


This pond is on the left side of the entrance as you drive in the neighborhood.  It is our irrigation holding pond.  It contains IHGC's water once it is in this pond it is IHGC's and no one else's.  the brick house on 231 side is our pumping station.  It is state of the art and we are very proud of it.  The water in the pond is effluent water the same kind of water that many golf courses around the town and the world are trying to use.  We do this in order to reduce our environmental footprint.  We are not the first golf course to use effluent water and we will not be the last.  Effluent water can be from many different sources but ours is processed treated water.  It is not sewer nor has it ever been water that went down a toilet.  One quality and burden of Effluent water is that it contains nutrients Phosphorus particularly which is a key food source for algae.  Also the effluent is warmer and creates another algae breeding scenario.  You will notice that it can get kind of a pea soup look in the summer, this is green algae trying to bloom in the water column.  About 7 years ago in the infancy of our Effluent usage we had a complete coverage of algae on that pond.  After that we installed 2 Sonic Devices that emit ultrasonic sonar wavelengths that actually destroy the algae at a cellular level as it is trying to form.  These devices have done a great job in control of algae blooms.  Remember this is our irrigation source and we apply this water to the grass on the golf course so there is the concern of herbicide transference and damage to the course by herbicide applications in this pond.  I do not believe that we require any herbicide applications to this pond at this time.


This pond is having trouble holding water at a certain depth  It is a small hazard pond on the course.  we may try to add some bentonite to the banks in the future to seal up any leaks.

This season we have had several complaints made to regulatory authorities with concerns about our water areas by neighbors of the course.  I have been working with TDEC since the complaints started on #18, 13 and 7.  They are well aware of the issues that we face.  I have explained with them what our management attempts are and have been.  They have agreed with my strategies.

There are other methods of algae control such as sub surface bubbler systems that release air at the bottom of the pond and help create aeration and circulation of the water.

I am happy to accept phone calls on the issues or any golf course related issue.  I can also be found on social media @bradmarcy on Twitter.

Course Alterations for 2017

As the golfing season is upon us with the first round of the Masters on TV this afternoon.  While we were installing the irrigation system this Winter we also took the chance to make some course alterations.
The first thing that we did was course yardage.  This has been one of our most common complaints in the past.  Well, we have added yardage tags to 350 sprinkler heads.  I feel like we are so well marked that we might remove the blue red and black pavers in the fairways and posts at the path. 
Hole Number 6 had the most noticeable changes.  First off the left greenside bunker has been filled in.  I still believe that it was one of the hardest situational shots on the course, unless you were smart enough to putt out of it.  Next the front right greenside  bunker is in the process of a face-lift.  We have removed the steep face and are in the process of regarding the base.  We will drain it, line it and add some new sand and were good to go.  Then we opened up the exit area back to the path.  It used to be about 5 yards wide between berms.  Now you could drive the space shuttle through the exit area of the hole.  I hope this allows for better traffic wear patterns.
On hole 8 we had the, while structurally sound, clunky bridge that I built removed.  In its place is a concrete cart path bridge that wont knock out your teeth when you drive over it.  We also removed the old grass bunker left of the fairway. 
On hole 10 we extended the rock walls surrounding the fairways.  Also, we filled in the 3 grass bunkers on the left side of the fairways.  Lastly we added a more friendly Ladies tee that is waiting for sod. 
On Hole 12 we got rid of the dip in the cart path that went through the creek bed.  We replaced it with a new cart path bridge. 
On hole #14 we removed the left side fairway bunker.
On hole #17 we removed the old grass bunker on the right side of the fairway.  It will finish its transition into a new Ladies tee.
On hole 18 you will notice that you are driving through the water in the spillway.  That is because of the new stream that has been routed through the 18th hole. 
Hopefully I have not forgot any of the new features but it is entirely possible that I have.

Irrigation Renovation Update 4-6-17

Well, we are in the home stretch, although there is still a lot of work to be done.  The guys with Nutt Construction have done a great job with a monster of an install job.  They have been flushing out the lines for the last two weeks.  This has to be done to remove the debris from the interior of the lines.  This could be dirt rock or PVC shavings that somehow got in the pipes and could stop up a head when it tries to go from ON to OFF.  They were flushing out the Turf Nursery Area and the res/com system around the club grounds today and those were the last two areas to flush. 
I have been running water for about a week now.  I am trying to find bugs in the system, test capabilities and find programming thresholds and faults.  Every morning I am riding the course looking for weeping heads, heads that are stuck on or other anomalies that may have taken place from the night previous.  Hopefully the punch list made each morning will diminish with time.  I have heard from some residents about sprinklers hitting decks or patios.  If you have one of these issues please contact me and let me know.  I will not get to see every one of the 1,700 heads run.  I have moved our watering times to 10:00 PM so there will be less likelihood of something hitting a deck when you might be eating dinner.  I have had programs running at 7:00 PM and 6:00 AM so that I can see or get feedback on the process but it is time to put them on in the dark. 
The parking lot is starting to get vacated just in time for tournament season.  We still have a lot of pipe to get out and some other items.  Thank you to the neighbors who were very patient with us while we stopped traffic to load the Semi trucks on Calumet Trace with equipment, you were very patient with us. 
While the project is winding down there is still a lot to do.  there are a lot of areas that have been torn up and need to be repaired.  We have been re seeding areas this week and are waiting on some sod to come in any day now.  We will still have a small construction crew here for another 3-4 weeks cleaning up and helping fix scars and smoothing out rough areas.
Once again, Thank You to Nutt Construction, Aqua Turf International Consulting, Rainbird Golf Products, Keeling Co., Ole South Excavation, the Residents of Indian Hills Subdivision and All of our golfers.

Irrigation Renovation Update March 8th

 Currently all irrigation has been installed on the playing surface of the golf course.  Hole #7 was the last hole to be installed and that was completed on Friday.  The driving range was completed Sunday and back open for play on Monday.
There are only 2 areas left to irrigate.  The club grounds with a res/com system and the nursery area which is about the size of a par 4. The nursery area runs parallel #2 on the other side of the rail road tracks. Apparently this area was once intended to be part of the course but for one reason or another it was abandoned.  It has been a bone yard or a dumping ground for the last 30 years. The whole thing was an over grown cedar thicket.  So we had it cleared out with a grinding machine. We found that there had been some clearing and shaping that took place somewhere in the past.  Piles of boulders and piles of quality tee soil piled up in areas. It was really pretty cool to uncover. I would love to eventually have a full sod nursery with An acre of bent, fescue, bermuda, and zoysia at some point in the future.
The pump is in place and the pump house is dried in.  Brick is scheduled for the exterior on Monday and the electricity will hopefully be run this week.  Would love to be blowing out installed lines in a week.
We have some cleanup still going on on the front nine. I would hope to get all 18 holes back open for play on next Saturday. We still have a lot of concrete cuts to pour and rolling to do though.

I got a new toy

I am now a proud drone owner and operator.  If you have spoken to me on the subject, I had purchased a GPS based drone 18 months ago from a startup company by the name of Lily.  Well, I found out last week that the company couldn't secure the final round of financing and went the way of the Dodo bird.  Plan B.  I went out and bought the DJI Phantom 3 drone this week.  I think that it will provide some really cool vantage points to the golf course.  I have had it out of the box and up in the air twice now trying to learn how to fly.  I have attached some of my amateur footage below.  Enjoy!

Irrigation system update 1-20-17

Well the first part of 2017 has not been kind to us between the rock and the rain.  Last night we got 1.5" of rainfall onto an already saturated golf course.  The last 8 months have truly been feast or famine with regards to precipitation. 
On the plus side we are officially making the flip from front nine to the back nine for golf play tomorrow.  Unfortunately, we are forecast to get 0.5" of rainfall both days this weekend.  On the negative side we will be primarily Cart Path Only for the next 2 months.
We started piping on the front nine this week.  We have run into some rock on #8, as expected, and it has slowed the main line progress a little.  On the flip side the heads and lateral lines have been installed on #8 and most of #9.  The 2nd 10" main line that goes by the practice green got stalled by a big rock that we were not expecting.
In the positive column we have the completed wet well which looks like a small rock mountain.  I am hoping to pour a pad on it next week.  That's just one step closer to installing the, still unnamed, pump station. 
Also, we got the first and largest road bore completed yesterday.  It is the main trunk line, 12", from the pump station to #13.  We have 4 more to complete. 
We changed some of the concrete entrances and exits to roadways.  They used to be a 45 degree curb and gutter to cart path.  Now they are a more gentle transition from road to path and vice versa.  Also, we have been repairing some areas of the path that were really bad in the past.
