About RLMC

Rainbow Lakes Maintenance Corporation


Rainbow Lakes is a community consisting of 1,200 acres of natural homestead surrounding two lakes in southern Gratiot County, Michigan.  Big Rainbow is a man-made reservoir lake covering 304 surface acres and twisting 4.5 miles.  It is a private, all-sport lake with depths reaching up to 35 feet.

Little Rainbow is a smaller branch-off lake that is for non-motorized watercraft only.  Both lakes are part of the Upper Maple Watershed. Water flowing from Big Rainbow via Pine Creek and then the Maple River provide a major source for the Grand River.

Rainbow Lakes Maintenance Corporation (RLMC) is the governing body that oversees the lake and its community of approximately 750 property owners, 80% of those being full-time residents.

RLMC is a private, non-profit corporation that acts as the governing body for the lake and its community. It consists of a nine-member Board of Directors who interpret and enforce the member-approved by-laws. The Board operates within a predictable budget based upon a mandatory, annual fee charged all property owners.

RLMC board meetings are held at the lake office (4353 Rainbow Lake Rd.) on the 2nd Wednesday of the month at 7 p.m. Any property owner is welcome to attend. Member opinions and participation are important to the community’s success. The meeting agenda always leaves time to listen to suggestions or concerns.

As a part of Gratiot County, Fulton Township, MI we are also subject to their laws and ordinances. The link below will take you to the Gratiot County Department of Ordinances page where you can view all the applicable ordinances. In particular, we are often asked about the ORV Ordinance.

Much of the success of the Rainbow Lakes community lies with those individuals who volunteer their time and talents. 
Many hands make light work and that couldn’t be truer for our annual Spring and Fall lake work days. Spring time involves common area clean-ups as well as bringing out summer supplies. Likewise, the fall has a clean-up as well (leaves) plus the pack-up of those same supplies.
Even if you cannot physically help, workers enjoy drinks, snacks and cookies provided by other volunteers.
Watch the newsletter and website front page banner for exact dates and times. 
Additionally, many lake members head up more permanent areas of responsibility with volunteer positions like those listed below.

Rainbow Lake Beaches

Rainbow Lake has many lakeside parks and beaches scattered around the lake for property owner use and enjoyment.  The main beach being the largest offers bathrooms that are open in season, a sand volleyball court, and extra boat docking piers in addition to the lake’s only boat launch.

Beaches offer a great place for small children to safely enjoy the water as they have marked and bouyed swim areas. Picnic tables are available for eating and gathering.  Outside visitors are welcome to these areas as long as they are accompanied by a RLMC property owner. If you do make use of these areas, please be courteous and clean up before you leave.  

Water Health & Animal Life

As lake residents we are all concerned about our water’s health and the health of the animal life living in and off of its waters. As a man-made reservoir and lake community, RLMC monitors the lake waters on an annual basis.

Public Sector Consultants have completed a document on E. coli contamination that is available for you through the link below. Central to this effort was convening a work group to explore the issue and make recommendations for reduction. Rainbow Lakes thanks John Pohl for representing our community as a member of this work group. We are proud to say that our lakes continue test at acceptable levels of this bacteria contaminate. You can access the full report here.


In recent years Rich Blemaster has spent considerable time criss-crossing the big lake.  Not fishing, he was mapping the lake bottom and its features using sophisticated sonar mapping equipment. The fruits of his efforts are now available in the form of lake bottom depth contour maps like the ones below. The full map can be added to certain fish finders made by LOWRANCE fishing electronics. (visit www.genesismaps.com to see if this is available to you.)

Office hours are currently limited due to the COVID-19 restrictions. We try to be available in the office on Monday and Wednesday mornings. Please call before you come out to make sure that someone is here to assist you.
