Spawning Ground Survey Database (SGS)

Independent

The Spawning Ground Survey database (SGS) was designed as a repository for raw, unexpanded data collected during spawning ground surveys and from adult traps. It is intended to provide a common framework for the collection, storage, retrieval, and dissemination of data collected by public and private entities. WDFW maintains a centralized copy of the database, which contains historic and current spawning ground survey data from throughout Washington.

The overall objective of SGS is to help monitor status and trends of Coastal, Puget Sound, and Columbia Basin salmonid stocks. SGS is built from a series of seasonal, systematic surveys of both index and “random” stream sections for evidence of adult salmonid spawning activity. Counts of adult fish and redds (nests) are recorded, which provide some of the raw material for generating spawning escapement estimates by species and stock. Escapement estimates are a major component of our assessment of the status (health) of each stock. Questions associated with run timing and distribution of stocks may be answered by analyzing the temporal and spatial data in SGS. These estimates can be found in the Salmonid Stock Inventory (SaSI).

To request SGS data, please use the form on the web page. You can use the menus to specify the watersheds (WRIA), list of species and time-span of data needed, or alternately, include a detailed request to the data manager. To limit the amount of data you receive to a manageable size, it is helpful to be as specific as possible in your request. Data can be obtained for specific streams or rivers rather than entire watersheds.

Centralization of SGS data is an ongoing effort. As such, the SGS database is not all-inclusive and may not contain all SGS data that has been compiled for an area of interest. If data appears to be missing please contact the nearest WDFW regional Fish Program office for assistance, or the Fish District Biologists.
