USGS Hydrography Seminar Series

High-quality hydrographic data are critical to a broad range of government and private applications. Resource management, infrastructure planning, environmental monitoring, fisheries management, and disaster mitigation all depend on up-to-date, accurate, and high-quality hydrographic data. The U.S. Geological Survey National Geospatial Program is initiating a new series of virtual seminars to highlight the uses of hydrographic data. These seminars are intended to share success stories from users who have solved real world problems using hydrographic data, provide information about the National Hydrography Dataset and related products, and provide a virtual forum for users, similar to what might be encountered in a conference setting. These seminars will be presented every six to eight weeks and feature applications and speakers from different disciplines.

Connections are limited, and you will need to register to attend these seminars. Please visit to sign up. After your request has been approved, you’ll receive instructions for joining the meeting.

Seminar 7 - Thursday March 17, 2016 - 2:00 PM Eastern - One Hour

Hydrography for Fisheries and Ecosystems
Integrating Hydrography and Fisheries data to assess ecological flows
Dr. Howard Reeves, Research Hydrologist, USGS Michigan-Ohio Water Science Center

Abstract - Information and data from NHDPlus, streamgages and flow-models,stream temperature measures and models, and fisheries surveys were combined to provide science support for the State of Michigan's implementation of the Great Lakes Compact. Products that proved critical to management and policy work included: 1) maps of statewide flows and fish community types; and 2) flow-fish response curves. These same types of data and expanded analysis are being used to assess ecological flows across the US Great Lakes Basin. The analytical and data framework used to build this statewide and regional analysis could be applied across the country.

Biography – Howard Reeves is a research hydrologist in the USGS Michigan-Ohio Water Science Center. Reeves worked on the technical team that supported development of the Michigan Water-Withdrawal Assessment Process and Screening-Tool, and has worked on an interdisciplinary team to move the science used in the Michigan work to the Great Lakes Basin.
