Coho - Lakes Stratum
The Lakes biogeographic stratum includes Oregon coastal watersheds south of the Siuslaw River and north of the Coos River, excluding the Umpqua River. A small basin (Sutton Creek/Mercer Lake) just north of the Siuslaw River is also included in the stratum. There are a total of 3 independent populations and 1 dependent population in the stratum.
The trend in adult abundance is presented for all strata. Analyses for other criteria are available for the individual populations contained within each stratum.
Progress
At the Stratum level, the only measurable criterion available is spawner abundance.
