DAM SUMMARIES

The following 209 summaries of storage in the Northeast Wyoming River Basin are coalesced from the following sources:

Active Dams, State Engineer.s Office Safety of Dams Engineering Div. Database, transmitted by Larry Stockdale, Safety of Dams engineering consultant, 16 Feb. 2001.

Development of an Evaporation Map for the State of Wyoming for Purposes of Estimating Evaporation and Evapotranspiration, Larry Eugene Lewis, University of Wyoming master.s thesis, Department of Civil and Architectural Engineering and the Graduate School, Laramie, Wyoming, May 1978.

Tabulation of Adjudicated Surface Water Rights of the State of Wyoming, Water Division Number Two, Oct. 1999, database transmitted by Rebecca Mathisen, SEO Technical Services Division administrator, 8 Sept. 2000.

The Active Dams database includes a number of codes. The following tables explain them:

Dam Type: Code Dam Type RE Reinforced Earth MV Multi-Arch CN Concrete MS Masonry VA Arch ST Stone TC Timber Crib OT Other ER Rock Fill PG Gravity CB Buttress

Dam Purpose: Code Purpose C Flood Control D Debris Control F Fish and/or Wildlife Habitat H Hydroelectric I Irrigation O Other P Fire protection, Stock, or Small Farm Pond R Recreation S Municipal Water Supply T Tailings

See the section introduction for notes on the Lewis Evaporation Estimates provided for each reservoir.
