NOTATION
Throughout this document, a combination of English and metric measurements are used
according to their predominate usage for specific data categories. English equivalents are
used to identify distances along the Colorado and Gunnison rivers (miles) and for
measurements related to river flow (cubic feet per second [cfs]) or water volume (acre-feet
[af]). English measurements for these parameters were used in this document because of their
common usage. For example, river flows are reported by. the U. S. Geological Survey (USGS)
in cfs, and reporting flow recommendations in metric units would require reconversion to cfs
before they would be meaningful to many readers (e.g., dam operators and water users).
Metric units are most commonly used for biological work associated with the native fishes,
and they were retained for that purpose in this report.
