Topic Fish: Adobe Creek Steelhead Spawning 1987-1998
Caption:  This chart shows the total number of adult steelhead counted by year in Adobe Creek downstream of Manor Lane from 1987 to 1998. Data were collected by the United Anglers of Casa Grande High School. Survey dates varied but generally spanned the entire spawning season from December to March. Some repeat counting may have occurred where surveys were proximal in time. The apparent increase in number of spawners counted may be entirely the result of increased survey effort.
