Anglers Symposium on November 9th

Posted on: October 30th, 2018 by Brent Gotsch

Ron-Nev Anglers Symposium 2018

Our friends and col­leagues with the Rondout-Neversink Stream Man­age­ment Pro­gram will be hold­ing their 5th Annual Angler’s Sym­po­sium at the Claryville Event Cen­ter at the Blue Hill Lodge located at 1471 Den­ning Road on Fri­day, Novem­ber 9th from 1:00–4:00pm. This is a great pro­gram for any­one who is inter­ested in the Catskill region fishery.

Head­lin­ing this year’s sym­po­sium will be his­to­rian Diane Galusha who will speak about Edwin Hewitt, an author and nat­u­ral­ist whose prop­erty along the Nev­ersink River inspired him to write his Hand­book of Stream Improve­ment and Secrets of Salmon.

Also pre­sent­ing will be Shaun McAdams from Trout Unlim­ited who will describe his work with wild brook trout in New York and Penn­syl­va­nia. In addi­tion, Carri Marschner and Char­lotte Malm­borg of Cor­nell Uni­ver­sity will speak about cit­i­zen sci­ence oppor­tu­ni­ties to help save hem­lock trees. Hem­locks are vitally impor­tant ripar­ian tree species that are under threat from cli­mate change and inva­sive species like the hem­lock woolly adel­gid. There will also be a walk­ing tour of a nearby stream­bank restora­tion project.

Spotted Lanternfly Discovered in New York State

Recently, the New York State Depart­ment of Envi­ron­men­tal Con­ser­va­tion (NYSDEC) and the NYS Depart­ment of Agri­cul­ture and Mar­kets (NYSDAM) announced that Spot­ted Lantern­fly (Lycorma del­i­cat­ula) was dis­cov­ered in Albany and Yates coun­ties. So far only two sin­gle adult insects have been dis­cov­ered but the con­cern is that there could be more. First dis­cov­ered in Penn­syl­va­nia in 2014 Spot­ted Lantern­fly (SLF) has since been found in New Jer­sey, Delaware, Vir­ginia, and now New York.

SLF is an inva­sive species that is native to Asia, specif­i­cally parts of China, India, and Viet­nam. With no native preda­tors to keep its pop­u­la­tion in check, there is con­cern that SLF could have a sig­nif­i­cant impact on our native forests. Although their pri­mary source of food is the Tree of Heaven (Alianthus altissima), an inva­sive species itself which con­trary to pop­u­lar belief grows in more than just Brook­lyn, it has been known to feed on a wide vari­ety of plants includ­ing grapevine, hops, wal­nut and sev­eral types of fruit trees. This has the poten­tial to impact sev­eral multi-billion dol­lar indus­tries includ­ing grape and hop pro­duc­tion, the fruit grow­ers and log­ging. Sev­eral ripar­ian species are also at risk includ­ing maples, oaks, pines, poplars, sycamores, and wil­lows. This, cou­pled with the die-off of hem­locks and ash trees caused by Hem­lock Wooly Adel­gid and Emer­ald Ash Borer, respec­tively, could have severe con­se­quences for ripar­ian cor­ri­dor ecosys­tem health and stability.

SLF lay their eggs between the months of Sep­tem­ber and Decem­ber. Newly laid egg masses have a grey mud-like cov­er­ing that can take on a dry cracked appear­ance over time. Old egg masses appear as rows of 30–50 brown­ish seed-like deposits in 4–7 columns on the trunk that are roughly an inch long. Eggs hatch between the months of May and June. SLF nymphs emerge and are black with bright white spots. At this stage they are roughly the size of a pen­cil eraser. Over the next sev­eral months they grow larger but main­tain their col­ors until between the months of July and Sep­tem­ber where they turn bright red with dis­tinct patches of black and bright white spots. From July through Decem­ber SLF matures into an adult that has wings that are about 1-inch-long that are grey with black spots. When the wings are opened it reveals a red underwing.

SLF feeds by using it mouth­parts to pierce and then suck the sap from the trunks, branches, twigs and leaves. This cre­ates a weep­ing wound of sap. As it digests the sap, SLF secretes a sub­stance known as hon­ey­dew. This com­bined with the flow­ing sap tends to col­lect at the base of the trunk and pro­vides a fer­tile area for the growth of fungi and mold that may stunt plant growth or even cause pre­ma­ture death. It may also attract bees, wasps, ants and other insects to the site, fur­ther stress­ing the plant.

If you think you have SLF on your prop­erty please take a pho­to­graph of either the nymph, adult insect, egg mass, or infes­ta­tion sign along with an item for scale (such as coin or ruler) and email them to Be sure to note the loca­tion includ­ing address, inter­sect­ing road, land­marks or GPS coor­di­nates. Also report the infes­ta­tion to iMap­In­va­sives.

For more infor­ma­tion on SLF be sure to visit the NYSDEC Web­site on SLF as well as web­sites devoted to SLF on the Penn­syl­va­nia Depart­ment of Agri­cul­ture and Penn State Exten­sion websites.

AWSMP at Olive Day 2018

Posted on: September 4th, 2018 by Brent Gotsch

AWSMP will be attend­ing this year’s Olive Day on Sep­tem­ber 8 from 9:00 am to 5:00 pm at the Lester Daivs Park located at 686 Wat­son Hol­low Road in West Shokan, NY (right next door to the Olive Town Hall). Olive Day is an annual event that cel­e­brates all the things that make the Town of Olive a spe­cial place to live. There will be food, live music, a vari­ety of ven­dors, local and regional orga­ni­za­tions with edu­ca­tional dis­plays, and activ­i­ties for chil­dren and fam­i­lies includ­ing the always pop­u­lar frog race!

AWSMP will have a table with pro­gram lit­er­a­ture as well as an edu­ca­tional dis­play. We will also be bring­ing our stream table. The stream table shows how water inter­acts with and shapes the land­scape around it. It also shows how human inter­ven­tion in streams can change how water flows and the shape and depth of the stream.

Stop on by to see the stream table in action, pick up some lit­er­a­ture and say hi. We look for­ward to see­ing you at this year’s Olive Day!

AWSMP Youth Educator Matt Savatgy uses the stream table to show youth how manipulation of the stream channel can cause changes in the surrounding landscape during Olive Day 2017.

Riparian Buffer Grand Opening!

Posted on: August 27th, 2018 by Leslie_Zucker

Join the Catskill Cen­ter and the AWSMP at the Mau­rice D. Hinchey Catskill Inter­pre­tive Cen­ter (CIC) on Thurs­day, August 30 from 12pm — 1pm for the Grand Open­ing of a ripar­ian buffer! The buffer is located along a small forested stream at the back of the CIC park­ing lot. Meet for a rib­bon cut­ting at the trail bridge where the buffer is located. Streams ben­e­fit in mul­ti­ple ways from hav­ing native veg­e­ta­tion on their bor­ders. This buffer fea­tures Catskill native species and inter­preted sig­nage that iden­ti­fies the plants and explains the impor­tance of stream­side veg­e­ta­tion. The buffer was installed with the help of vol­un­teers who worked hard to clear inva­sive plants from the site. The buffer will con­tinue to be main­tained by vol­un­teers, who are gath­er­ing before the grand open­ing from 9am — 12pm for another Inva­sive Plant Pull! Bring your fam­ily and friends to learn more about how you can main­tain clean, cool Catskills water on your property.

Staff from the Ulster County Soil and Water Con­ser­va­tion Dis­trict (SWCD) will be on hand to answer your ques­tions. The native plant buffer was planned and installed by the Catskill Streams Buffer Ini­tia­tive, a pro­gram of the Ulster SWCD and NYC Depart­ment of Envi­ron­men­tal Protection.


Bankfull Flows on Friday

Posted on: August 20th, 2018 by Tim Koch

On the evening of Fri­day, August 17th, 2018 some­thing very impor­tant hap­pened in the world of stream sci­ence and man­age­ment. The Eso­pus Creek, Birch Creek, and Wood­land Creek reached “bank­full discharge”.

Bank­full dis­charge is the amount of water flow­ing in the stream when the chan­nel is com­pletely filled to the brim, mea­sured in cubic feet per sec­ond (cfs). At bank­full, all the water is still con­tained within the chan­nel. Once bank­full has been exceeded, water spills out onto the flood­plain and the stream is tech­ni­cally flood­ing. The pho­to­graph below shows the Stony Clove Creek at near bank­full flow. The  unde­vel­oped flood­plain vis­i­ble on the left is acces­si­ble to the stream and ready to accept any flood waters in excess of bankfull.

(a) Stream cross sec­tion show­ing bank­full stage, (b). the head­wa­ters of Stony Clove Creek flow­ing at ~800 cfs, approach­ing bankfull

In the humid north­east, most streams will see a bank­full flow event every 1.5 years on aver­age. The last time we saw a bank­full flow in the Ashokan water­shed was Octo­ber 2017.

If any flow over bank­full means that the stream is flood­ing, then we can expect our rivers and streams to flood at least once every year and half. This is nat­ural, sta­ble stream behav­ior and high­lights the impor­tance of flood­plain management.

Bank­full dis­charge is crit­i­cal to stream man­agers because over time it is the flow that moves the largest amount of sed­i­ment, effec­tively shap­ing and main­tain­ing the chan­nel form. Due to the impor­tance of bank­full dis­charge for chan­nel main­te­nance, some of the research projects that we fund at AWSMP have trig­gers that are acti­vated fol­low­ing bank­full flow events.

Below is a chart that com­pares the stream flows observed on Fri­day the 17th (far right) to bank­full dis­charge. The Q1.5 col­umn is an esti­mated bank­full dis­charge based on sta­tis­tics. This is a use­ful esti­mate for bank­full when field derived val­ues are not avail­able. The most accu­rate way to deter­mine bank­full dis­charge is to read the stream. A well-trained eye can locate bank­full indi­ca­tors in the field such as depo­si­tional fea­tures or changes in bank slope, veg­e­ta­tion, and par­ti­cle size. By using these indi­ca­tors as a guide to mea­sure the dimen­sions of the stream chan­nel, highly accu­rate bank­full dis­charge val­ues can be cal­cu­lated (mid­dle column).

Woodland Creek Stream Restoration Update

Posted on: August 20th, 2018 by Leslie_Zucker

The Wood­land Creek stream restora­tion project is under­way! A sec­tion of Wood­land Creek just upstream of the Wilmot Way bridge is being restored to sta­ble con­di­tions to pre­vent fur­ther bank ero­sion and down­cut­ting of the stream chan­nel. Ero­sion has exposed heavy clay deposits that turn the stream a muddy brown after it rains. Con­struc­tion con­trac­tor Kingston Equip­ment Rental/Baker Broth­ers Exca­vat­ing and the Ulster County Soil & Water Con­ser­va­tion Dis­trict work­ing with project engi­neer Milone & MacB­room are imple­ment­ing the project. See pho­tos of the ini­tial phases of con­struc­tion below.

New Student Video on Importance of Streams

Posted on: August 13th, 2018 by Leslie_Zucker

The Water­shed Detec­tives Club at the Ben­nett Ele­men­tary School have pro­duced a new video titled “The Impor­tance of Streams” with assis­tance from the AWSMP. The 30-minute sci­ence edu­ca­tion video is now online for all to see! Water­shed Detec­tives Club is an after-school sci­ence club where stu­dents learn about streams and the Ashokan Reser­voir water­shed, part of the NYC Drink­ing Water Sup­ply Sys­tem. Stu­dents made the video after a year study­ing local streams, water qual­ity, and water conservation.

This moti­vated group of fourth, fifth and sixth-grade stu­dents were involved in all aspects of the movie-making process. They worked as actors, direc­tors, cam­era, light and sound tech­ni­cians, cue card hold­ers and even caterers.

Stu­dents pro­duced the video over a three-month period with the assis­tance of their club advi­sor, Matt Savatgy, a youth edu­ca­tor with Cor­nell Coop­er­a­tive Exten­sion of Ulster County (CCEUC), and retired Onte­ora teacher and video­g­ra­pher David Laks. The video was made pos­si­ble with edu­ca­tion fund­ing pro­vided by the New York City Depart­ment of Envi­ron­men­tal Protection.

The video serves as a use­ful tool for ele­men­tary school teach­ers or any­one eager to learn more about their local water resources. Edu­ca­tional insti­tu­tions can con­tact the AWSMP office for a free DVD copy at (845) 688‑3047.
