Reminder:  When signing your landscape maintenance contracts for the Spring, please ensure that your landscape provider is using phosphorus-free fertilizers. Rainwater runoff containing Phosphorus causes adverse and irreversible effects to our lake and ponds.

Doubletree Residents, 

Beginning tomorrow, May 8, 2020, at 8:30 a.m., the current gate transponder system will be removed, and installation will begin on a new system. 

During this transition, all residents will need to utilize the guest lane at the front gate.  We understand this will be an inconvenience; however, the safety and security of residents is our priority.

Please monitor your email and/or the Doubletree website ( for updates as to when your new transponders will be ready for pick-up.  If you know someone not receiving email updates, please ask them to contact our office so we can add their email address to the distribution list. 

Thank you for your patience during this time.  We know everyone is looking forward to a fully functional system. 


  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
