Removal of a Dam in Soutwest Washington

One of the major solutions in reversing the decline of salmon is the removal of dams which block their passage to spawning grounds.  Most of us have read articles on the dam removal projects on the Kennebec River in Maine.  The link below will take you to very interesting video showing the October 26th breaching of Condit Dam on the the White Salmon River.

New York State Releases DEC SGEIS Regulations
 
Released On September 7 the state released its regulations for hydro fracking and gas drilling. There will be 3 public hearings, one in Delaware, one in Sullivan, and one in New York City. An index to its content with links to individual sections is available at the following link:

Brook Trout and the Results of Stream Improvements

The Smithsonian Magazine has a good article brook trout, the effect of non-native species, and the results that can be achieved by stream improvement.  Go to it with the following link:

Wappingers Watershed Study

Our chapter is working together with the Cornell Cooperative Extension watershed project to monitor the Wappingers Creek watershed and assess water conditions at various points in the stream along with its tributaries.  Water temperatures are taken on 24/7 basis using electronic "bottons" secured to the stream bottom and replaced each month.  These store temperature information which is read into a computer data base.  The chapter underwrote the cost of these devices.  Additionally, water flow and dissolved oxygen are measured, and water samples are collected.  This information, particularly with respect to tributaries, will help identify thermal refuges and will help us focus on projects that might maximize the availability of cooler water for trout, and thereby maximize the use of our resources in those areas where trout survival is most apt to succeed.  Other county streams will be studied in the future.  Below are two pictures taken during one of the monthly data collections.

YOUR HELP IS NEEDED !!

We are looking for local stream sites that would benefit from willow plantings.  If you know a spot on one of our local streams that you fish and you think it would benefit from willow plantings contact Don Jiskra (djiskra@comcast.net)
 so that we can add it to the list.  
Sites where stream bank erosion is occuring are of particular interest
.
 Willows are planted either before they develop leaves in the spring or after they drop their leaves in the autumn which constrains these projects to certain limited time frames.  In order to deal with this constraint and handle these planting effectively it is essential that we have an established list of stream sites available to us.  Your efforts in this regard will be appreciated.  Thanks

Guidelines for Cutting and Planting Willow Stakes


As a matter of information the willows in our grove over at the Vassar Farm are basically two varieties, Streamco and Bankers Dwarf.  Bankers is a hybrid, and neither of these varieties are native to Dutchess County.

Cutting:

Select stock during the dormant season in the fall after the leaves have dropped off or in the spring before new leaves emerge.

Select stock that is from three quarters inch to three inches thick. Avoid suckers of current years growth as these lack a sufficient store of energy.   The best wood will be two to five years old.

 

Cut the willow branch off at ground level if possible and closely trim off any side branches.


Cut the branch into fifteen to eighteen inch lengths.  Where soil remains moist throughout the growing season a shorter length can suffice.


Stakes should be healthy, straight wood, and undamaged.

Soak cuttings in water for twenty-four hours and up to two weeks, but keep them in a cool place away from the sun.  Make certain that stakes are in the water butt end down.

When cutting stakes at the Vassar willow grove the unused cut trimmings that are left over should be cleaned up and removed.  Currently we are placing them in a brush pile located in the field to the right and rear of the grove.

Planting:


Use a metal bar and hammer to make pilot holes in the soil.  A pair of loppers should be available to trim the top of the stake if it was damaged by hammering. 


Cut the base, the butt end, of the stake at an angle.


If the soil is soft enough the you may be able to tap the stake into the ground.  Whether you use a pilot hole or hammer the stake, if you mash the top of stake somewhat use a pair of loppers to cut off the damaged top.


Sink stake to seventy-five or eighty percent of its length into the ground.


Be careful not to damage the buds, strip the bark, or split the stake during planting.


Two to five bud scars should be above the ground. Cut off any excessive length.


Stakes should be planted so that the cuttings will not overwhelmed by competing herbaceous vegetation.  They need light.


Stakes should be placed one to three feet apart.  They need not be vertical.  If placed in the side of a stream bank they may actually be more horizontal than vertical.


They should be placed in soil where it is probable that the stake will reach the level of the mid summer water table.  Where this is not possible the stakes will require watering until growth is evident.  As evidenced by the willow grove at the Vassar Farm, with ample watering stakes may be planted without concern for the proximity of a nearby stream.


Be sure to tamp soil firmly around the stake to assure good soil contact.  If hammering the stake into the ground has damaged the top cut off the damaged section. 


Unfavorable soils such as road fill or bare and denuded land will not sustain growth.  While willows may initially show growth they will die after a few years.

Giant Hogweed

Although this plant is currently not known to exist in Dutchess County it has been found in Putnam and Sullivan Counties and the potential to find it in here at some future time is quite good.  It is dangerous to your health so you would be wise to familiarize yourself with this plant.  Click on the link below to learn about it.
