Anyone who believes didymo isn't spread by anglers is kidding themselves. Nobody took their drift boat / canoe to new zealand, and birds don't migrate there from the continental US. They didn't ban felt soles on a whim. Studies showed that it can survive in felt wading boots for MONTHS out of the water.

That said, the damage is done, and I will be very surprised if didymo becomes an issue on Pine Creek. It isn't a tailwater, gets fairly warm, and routinely has bottom scouring floods.

Didymo also doesn't do well in spring creeks, so central PA should be fine. There was a recent study linking blooms to phosphorus levels, I believe, so they may be able to control it somewhat based on that. We'll see.

I don't know if anyne is denying that it's spread by anglers...I think we're saying that's not the ONLY way it's spread, and some of those ways are out of our control.

I believe I saw that report regarding phosphorus levels. Perhaps this will provide a means of controlling an infestation. But clearly not enough people are aware.

Couldn't find anything on the PFBC site, but there is something on their Facebook page confirming that didymo has been found in Pine. That's the only "official" thing I've found so far, unless I missed something.

PFBC just released this announcement:

State Agencies Issue Alert
to Contain Invasive Species in Lycoming County


HARRISBURG, Pa. (July 11) – After confirming the presence of the invasive aquatic algae known as didymo, or “rock snot,” in Pine Creek, Lycoming County, anglers and boaters are reminded that cleaning their gear is the easiest, most effective means of preventing its spread to other waters.

“Our biologists have not seen any evidence of a full bloom of didymo in the creek or nearby waterways,” Department of Environmental Protection Acting Secretary Chris Abruzzo said. “This algae does not present a public health risk, but there is an ecological concern in terms of its future potential impact on the health of the waterway.”

In late June, DEP biologists were conducting routine stream monitoring in Pine Creek upstream of Waterville in the vicinity of the Hamilton Bottom Canoe Access Area, a popular recreational destination. Laboratory analysis of a sample collected using an algal net detected the presence of didymo in the form of microscopic diatoms, a finding confirmed by the National Academy of Sciences.

The Pennsylvania Fish and Boat Commission (PFBC) continued to urge anglers and boaters to take steps to prevent the spread of the algae.

“We may not be able to eliminate didymo from an infected waterway, but there are easy steps we can take to slow its spread and to prevent it from spreading to other waters,” said PFBC Executive Director John Arway.

“Didymo cells can easily be carried downstream and can be picked up by any items which come in contact with the infected water, including fishing tackle, waders, and boats and trailers. We urge anglers and boaters to ‘Clean Your Gear!’ before leaving a water body and entering another one.”

The discovery of the algae in a popular recreational area potentially increases the risk of its movement to other waters in Pennsylvania.

“Flowing through the heart of Tiadaghton State Forest, Pine Creek and its parallel trail are increasingly popular with anglers, boaters, hikers and other Pennsylvania residents and visitors,” said Department of Conservation and Natural Resources Acting Secretary Ellen Ferretti.

“The discovery of didymo has no immediate impact to the visitor experience on or along Pine Creek, but we ask all to remain vigilant in an effort to protect this invaluable waterway and other streams and rivers,” Ferretti said.

Prior to detecting didymo in Pine Creek, the alga was found in the Youghiogheny River watershed in Fayette County, in the West Branch and main stem of the Delaware River, and in Dyberry Creek in Wayne County.

The PFBC recommends that anglers allow exposed equipment to completely dry before entering new waters. After equipment is dry to the touch, allow it to dry another 48 hours, the commission suggests. Thick and dense material, such as life jackets and felt-soled wading gear, will hold moisture longer, take longer to dry, and can be more difficult to clean.

Soaking equipment in hot water containing dishwashing detergent (two cups of detergent for every two and a half gallons of water) for 20 minutes or more also will kill didymo and some other aquatic invasive species.

Cleaning boats and equipment with hot water (maintained at 140 degrees Fahrenheit) by pressure washing or soaking is another effective method. If hot water is not available, a commercial hot water car wash also makes a good location to wash boats, motors and trailers. At the other end of the temperature range, freezing items solid for at least 24 hours is effective. If cleaning, drying or freezing is not practical, please restrict the equipment’s use to a single waterway.

Didymo is not a public health hazard, but it can cause ecological damage by smothering other organisms which also live on the riverbed and support the food web for the resident fish community.

The algae, whose scientific name is “Didymosphenia geminata,” has colloquially been called “rock snot” because of its appearance. When squeezed nearly dry, the algae, generally tan to beige in color, actually has the feel of moist cotton or wool.

Maybe this isn't a bad idea (seriously).

It'd be cool if the fly shops up there - Big Meadows, Slate Run Tackle, and McConnell's - could set up gear wash stations at their respective shops, and/or streamside.

Wouldn't cost much to set up, and they could provide educational material and advise to help prevent angler spreading of this invasive.

It'd also promote visiting these shops, and benefit them from the increased exposure. Working together on this would show a united front in protecting the watershed, and help prevent the spread of didymo to other watersheds.

Sandfly would be uniquely qualified to set up a waterfowl washing station too.

Good idea, Ed. The Casselman down here has bootwash stations streamside. Why not let the sponsor get some free advertising for the expense and time? The salt basins need to have a container of salt, so you can make sure the water in the basin is actually briny enough before washing off.

Great idea Ed!

it's a shame a FF company doesn't come out with a kit. you'd think some of these people would be all over that.

of course I guess you would be inadvertently assuming a certain amount of liability by selling that...Dam!

It won't thrive in Pine. Pine gets too warm. If it was in Pine above Galeton, then I think there could be a real issue.

But it will thrive in the tributaries, thus it will be spread through the wayershed unless the resposible agencies take inmediate action to prent it's spread.

H-A says a wash station wouldn't cost much.

I don't understand. The methods given to eliminate this stuff from your gear look neither easy nor cheap.

1. The PFBC recommends that anglers allow exposed equipment to completely dry before entering new waters. After equipment is dry to the touch, allow it to dry another 48 hours,

Not going to happen.

2. Soaking equipment in hot water containing dishwashing detergent (two cups of detergent for every two and a half gallons of water) for 20 minutes or more also will kill didymo and some other aquatic invasive species.

Two Cups of detergent is more dish washing detergent than I have used in the last four years @ camp. How do I keep enough water to soak 4 sets of wader/boots hot for 20 mins? Is the hot water from the hot water heater hot enough? I usually have running water in the camp until late May, how do I do it without running water?

3. Cleaning boats and equipment with hot water (maintained at 140 degrees Fahrenheit) by pressure washing.

A cheap hot water pressure washer is $1500.

4. a commercial hot water car wash

Is there one of these in the Pine Creek Vally?

5. freezing items solid for at least 24 hours is effective

Not an option.

Can someone explain how easy, cheap and effective solution?

Shortrod,

I understand your conundrum. When basing out of a camp with no running water or electricity, your options are limited. On extended trips I have the same problem.

I would think your answer lies in harsher detergents. Clorox will do it. Just gotta be careful not to ruin your gear. Rinse your waders in it, then with water. Rinse your boots, then with water. If you wear felts, leave an inch or so in a plastic tub, only deep enough to hit the felt but not soak the uppers. Set them in there for a little while, then rinse with water.

That's about all you can do, if say, fishing multiple streams in the Pine Creek watershed. When you fish 2 or 3 streams a day for 3 days straight, you just can't have that many sets of gear to trade out and allow to fully dry.

Saltwater may be a preferred option to clorox. Less harsh on fabrics. Harsher on metals, so be sure to rinse the eyelits of your boots and such well with fresh water.

A brine washing station was exactly what I was thinking of. They're being set up at other places where Didymo is found.

Are they effective? Dunno, but the educational aspect of these stations would likely raise awareness of the problem - at least get people thinking of possible better options for cleaning gear.

Here's an article that explains more about it from the Yough.

The TU chapter that built these stations stated the stations cost $50 or $60 bucks (with some donated materials). The upkeep would be the worst part, I would think.

It's better than doing nothing, IMO.

Heritage, I think these stations are more of a feel-good effort than an effective cure. But as you noted, they are educative. All the boot-washing in the world will not stop this menace from spreading. I am not even convinced it will slow it down. But,... I washed my boots when I saw one, for what that was worth.

Maryland has had wader wash stations on its blue ribbon streams for at least the last several years. Regrettably, I have never seen anyone use them and many have fallen into disrepair in the last couple years. I do agree, however, that these stations can play a good role in education as they're well marked with signs and pictures of didymo.
