Event Details

Join Mile High Multisport, LLC in the tranquil setting of Grant Ranch to improve your open water swimming skills. 2014 represents the 6th year we have been welcomed by the Grant Ranch Community. Athletes can work on their open water swim stroke, sighting and transitions in preparation for the upcoming race season.  There is no other venue in Colorado which provides an environment which includes a marked course, showers and a lake free of motorized boats. Additionally, we offer swim clinics and swim races.  We have expanded our race series this season and will host two swim races this year.  One on May 25th and one on July 5th.  Check the swim race series link after the first of the year for more information.


You do not need to be a client of MHM or any other organization to swim in the lake.  We welcome all clubs and other coaching services.  You are not required to be a member of COMSA to swim in the lake, we are self insured.

Swimming is open to the general public during the times listed below.  Children under the age of 18 must have a current USAT membership card AND approval prior to swimming. (Parents will need to complete a special waiver.)

Open Water swimming is hosted by Mile High Multisport, LLC.  Please DO NOT call the Grant Ranch offices asking for information on open water swimming. ALL INFORMATION PERTAINING TO SWIMMING IS LOCATED ON THIS SITE.  I know there is a lot of information on this page but please read everything and you will have all your questions answered. Thank you in advance for doing this!!  

  •  For Liability reasons the person purchasing the ticket must be the user.  There is an online waiver associated with the purchase of your ticket which must be acknowledged by the ultimate user of the pass. 
  •  Swimming outside of posted hours is considered trespassing and strictly prohibited
  •  Please do not clean your wet suits in the locker rooms (clean them at home or use the hose when available)
  •  Please rinse off any muddy feet with the hose located next to the soda machine
  •  No admittance to the water within 30 minutes prior to closure.
  •  Wet suits are NOT required
  •  Swim partners are strongly encouraged but not required. There are no lifeguards on duty at any time.  
  •  The Temperature of the water changes on a daily basis. We don’t measure the temperature. The lake is only 12-28 feet deep so it warms up quickly. PLEASE don’t write or call and ask what the current temperature of the lake is.
  •  Respect the community and residents at all hours. Remember, residents live adjacent to the lake and voices carry. When swimming in the early morning hours, PLEASE be respectful of the residents trying to sleep nearby.
  •  We are a swim at your own risk lake. We provide safety kayakers on most weekends  and some week nights.  There are no lifeguards on duty on the water at any time. You must be adequately prepared to swim in open water. If you can’t swim at least 750 -1000 yards in a pool without holding on to the sides then you probably aren’t ready to swim in open water. We encourage swimming with partners, especially for those who are new to open water swimming or not comfortable swimming in open water. You MAY swim close to the shore line if you are unsure of your abilities. A limited number of Safety aides are provided free of charge. (first come first served)
  •  You MUST WEAR A LIGHT COLORED CAP. CAPS WILL NOT BE PROVIDED AS THEY HAVE IN YEARS PAST.  (Dark Blue and Purple aren’t light colored caps) No light colored cap, no admittance to the water. This helps other swimmers and lake users see you and this is written in the terms of our contract
  •  There are no motorized boats on the lake (other than the marina safety patrol boat)  there may be residents sailing from time to time (this is very rare).  If you see a boat on the water please be vigilant and yield when applicable.  Chances are you will see them before they see you.
  •  If you are riding your bike post swim DO NOT leave your car in the parking lot.  The Grant ranch community uses the pool when we are finished and needs the parking spaces.


  •  Weekend Swimming Opens: Saturday, May 17, 2014 and Concludes on 8/31/2014
  •  Week Day Morning  and Evening Open Water Swimming: Begins Wednesday, JUNE 4TH, 2014 (morning) Thursday, JUNE 5th (evening)  and will end on Friday before Labor Day weekend. (8/29).


  •  Annual Pass:  $135  (No sharing of passes)
  •  10 Punch Pass: $110 (Passes do not carry over from year to year, No sharing of  passes)

Once you have registered please bring your ticket receipt to the lake.  You will be provided a pass which you must bring with you each time, along with a photo ID.   If you don’t have your pass, you can’t swim. We will not have lists of participants as we have in years past   Photo ID and your ticket are required every time.  Don’t assume the person working registration will know you. 

Monitors will be informed, no pass and ID, no swimming (It’s a liability thing). IF YOU PRINT YOUR ONE DAY PASS MULTIPLE TIMES, WE HAVE A SYSTEM IN PLACE TO CATCH YOU. Someone tried that last year and was caught.  Monitors will keep your pass and return it to you when you exit the lake.  (This is our way of verifying entrance and exit of everyone from the water)


On weekday mornings and weekends, parking is not an issue.  On some week nights, parking will be difficult since the residents will also have use of the facility.  If the lot is full, there is additional parking at the school located 1/4 mile south on Grant Ranch Blvd.  If you park in the adjoining neighborhoods, please be respectful of the homeowners properties and neighborhood.  If you park on the street please pay attention to the “no parking” signs. .  DO YOUR PART AND CAR POOL so we can get more people in the lake.

    • PLEASE NOTE, there will be Youth swim meets on June 7th, 28th and July 12th.  We WILL be allowed to swim, but parking will be difficult on those days. Parking at the school 1/2 mile South on Grant Blvd and walking to the venue is a good idea.

2014 Grant Ranch Buoy Layout


The lake will be closed if threatening weather is in the vicinity.  Please do not call MHM or Grant Ranch to ask if the lake is open.  An announcement will be posted on our face book page once we have knowledge the lake is closing.  Sometimes we won’t know until we arrive on site.


  •  Sorry but no dogs are allowed on the premises (If they were, I would bring mine)
  • Children are welcomed but are NOT allowed in the water or the pool deck. On the weekends they may use the playground facility, but may not during the week when the residents are using the facility.  Please do not expect us to watch your kids while you are swimming.
  • If you are swimming week nights, PLEASE do not arrive early and go in the club house for any reason. We want to remain transparent.  Entrance to the lake week nights will be Via the Club House.
  • Please don’t call/e-mail me or Grant Ranch asking what the temperature of the water is.   The temperature changes from day to day.
  • The lake has race style buoys.  We do our best to keep the course marked each week, but if the buoys move over night we may not be able to reset them.
  • There are showers and locker rooms in the club house for our use. Please note the time you must be out of the facility and respect the Grant Ranch Community by adhering to these hours and respecting the facilities.
  • Please car pool whenever possible.

Miscellaneous reasons to swim at Grant Ranch (Bowles Reservoir)

  •  We have plenty of close in parking (It’s even paved)
  •  Showers/club house on site
  •  Private lake with professionally landscaped area
  •   No standing in the tall grass and weeds trying to get into your wetsuit
  •   Swim course with race style buoys
  •   We are self insured.  You don’t have to be a member of any organization to join us.
  •   We have our own monitors and safety kayaker(s) on the weekends
  •   Swim aides will be available for free use (while they last)
  •   Sure we have a lot of rules, but remember our situation is unique.  There is no other location in the state (or country that I’m aware of) that has our set up and relationship with the homeowners association. If we respect their rules we can swim in their lake.  It’s that simple.
