Wachusett Reservoir, Boylston, MA 01505


Location Information


The Wachusett Reservoir is the second largest body of water in the Commonwealth of Massachusetts and is a link in the chain of water supply for the City of Boston and 50 other cities and towns in Eastern Massachusetts. The MWRA manages the reservoir (including the water level), while the Department of Conservation and Recreation (DCR) stewards the surrounding lands. The Wachusett and Quabbin reservoir system are widely regarded as one of the best drinking water supply systems for a major metropolitan area in the United States, and the story behind the development, construction and use of them is fascinating. The Wachusett Reservoir holds 65 billion gallons of water and is up to 117 feet deep. Fishing is allowed in most areas, but swimming, boating, and other uses of the water are strictly prohibited. A network of fire roads and trails provides ample hiking opportunities around the reservoir. 

Users of the Wachusett Reservoir area should be familiar with the rules and regulations for the area:

This KMZ map is set to Draw Order 32 so it will show 'beneath' the primary map on your Garmin KMZ-compatible GPS.  

Note that due to the wide coverage area of this map, it is actually 4 tiles. Keep that in mind when placing this on your Garmin GPSr - even though this is one KMZ, the number of tiles is limited to 100 across all the KMZ files loaded on most Garmin GPSr models (500 tiles if you have a Garmin Colorado).

The image on the left in each row below is from a Garmin GPSMAP 78sc with no other maps displayed. The image on the right in each row below is from the same device with the Garmin 24K NE series TOPO maps displayed.
