The Virginia Shad Cam is back online!
Tony, thanks for the update, been wondering what happened to them, I've got some great pics off of that site.
Thanks Tony! I forgot about the Shadcam, I sat here for way too long last year watching it! Looks like I will be doing it again! :wink:
This thing kept me occupied a bunch last year.
I'll be fishing for these very shad come Friday! I can't wait.
i watched it for a bit but didn't see anything. thats kind of cool.
Jason, yeah, some times it takes awhile, but I've saved some great Catfish pics from there, you'll see gar, carp, all species of fish.
What the he11 am I looking at? Looks like concrete. Which way is up? :tounge_out:
If a fish would show up for once, might get my bearings but none so far!
I've had more fun watching paint dry.
No offense but it's the truth and watching paint dry ain't that much fun itself. :smile2:
keep an eye on the shad cam, as the fish migrations start, you'll see them start cruzing through. Bass, cats, gar, eels, shad, snakes, you name it.
All I get is a screen and on bottom says Shad Cam will refresh in 9 sec ,counts down then does it over and over and over.Never no pictures. Oh well.
I've watched it for a few minutes and didn't see anything, but that's pretty interesting, Tony. I plan on checking it out again when I have more time for it. I wonder if there are other cameras like that somewhere???
What you are viewing:
In Colonial times, Virginia's waters teemed with shad and herring. Scientific and anecdotal evidence shows that American shad once migrated up the James River to sites near its headwaters at Eagle Rock. Early European settlers made particular reference of these numbers, noting that "[t]he rivers abound with fish both small and great. The sea-fish come into our rivers in March...great schools of herring come in first; shads of a great bigness follow them" (Alexander Whitaker, 1613). The economic value of the shad fishery in Virginia waters increased steadily throughout the 1800s and peaked in the early 20th century. However, the 1800s also brought about the construction of many large dams, including Bosher's Dam in 1823, for water power for grist mills, canal systems and other developments of the Industrial Age. These dams barred migratory fishes from their historic upstream spawning habitats, reducing the number of fish that returned each spring. When the American shad fishery crashed in 1994, a moratorium was placed on their harvest. While such corrective actions can be implemented immediately to help restore declining fish populations, removal of dams and the return of fish to hundreds of miles of spawning habitats can take years to accomplish.
The work of creating new fish passages in the James River began in Richmond in 1989, when Manchester and Brown's Island dams were breached with explosives. Since the Belle Isle Dam had been "naturally" breached during a prior storm, the next challenge was at Williams Island Dam. A 30-foot wide by 2.5-foot deep notch was cut into the dam in 1993, opening another 2.6 miles of spawning habitat to the base of Bosher's Dam. While these breaches, or gaps, took a great deal of planning and financial support from many partners, moving fish around Bosher's Dam would present the most significant challenge to date on the James River.
While short notches or gaps had been used successfully in the other Richmond dams, passing migratory fish around the 10-foot high Bosher's Dam required biologists to consider a much more substantial fishway. After careful evaluation of the site and consultation with other experts, biologists and engineers determined that the most appropriate structure would be a "vertical slot" fishway.
As with any fishway, one of the primary objectives is to provide smooth flowing water that attracts fish away from the frothy turbulent waters flowing over the dam. Fishways are positioned and designed to maximize this "attraction flow," guiding fish into the fishway. In some passage facilities, such as this one, resting places must also be provided to prevent the fish from tiring out before they reach the upper end. Once fish enter the Bosher's fishway, they negotiate their way through a series of 13 "baffles" and resting pools as they make their ascent. The term "vertical slot" refers to the 16-inch gap in the baffle wall that divides on pool from the next. Fish can easily swim through the vertical slots, gaining 9 inches each time they move from pool to pool. Near the upper end, they pass by a 4-foot wide by 7-foot high counting window before exiting the fishway into the river above the dam. A webcam has been stationed at the counting window to give visitors a peek at this incredible journey. At the Bosher's fishway, there is also a trap near the window that allows biologists to sample fish as needed.
Throughout this project, a small but vital 3-agency team continued to keep the vision alive. The James River Association, without whose efforts this project would not have been accomplished, spearheaded the fundraising efforts. The Department of Game and Inland Fisheries continued to coordinate the project and obtained (and matched) several federal grants. The City of Richmond the current owner of the dam also provided funding and personnel to the initiative. Ultimately, funding for the $1.5 million fishway was secured through grants, donations, and contributions from federal, state, city, and county agencies; corporations and foundations; and citizens... an excellent example of public-private partnerships!
* The white background is 30 inches from the wet side of the 5-inch thick viewing window.
* The camera lens is about 36 inches from the dry side of the window.
* Fish position between the background and the window affects size estimation (forced perspective). Using background marks will tend to overestimate actual size while using glass marks will tend to underestimate actual size. Average the measurements for a rough estimate.

Tony, there's a problem with the Bonneville site, when I hit the link, a page comes up say's there's a problem with their security certificate. I had the same problem with them last year?
I get an error stating that the security certificate author is unknown. Just mark accept and click ok and it will load fine.
I love watching the shad cam when the fish are running. Lots of shad, and an occasional catfish.
I am tempted to see if I can avoid the crowds downriver, and fish the slack water area that funnels the fish in to the fish ladder?
Thanks that is a cool site.
