News and updates..............

January 17, 2008

Come and see us at the West Kentucky Boat & Outdoor Show in Murray, Kentucky. We will have a booth there for the duration of the show (January 18-20, 2008)

Also, we will be at the Paducah Boat show the following weekend (January 25-27, 2008)

Patrick Hahs of Kentucky HydroGrafx will be presenting a seminar titled "Sidescan Sonar -- Uses for a typical Fisherman". The subject will include a basic understanding of conventional sonar and why sidescan sonar is so different and useful for the relatively shallow lakes we fish.

The creation of sidescan sonar imagery by Kentucky HydroGrafx continues to be very useful for many that visit KY and Barkley lake in pursuit of bass and crappie, and with Humminbird "SideImaging" units readily available, more have the ability to sidescan areas they want to know more about. Tips will be provided on how to use this technology for the most benefit.

The Sidescan data for the East Side Bays South is now ready for purchase. I have forwarded the information to TN Outdoor Sales for addition to their product list.

The form for mail-in orders is already updated. Click Here

We are currently scanning the TN Trio area of Kentucky Lake and plan to expand further upstream into the TN portion of KY Lake throughout this Fall. Barkley lake will also get attention when we start scanning the Barkley Lake NW area.

June 7, 2007

We have completed what is named "Kentucky Lake Northwest Sidescan". This includes the area originally topo and 3D mapped, but has been expanded from 1800 to 3000 acres in size.

A large portion of the expansion includes what the Sledd Creek embayment near Kentucky Lake Dam. Other areas expanded include the flats in the backs of the smaller bays with the area.

In our email notices from now on, you will have the option to unsubscribe from the notification list if you prefer to view our news on our website.

Mapping activities in the immediate future will include finalizing the East Side South data for release, then working further upstream in the Tennessee portion of Kentucky Lake.

The most recently completed sets other than the new KY lake Northwest include Eddy Creek Sidescan and Donaldson Creek Sidescan (both are on Lake Barkley).

We have added several sample images of the new Kentucky Lake Northwest Sidescan set. Jump directly to that page by clicking HERE. You can also link to it through the main product page for the new set below.

May 14, 2007

Kentucky Lake Northwest Sidescan data is finally complete. The first disks will be mailed out on Wednesday. The area of coverage was expanded from 1800 to 3000 acres. Most of the additional area includes the upstream end of Little Bear Cr. and the newly added Sledd Creek.

There are several that have prepaid for the imagery and they will be first out the door. More info to come in the next couple of days............

Donaldson Creek Sidescan is now complete!

January 13, 2007

Eddy Creek Sidescan data is available.

September 9, 2006

Coming soon..... new/updated products are in the works after a busy field season. We have been working on 4 different project areas this Spring/Summer. All of these are sidescan updates for existing areas. It's been tricky balancing wind/weather conditions along with night-time boat traffic.

The areas to be released this Fall include sidescans of Eddy Creek (Barkley), Donaldson Creek (Barkley), KY Lake NW, and Ky Lake East side bays south. Data collection activity status is as follows: Eddy Creek (90%), Donaldson Creek (95%), KY Northwest (35%), and East Side South (60%). Eddy Creek will likely be the first new release hopefully in early October.

Other news... We have a new survey boat that will allow all-year mapping work. I will post a few pictures of the boat soon. Excessive wind and/or freezing conditions will be the only deterrent to data collection activities from now on.

Sidescan Sonar has been used since 2003 to detect woody structure in some of the Bays on the LBL side of the lake, and also including Big Sandy and Blood River, and Jonathan creek. It has been an "eye opening" experience to learn where structure exists and how much is commonly overlooked by both shoreline and open-water fishermen.

This is a picture of the Sidescan Sonar. It is 30" long and weighs approximately 30 pounds.

 

Below are 2 stake beds or similar manmade structure. The square appearance reveals a major clue that it is not a natural feature.

This is a location in Big Sandy near a moderate slope into deeper water. White dots have been placed on what is likely natural stumps. I doubt that whoever placed the structure, knew there were 30 (or more) other structural features less than 50 yards away.

The image above represents 0.9 acre. The width of the image is just under 200 feet.

Above is a submerged boat in Blood River. It is 14 feet in length. Notice the sonic shadow of the boat on the bottom. Other unknown structure exists off the front end of the boat. August 2004

 

High resolution topographic imagery is available for key areas in Kentucky and Barkley Lakes

Kentucky HydroGrafx topographic maps have contour intervals of 0.5 - 2.0 foot and all sets are provided on CD-Rom.

Scans of popular paper navigation charts are also available if you are needing digital images of the entire lake.

A Tutorial section has been added to give you some hints and ideas on how to use GPS mapping software with digital images. Enter the site and choose "Tutorial" in the index.
