Classification Of The Alterations Of Beaver Dams To Headwater Streams In Northeastern Connecticut, U.S.A., Denise Burchsted, Melinda D. Daniels

Of the many types of barriers to water flow, beaver dams are among the smallest, typically lasting less than a decade and rarely exceeding 1.5 m in height. They are also among the most frequent and common obstructions in rivers, with a density often exceeding ten dams per km, a frequency of construction within a given network on a time scale of years, and a historic extent covering most of North America. Past quantification of the geomorphologic impact of beaver dams has primarily been limited to local impacts within individual impoundments and is of limited geographic scope. To assess the …

Altered Hydrology In Connecticut Watersheds Prioritized For Protection, Denise Burchsted

The Nature Conservancy (TNC) has selected the Saugatuck, Salmon, Eight Mile, Mount Hope / Natchaug, and Hollenbeck River watersheds for priority protection in Connecticut. A number of threats, including altered hydrology, have been identified in these watersheds. This project has been designed to better understand that threat and provide some context for future protection or restoration of the hydrology within those watersheds. The definition of altered hydrology is problematic, as the time at which the watersheds are considered unaltered is ambiguous and historic data is often unavailable. In order to address that difficulty, this project used the following approach: 1. …
