New England Rivers Fish Assemblage Study Completed

Author: Chris Yoder

MBI with support from U.S. EPA conducted an assessment of the fish assemblages in the rivers of New England during 2002-9. This included a survey of Maine Rivers in 2002-7 and the development of a fish Index of Biotic Integrity (IBI). Two project reports were recently posted on the MBI publications pages and include Development of Methods and Designs for the Assessment of the Fish Assemblages of Non-Wadeable Rivers in New England (Final Report and Appendices) and Maine Rivers Fish Assemblage Assessment: Development of an Index of Biotic Integrity for Non-wadeable Rivers. (Addendum December 31, 2015). The New England report includes an assessment of the status of more than 370 sites in 36 individual rivers, an analysis of the most limiting stressors to the fish assemblage, and case studies of specific impacts observed in the Connecticut River. The report is complete with appendices including a fish distribution atlas for New England rivers. The development of the Maine IBI was originally published in 2008 and this version is an update that includes the diadromous IBI metrics. Data collection continues today in the lower Kennebec and Sebasticook Rivers to develop a long term database and to assess the effectiveness of diadromous fish restoration efforts. We encourage feedback about these reports with any questions or inquires being directed to Chris Yoder, Research Director.

USGS StreamStats

Author: Rachel Day

Water quality and chemical assessments are just some of the many services MBI offers. Such evaluations reveal the impacts (or absence) of local stressors near the sampling sites in a river or stream as well as potential sources of ecological impairment further upstream in the watershed. A critical aspect of conducting these water quality surveys is to determine the drainage area for each sampling site.

Delineating a watershed may be accomplished through a variety of methods. For example, ESRI's Arc Hydro data model and toolset as well as the National Hydrography Dataset (NHD) Plus are beneficial resources for calculating drainage areas. One of the quickest, and easiest, applications is available online at the U.S. Geological Survey's (USGS) StreamStats website (http://water.usgs.gov/osw/streamstats/). This interactive map allows users to enter predefined coordinates or simply use the cursor to select the desired watershed to delineate. In addition to viewing the watershed boundary, users are also able to download the shapefile and view a variety of flow and basin characteristics (examples shown below).

MBI applies the watershed data obtained from USGS StreamStats (or a comparable application) towards many projects throughout the Midwest. Such information aids in the preparation of a complete analysis for water quality and chemical assessments.

2016 Vernal Pool Workshops and Follow Up Expedition

The 2016 Vernal Pool Workshops were a success and we had great attendance.

We're looking forward to the Follow-Up Expedition on May 14th to see what is going on in the pools during the later spring months. There is no charge, but please be sure to register here to help us organize and communicate with participants.

The details are as follows:

Vernal Pools Follow-Up Expedition

Meet at 10 AM at Gahanna Woods State Nature Preserve, located in Franklin County on Taylor Station Road just east of Gahanna.

We look forward to seeing you there!
