We are planning on floating the Upper C from Pumphouse to Radium on June 1-2. With the later run off than last year do u think it will be fishable or should we look elsewhere to float fish that weekend from Denver? I've only floated this section later in the summer for fishing but was hping to get into some salmon flies at the beginning of June.

Thoughts?

Thanks,

I am at the point where I have to replace my custom Oakley Monster dog with Vr28 polarizing lens with something else. The Oakley are still very HD for driving but starting to lose they performance sight fishing in a cloudy day or looking into shaded water.
Prior to buying the Oakley years ago, I had Costa Del Mar 580P Amber lenses in mind but opted to chose Oakley Vr28 Brown lenses instead.

Does anyone have any recommendations on the brands and lens color for sunny, bright and cloudy days?

this is a material that comes from many parts of the country... This is really beautiful stuff..making for a very durable grip if used solo...or just a super for butts or winding check areas...the smaller lines are very attractice as well of course...it does not require ant finish etc just like cork.

this is what I am doing on my special edition series bamboo rods now...at least parts of the grip finished off with BB...it is for sure more durable and compliments bamboo and natural cork excellent...

rather than try and manage the bark pieces individually in the glue up process to prep for the turn, I decided to make the bark up into sections that are compressed evenly and with solid glue connections. It is a lot easier for me to handle it...and guaranrtee a good joint everywhere...surprises mid way in a turn are devastating...a lot of work and time( and materials) can be lost if things arent right .

it can be bought too from the regular folks...mud hole etc in small sheets...8-10 pieces makes about an inch of ring.

after cutting the bark into 2" X 2" squares I take small 1X pine blocks the same size and used them to assist in clamping.After cleaning up the bark I soaked it and did a "dry" clamp up to get the fit good...then after a week I took it apart scrape them down and remove any loose material...a slight sanding, then glue them up with gorilla glue. They get clamped with a basic cabinet door bar clamp fairly tight...maintaning an even boundary on all sides is important. I cut the rough circle on my band saw and finish sanded the diameter w/ the drum sander. I made them in 1/2, 1, and 1 &1/2 inch rings...for accents , winding check dome on a reverse wells style or for the rear section on any grip...


I think this will really help out with the process...I am mixing these with cork in natural and some medium burn slices too for more accents...


Its a bit of work, but guarantees good connections and adhesion with this slightly unruly material...t ]]> Fly Rod Building silvertip8k http://www.theflyfishingforum.com/forums/fly-rod-building/320014-birch-bark-rings.html http://www.theflyfishingforum.com/forums/wading-equipment/320013-lacrosse-rubber-boots-fishing-hiking-wading-hunting-etc.html Tue, 21 May 2013 14:50:20 GMT US $50.00 (0 Bid)

Pictured here is a wind power project in eastern Oregon. Photo courtesy of BLMOregon.Enough Northwest wind energy to power about 85,000 homes each month could be stored in porous rocks deep underground for later use, according to a new, comprehensive study. Researchers at the Department of Energy's Pacific Northwest National Laboratory and Bonneville Power Administration identified two unique methods for this energy storage approach and two eastern Washington locations to put them into practice.

Compressed air energy storage plants could help save the region's abundant wind power—which is often produced at night when winds are strong and energy demand is low—for later, when demand is high and power supplies are more strained. These plants can also switch between energy storage and power generation within minutes, providing flexibility to balance the region's highly variable wind energy generation throughout the day.

"With Renewable Portfolio Standards requiring states to have as much as 20 or 30% of their electricity come from variable sources such as wind and the sun, compressed air energy storage plants can play a valuable role in helping manage and integrate renewable power onto the Northwest's electric grid," said Steve Knudsen, who managed the study for the BPA.


All compressed air energy storage plants work under the same basic premise. When power is abundant, it's drawn from the electric grid and used to power a large air compressor, which pushes pressurized air into an underground geologic storage structure. Later, when power demand is high, the stored air is released back up to the surface, where it is heated and rushes through turbines to generate electricity. Compressed air energy storage plants can re-generate as much as 80% of the electricity they take in.

The world's two existing compressed air energy storage plants—one in Alabama, the other in Germany—use man-made salt caverns to store excess electricity. The PNNL-BPA study examined a different approach: using natural, porous rock reservoirs that are deep underground to store renewable energy.

Interest in the technology has increased greatly in the past decade as utilities and others seek better ways to integrate renewable energy onto the power grid. About 13 percent, or nearly 8,600 megawatts, of the Northwest's power supply comes from of wind. This prompted BPA and PNNL to investigate whether the technology could be used in the Northwest.

Researchers at PNNL and BPA have identified a site they call Columbia Hills north of Boardman, Ore., on the Washington state side of the Columbia River, that could house a 207-megawatt conventional compressed air energy storage facility.Researchers at PNNL and BPA have identified a site they call Columbia Hills north of Boardman, Ore., on the Washington state side of the Columbia River, that could house a 207-megawatt conventional compressed air energy storage facility.To find potential sites, the research team reviewed the Columbia Plateau Province, a thick layer of volcanic basalt rock that covers much of the region. The team looked for underground basalt reservoirs that were at least 1,500 feet deep, 30 feet thick and close to high-voltage transmission lines, among other criteria.

They then examined public data from wells drilled for gas exploration or research at the Hanford Site in southeastern Washington. Well data was plugged into PNNL's STOMP computer model, which simulates the movement of fluids below ground, to determine how much air the various sites under consideration could reliably hold and return to the surface.

Two different, complementary designs

Analysis identified two particularly promising locations in eastern Washington. One location, dubbed the Columbia Hills Site, is just north of Boardman, Ore., on the Washington side of the Columbia River. The second, called the Yakima Minerals Site, is about 10 miles north of Selah, Wash., in an area called the Yakima Canyon.

But the research team determined the two sites are suitable for two very different kinds of compressed air energy storage facilities. The Columbia Hills Site could access a nearby natural gas pipeline, making it a good fit for a conventional compressed air energy facility. Such a conventional facility would burn a small amount of natural gas to heat compressed air that's released from underground storage. The heated air would then generate more than twice the power than a typical natural gas power plant.

The Yakima Minerals Site, however, doesn't have easy access to natural gas. So the research team devised a different kind of compressed air energy storage facility: one that uses geothermal energy. This hybrid facility would extract geothermal heat from deep underground to power a chiller that would cool the facility's air compressors, making them more efficient. Geothermal energy would also re-heat the air as it returns to the surface.

"Combining geothermal energy with compressed air energy storage is a creative concept that was developed to tackle engineering issues at the Yakima Minerals Site," said PNNL Laboratory Fellow and project leader Pete McGrail. "Our hybrid facility concept significantly expands geothermal energy beyond its traditional use as a renewable baseload power generation technology."

Researchers at PNNL and BPA have identified a site they call Yakima Minerals that is about 10 miles north of Selah, Wash., and could house an 83-megawatt geothermal compressed air energy storage facility.Researchers at PNNL and BPA have identified a site they call Yakima Minerals that is about 10 miles north of Selah, Wash., and could house an 83-megawatt geothermal compressed air energy storage facility.The study indicates both facilities could provide energy storage during extended periods of time. This could especially help the Northwest during the spring, when sometimes there is more wind and hydroelectric power than the region can absorb. The combination of heavy runoff from melting snow and a large amount of wind, which often blows at night when demand for electricity is low, can spike power production in the region. To keep the regional power grid stable in such a situation, power system managers must reduce power generation or store the excess power supply. Energy storage technologies such as compressed air energy storage can help the region make the most of its excess clean energy production.

Working with the Northwest Power and Conservation Council, BPA will now use the performance and economic data from the study to perform an in-depth analysis of the net benefits compressed air energy storage could bring to the Pacific Northwest. The results could be used by one or more regional utilities to develop a commercial compressed air energy storage demonstration project.

The $790,000 joint feasibility study was funded by BPA's Technology Innovation Office, PNNL and several project partners: Seattle City Light, Washington State University Tri-Cities, GreenFire Energy, Snohomish County Public Utility District, Dresser-Rand, Puget Sound Energy, Ramgen Power Systems, NW Natural, Magnum Energy and Portland General Electric.

Wednesday, 15 May 2013 11:54 PM


One of Alaska's most active volcanoes has erupted with clouds of ash and steam, and lava is flowing down its snow-covered flank, scientists said on Wednesday.

Pavlof Volcano began erupting on Monday and was still belching clouds, the Alaska Volcano Observatory said.

It has been emitting occasional dark clouds of ash and steam rising up to 20,000 feet (6,096 metres) and drifting toward the northeast, the observatory said.

The 8,261-foot (2,518-metre) Pavlof joins Cleveland Volcano in the Aleutians, which has been erupting off and on since mid-summer 2011.

Pavlof, on the Alaska Peninsula, is 590 miles (950 kilometres) southwest of Anchorage. The closest communities are Cold Bay, home to about 100 people, and King Cove, population about 940.

Pavlof last erupted in 2007, but it has erupted at least 24 times between 1901 and 1996, the observatory said.

Ash from Pavlof and other Alaska volcanoes could pose a risk to air traffic. But as of Wednesday, there had been no flight problems reported, said John Power, scientist in charge at the observatory.

Like many of Alaska's volcanoes, Pavlof lies along a major commercial airline route between Asia and North America. Generally, jets fly at about 30,000 feet (9,150 metres), and Pavlof's ash has not reached that level, according to observatory reports.

The lava flow poses a different risk.

"The concern is the hot lava melting large amounts of snow," Power said, and the result could be mudslides.

For now, the volcano appears to be putting on a show for its neighbors.

Residents of Cold Bay, about 37 miles (59 km) southwest of Pavlof, have reported an incandescent glow at night at the volcano's summit, Power said.

Meanwhile, Cleveland Volcano continues to emit heat signals, Power said. The last explosion at that 5,676-foot (1,730-metre) volcano was on May 6.
