Today Quabbin Reservoir and Reservation play host to thousands of visitors each year seeking to take advantage of the numerous natural recreational opportunities existing within its borders.

Though a series of strict regulations are in place, anglers from across the region descend upon both the shoreline areas surrounding parts of Quabbin Reservoir. Even more Quabbin fishing enthusiasts launch boats onto the Big Lady’s pristine waters in pursuit of over 20 species of freshwater fish.

Most of us can recall past days on the water and compare the more prominent details of earlier days to current conditions.

Although many of the methods used and patterns encountered may be remembered, the subtle details that actually contributed to fish catching success during previous trips usually remain a mystery.

Why Do Fishing Professionals Become Successful?

So how do the professional fishermen adjust to ever-changing conditions during tournaments so rapidly?

Simply by reviewing the key factors of previous fishing trips to set the foundation for the upcoming days on the water!

Most touring pros keep a fishing journal to help recall the prior information before leaving for their next toruney.

When properly updated, the log becomes a complete history of each day on the water. Every piece of infoormation including weather conditions; water temperatures and clarity; sections fished, structures and types of cover evaluated; etc. is recorded.

Starting Your Quabbin Reservoir Fishing Diary …

The log is formatted with a minimum of two parts: 1) the field log compiling info while on the water and 2) the permanent file kept in your home fishing workspace.

In the case of the field log, most everyone uses something like a small notepad with card-stock sheets and keeping it in a plastic bag with a pencil and short ruler to record data while out on the reservoir.

Recorded information usually includes the following data:

1. Date
2. Reservoir Fished (in this case the Big Lady)
3. Total Hours On The Water
4. Weather Conditions (indicate sun, full cloud, part cloud or rain)
5. Wind Direction and Strength
6. Temperature (air and water)
7. Time Fish Was Landed (indicate when fish was caught)
8. Fish Numbers & Measurements
9. Water Conditions
10. Type of Cover/Structure Fished — weedline, rocks, slop, pads, dock, etc.
11. Plug or Bait (include size and color)
12. Retrieve (fast, slow, finesse, etc.)

The office diary consists of a permanent record of the field diary along with more detailed records.  Most of the time photos and clipped sections of topographic maps are included with the permanent notes.  Since historical topographic maps are available, these are a great asset to include (see previous post).

The final result of your endeavors helps you be better prepare and remember all the keys of your Quabbin fishing locations and patterns!

Quabbin Reservoir 10-Ft. Bathymetric Map

Spread the love

A few years ago, mapping professionals at the DCRs Office of Watershed Management compiled survey data from the 1920s to create a geographically-referenced dataset to represent the bathymetry of Quabbin Reservoir.

Though the greatest care was taken during compilation of the dataset to facilitate an accurate depiction of Quabbin’s bathymetry (underwater topography), natural processes plus mapping errors mean some mistakes may exist. Therefore any map products derived from this or other similar endeavors should not be used for navigational purposes.

The GIS data files are available for download from the MassGIS Data Download area and anyone knowing some of the basics of GIS data processing can produce a map showing the lake bottom topographic contours as depicted below:

We used the dataset to produce a 1:32000 scale lake 10-ft contour map for Quabbin Reservoir that can be downloaded by clicking on the image above.

The map is provided in JPG format and measures 40 inches in length and 30 inches in width if viewed at a 100 % zoom setting and is archived in a Zip file to help with download speed.
