Watershed Hydrology

Recommended! Hydrologic Atlas for Ohio On-line, by L. J. Harstine, Ohio Department of Natural Resources, Division of Water. Provides information and maps describing average annual precipitation, temperature, streamflow, and water loss for years 1931-1980.

Recommended! Ohio 14-digit Subwatersheds, by Natural Resources Conservation Service, Ohio office.  View maps of Ohio's 11-digit and 14-digit watersheds with or without stream overlays.

Recommended! Natural Stream Processes, by Ohio DNR Division of Water.  One of the "Ohio Stream Management Guide" series.  Topics covered include: streams as dynamic ecosystems, channel forming and reconditioning processes, channel types and patterns, stream flow dynamics, sediment load in streams, base-flow characteristics of streams, steam ecology and natural purification processes, human impacts on stream processes, stream management objectives, and a watershed approach to stream management.

Recommended! Ohio's Hydrologic Cycle , by Larry Brown. OSU Extension Factsheet (AEX-461-94).  Introduction to the hydrologic cycle, the relationship to water quality, and statistics on water usage in Ohio.

Recommended! On-line Hazard Maps, by Environmental Systems Research Institute, Inc. (ESRI).  Create flood hazard maps for your location.  Shows rough approximation of flood hazard areas based on 50 and 100-year storms.

Recommended! Protecting Instream Flow: How much Water does the river need? This is a module in the U. S. EPA's Watershed Academy 2000.  Developed by B. Richter, The Nature Conservancy's Freshwater Initiative.  Water quantity issues can be as important as water quality issues for restoring biological integrity to a waterway.  This slide show discusses an approach for defining and restoring streamflow conditions in order to sustain biological diversity.

Recommended! Stream Corridor Structure.  This is a module in the U. S. EPA's Watershed Academy 2000 adapted from "Stream Corridor Restoration: Principles, Processes and Practices".  The goal of this module is to introduce users to the features of stream structure as a means to better understanding of how streams and stream corridors function as ecosystems.

Ohio Water Resources by County. OSU Extension Factsheets.  Provides basic information on precipitation, surface-water resources, ground water, usage, and water quality.

Surface Water Information Data, by U. S. Geological Survey.  Data from streamflow monitoring stations is used to create maps and tables indicating streamflow conditions (e.g., dry, normal, wet) for the United States or by state.  Real-time streamflow data is also available if you want to catch up on today's streamflow conditions.
