Dear Doubletree Residents,

I would like to inform you that there have been couple changes made recently to the Doubletree Lake Estates Board of Directors.  Brett Jury has resigned from Board of Directors.  Due to Brett’s personal and business needs, he and his family have listed their home and have moved out of Doubletree.  We would like to thank Brett for his contributions and commitment to Doubletree HOA over the last several years and wish him and his family best of luck on their new venture.

Per the Doubletree By-laws, Board vacancies are filled by a majority vote of the remaining directors.  The Board met and unanimously voted in favor of offering Lori Chalmers the opportunity to fill the vacant position.  Upon meeting and discussing board member roles and responsibilities with Lori, she graciously accepted to volunteer her time and talents for the betterment of our community.  Lori will serve out the remainder of the vacant term (Brett Jury’s) and will also serve as the liaison to the Social Committee.  

Her contact information will be added on our Doubletree website www.DoubletreeHOA.org.

Please join me in welcoming Lori to the Doubletree HOA Board!


9/30/2019 Many thanks to the Social Committee for their volunteerism helping to collect donations going to local schools.  They were able to collect even more than last year!



  1. E-Coli test results--  we continue to regularly test for e-coli, as we have done for years.  Our past and present tests continue to show excellent results.

  2. Blue-green algae – On 6/28 Lake & Pond biologist treated specific areas around the tunnel and backbay inlet.  They were not alarmed by anything they saw.  Please continue to avoid any blooms that may occur and inform 1st American.
  3. Swimmers itch – residents may treat this condition by purchasing copper sulfate crystals (Tractor Supply, click to view) and applying it along your shoreline…it will help eliminate any symptoms.  Per Indiana law a resident along a lake shoreline may treat 625sqft of water.  After you apply wait for the crystals to dissolve before swimming.

    1. Other ​suggestions:

      1. Apply sunscreen ​

      2. Rinse off after swimming

      3. Use a swim shirt



Dear Doubletree residents, per our previous e-mail communications, we are fully aware of the blue/green algae at couple locations around our Lake.  We have been in contact with our lake and pond biologists who continue to closely monitor the situation.  At this point, no remediation activities are required.  These localized areas of blue/green algae shall be avoided and the rest of the Lake is deemed safe to swim in.  If you have any questions regarding the condition of the lake, please reach out to Mike Bottos at 1stAmerican Management Co.



Doubletree Residents,


The lake biologists that treat our lake have recently discovered Cyanobacteria (Blue Green Algae) that has bloomed. It is present from the most western no-wake buoy near the tunnel to the back bay west of the tunnel.  According to the Indiana Department of Natural Resources, humans and pets should not swim or drink the water in those areas.  You should avoid direct contact with the algae and shower with warm soapy water after swimming, wading or skiing when near a bloom.  Please see the link below for more information from the DNR on Cyanobacteria.



More details:

—due to the unusually heavy rains most lakes are having blue green algae issues

—the blooms should go away on its own

—if you see a bloom, see pictures, (looks like pea soup or paint) avoid swimming in those areas. The lake biologists this week noticed it is near the tunnel and in the back bay west of the tunnel. 

—swimming is safe in areas of the lake that don’t have blooms

—boating and fishing is still allowed throughout the lake

—please note the other advisory info from the DNR through their link
