Shad close to home

RALEIGH A 2-pound American shad hen danced along the Neuse River’s surface and spun line off a medium-action spinning reel like a spool of kite string at the other end of a steady Atlantic breeze.

The scene is most common toward the coast, but there’s no need to truck down to the coast to satisfy the saltwater fishing urge.

For a couple of weeks, American shad have been concentrating at the Milburnie Dam in Raleigh, nearly 230 river miles upriver from the Pamlico Sound.

“They’ve come a long way,” said John Ellis, a U.S. Fish and Wildlife Service biologist who spends many spare spring hours pursuing American shad for the fun of it. “We’re pretty high up in the watershed.”

The American shad is one of several species that have been able to reach their former spawning grounds ever since a downstream dam was removed 12 years ago.

An electroshocking survey conducted near the Milburnie Dam last week by N.C. Wildlife Resources Commission biologists turned up several dozen American shad and even a couple of striped bass, typical of spring sampling for the past 10 years.

“It suggests that these fish are taking advantage of the spawning habitat in the upper part of the river,” said Bob Barwick, a state fish biologist.

Earlier in the spring, hickory shad, the smaller cousin of the American shad, also ran up the Neuse, the longest river that is completely within the state’s boundaries.

Ellis and several of his colleagues aren’t the only ones who get a kick out of fishing for shad during a run that typically lasts into May. Others use fly rods to cast brightly colored “junk” flies with success.

There’s no telling how many fish are kept, but state law allows a combination of 10 American and hickory shad to be kept per day, unless the angler is fishing the Roanoke River, where only one of those may be an American shad.

“They’re tasty,” said Ellis, who said he would like to see the limit for American shad lowered on the Neuse to help protect the species.

The state has considered doing so but has decided it against for now, Barwick said.

In North Carolina, American shad tend to spawn more than once in their lives. On the Neuse River, American shad could go only as far as the Quaker Neck Dam near Goldsboro until 1998, when the dam was removed, opening up 78 more miles of river.

The low-head dam had been built in 1952, and its removal reopened old spawning grounds primarily for American shad and striped bass.

The American shad population in the Neuse is viable enough that, until this year, state biologists removed shad from below the Milburnie Dam to be used in hatchery efforts to stock the Roanoke River, which has a struggling population of the species. Striped bass and hickory shad are more abundant on the Roanoke.

The collection stopped this year because, although there are still a few 4-pound females, considered good breeders, the numbers of bigger fish are dwindling in the Neuse.

“We’re worred about removing too many fish from the Neuse River,” Barwick said.

New water

A chance exists that more of the Neuse could be opened soon. An open comment period is being conducted by the U.S. Army Corps of Engineers regarding a proposal to remove the Milburnie Dam, which would add 15 free-flowing miles to the Neuse, making the Falls Lake dam the new dead end for migratory fish. The comment period closes April 22.

Carbonton Dam removal: A 6th Anniversary Look Back

Hard Hat News, 2006. Demolition of the Carbonton Dam, by Gwen Laird Pernie

In the Central Piedmont Region of North Carolina an effort is underway to restore 10-miles of the Deep River, a tributary to the Cape Fear River Basin. The river has been environmentally damaged for the past 200 years, when the first dam was built at Carbonton to power a mill on the riverbank. This $8.2 million dam-removal project, the largest ever of its kind in North Carolina, is also the first dam removal in the state to be done primarily for mitigation purposes. This project is the culmination of a five-year planning effort by Restoration Systems, LLC, of Raleigh, NC (owner of the dam) to re-establish the native aquatic ecology of the Cape Fear River Basin to gain “mitigation credits” under the North Carolina Ecosystem Enhancement Program. It was planned and is being implemented in close coordination with multiple county, state, and federal regulatory agencies. The dam is a former hydropower generating facility that is licensed under the Federal Regulatory Energy Commission. Site contractor for the project is Backwater Environmental of Pittsboro, NC, a subsidiary of Osborne Company General Contractors of Eden, NC. Osborne will handle the physical demolition and heavy work of the project, while Backwater will handle the earthmoving, grading, site restoration, and softer work. Restoration Systems retained Milone & MacBroom Inc. (MMI), of Cheshire, Connecticut and Greenville, South Carolina to investigate the existing dam and assist with agency permitting, and to design the removal strategy, prepare construction documents, and handle inspection during demolition. MMI is also designing a future public recreation park that will occupy the south riverbank at the dam site. According to Ken Kloeber, branch office manager of MMI’s southeastern regional office in Greenville, the most challenging aspect of the project was to design a dam removal sequence and methodology that will get heavy equipment in and out of the river quickly. “The challenge is to minimize the exposure of the removal operations on the Deep River system and the aquatic critters that this entire project will benefit,” Kloeber explained. “We wanted to avoid short term effects while accomplishing the greater good in the long term.” “An additional challenge was that much of the planning involved working with and getting approval from many county, state, and federal agencies–sometimes with overlapping authorities–on a fast-track schedule,” Kloeber continued. “Hydropower dam demolitions involving FERC approval typically take years in the planning and design stage. With the owner, contractor, and agencies cooperating, this one took a matter of months.” “Every dam removal is unique because no two are constructed the same,” Kloeber said. “We had to first evaluate and understand the structural components of the spillway and the powerhouse before designing the demolition methodology and sequence. It’s typically easiest to demolish dams in reverse order of their construction sequence.” “The planning of the particular project has been especially interesting because we were able to locate original 1921 construction photos of the powerhouse and spillway in their de-watered state, which gave us insight into how the facility was constructed,” Kloeber stated. “It literally painted a picture of what was hidden under the water, and allowed us to anticipate in order to save time.” “Typically, dam removals involve starts and stops as structures are uncovered and new situations need to be assessed, Kloeber said. “Having the right information and evaluations of the structures up front has allowed this demolition to proceed very smoothly. To the credit of Restoration Systems, the owners recognized the need for adequate investigations right away, and they provided us the resources to make that happen.” “Because of its age and type of construction, the Carbonton Dam is eligible for the National Register of Historic Places,” stated Kloeber. “So, Restoration Systems has taken extra care to preserve the history of the structures.”

Thar’ She Blows: Condit Dam goes down ugly in Washington State

As readers know, RS loves blowing up old, useless dams. And apparently so does the federal government. Look here at the Condit Dam recently breeched by the U.S. Fish and Wildlife Service to restore salmon waters in Washington State.

In North Carolina there is much gnashing of regulatory teeth and pulling of agency hair regarding the potential for a dam removal to make the water “turbid” (muddy) for some time during removal. As a result, and with some justification, RS dam removals have been managed with very little sediment released.  We drain the bathtub slooooowly.

Out West this did not appear to be much of a problem. My educated guess is that the sediment release pictured here at the Condit Dam would be considered “catastrophic” in the Old North State (by the same federal government that pulled the plug on Condit).

Each dam removal has its own special constraints and trade-offs. And I do not begrudge the federal sponsors their ability to break a few eggs when making an omelet of the White Salmon River. But it is amazing how one procedure can be employed in one area — and considered horrific in another.

In Fight Over Dam Sides Ask: What’s Natural?

RALEIGH For more than a century, Milburnie Dam has stood 16 feet high in the middle of Raleigh, a stone wall that interrupts the Neuse River like an aquatic comma. Above it, motorboats troll through deep water; below, fishermen wade around a pounding waterfall.

Now a Raleigh firm that does environmental work wants to tear out the privately owned dam and let the Neuse flow freely, removing the only man-made obstacle between Falls Lake and Pamlico Sound. Doing so, they say, would bring shad and other fish further upriver and improve the water quality by speeding up a slowed-down Neuse.
