Comments:
Per authors, active nest count = # nests detected + 0.5*(juveniles detected). This reservoir considered productive in CO for Western grebe nesting due to 48 active nests in 2 years. The 2 year span between 1998 and 2004 was not named but it is "currently" inactive, assuming that means 2004.
