Eel numbers are going down The population of American eels is declining. What factors could be causing this? Possible Factors Causing Recent Eel Declines Historic order of impact: 1. Habitat loss 2. Dams and barriers 3. Water pollution 4. Overfishing 5. Hydroelectric turbines 6. Climate change 7. Food web changes 8. Parasites (adapted from John Casselman, Queens University) How are people helping to better understand eels? The Hudson River Eel Project 1,000,000+ eels caught & released above barriers since 2008 ~1,000 volunteers annually What is The Glass Eel Project? Fyke nets are set in tributaries of the Hudson. Each day in the spring volunteers and students check the nets, count the eels, record the data, and release the eels above the next barrier to migration.

Assessment of Public Comment on Draft Trout Stream Management Plan
Assessment of public comments on draft New York State Trout Stream Management Plan OCTOBER 27, 2020 Andrew M. Cuomo, Governor | Basil Seggos, Commissioner A draft of the Fisheries Management Plan for Inland Trout Streams in New York State (Plan) was released for public review on May 26, 2020 with the comment period extending through June 25, 2020. Public comment was solicited through a variety of avenues including: • a posting of the statewide public comment period in the Environmental Notice Bulletin (ENB), • a DEC news release distributed statewide, • an announcement distributed to all e-mail addresses provided by participants at the 2017 and 2019 public meetings on trout stream management described on page 11 of the Plan [353 recipients, 181 unique opens (58%)], and • an announcement distributed to all subscribers to the DEC Delivers Freshwater Fishing and Boating Group [138,122 recipients, 34,944 unique opens (26%)]. A total of 489 public comments were received through e-mail or letters (Appendix A, numbered 1-277 and 300-511). 471 of these comments conveyed specific concerns, recommendations or endorsements; the other 18 comments were general statements or pertained to issues outside the scope of the plan. General themes to recurring comments were identified (22 total themes), and responses to these are included below. These themes only embrace recommendations or comments of concern. Comments that represent favorable and supportive views are not included in this assessment. Duplicate comment source numbers associated with a numbered theme reflect comments on subtopics within the general theme. Theme #1 The statewide catch and release (artificial lures only) season proposed to run from October 16 through March 31 poses a risk to the sustainability of wild trout populations and the quality of the fisheries they support that is either wholly unacceptable or of great concern, particularly in some areas of the state; notably Delaware/Catskill waters.

Discovery Report Appendix H Discovery Meeting Summary Memorandum Mid-Hudson Watershed HUC 02020006
Discovery Report Appendix H Discovery Meeting Summary Memorandum Mid-Hudson Watershed HUC 02020006 June 2017 Federal Emergency Management Agency Department of Homeland Security 26 Federal Plaza New York, NY Memorandum To: Mid-Hudson Watershed Discovery Project File From: NYSDEC Floodplain Management Section Date: June 2017 Re: Mid-Hudson Watershed Discovery Meeting Summary Two initial Pre-Discovery webinars were held for all stakeholders within the Mid-Hudson Watershed on May 10, 2016 and May 11, 2016. The purpose of these webinars was to: introduce watershed stakeholders to Risk MAP Discovery project concepts; review the Discovery Stakeholder Survey to be completed by watershed stakeholders; the survey served as a way for FEMA and NYSDEC to collect information upfront on communities mapping needs and existing data that could be incorporated into a possible Risk MAP project; and to discuss upcoming timelines for future Discovery Meetings and the Discovery project overall. Five Risk MAP Discovery Meetings were held in the Mid-Hudson Watershed during the week of October 17, 2016. The purpose of the Discovery Meetings was to present the draft Discovery Report and Maps containing the information collected to date, and to provide the communities with an additional opportunity for input. This memo is a summary of the information collected through the Discovery project engagement process for the Mid-Hudson Watershed and will be used to determine the floodplain mapping restudy priorities.

Lithofacies and Structure of the Taconic Flysch, Melange, and Allochthon, in the New York Capital District
New York State Geological Association 67th Annual meeting & Eastern Section of the American Association of Petroleum Geologists 26th Annual meeting, Union College, Schenectady, NY, October 13-15, 1995 Field Trip A4: October 14th Lithofacies & Structure Of The Taconic Flysch, Melange, & Allochthon In The New York Capital District W.S.F. Kidd, A. Plesch, and F.W. Vollmer This trip will cover the full width of the deformed belt of Medial Ordovician flysch that outcrops adjacent to the Taconic Allochthon. It will include examination of the flatlying flysch bordering the western side of the deformed belt, and of the western part of the Taconic Allochthon, which confines the eastern margin of the deformed flysch belt. Locally, excellent exposures show the structural transition from the undeformed to the folded and thrust flysch, and the further deformation to melange associated with shearing on thrust fault zones. The large-scale domainal structure of the deformed flysch belt, with intercalated belts affected by greater (melange) and lesser (folding) deformation, and by some of the melange containing ‘exotic" clasts, will be illustrated by several stops, including Cohoes Gorge along the Mohawk River. One of the very few exposures of the fault that places the western edge of the Taconic Allochthon against melange will also be visited. The trip aims to demonstrate a structure of the deformed flysch belt of the Hudson Valley dominated by faults, including a significant contribution from out-of-sequence imbrication of older faults, and with most of the flysch and melange being very considerably allochthonous. This picture is similar to that established for the same belt of rocks in southern Quebec, but differs fundamentally from the interpretation shown on recent published geological maps of the Hudson Valley.
