June 2016 VersionData Content:This data set contains all CalWater 2.2.1 Planning Watersheds (PWS) where CDFW has documented coho salmon to be present during or after 1990. It was developed for the express purpose of assisting with Coho salmon recovery planning efforts. NOTE: Acreages are calculated for area inside California only. It is important to note that this data set does not attempt to model the entire possible distribution of the species. Rather, it only represents planning watersheds intersecting the known distribution, which is based on where the species has been observed and reported. While the distribution data may indeed represent the extent of the species, generally the upstream extent of the distribution only represents the location of positive sampling or other observations.. Therefore, this data set likely represents an underestimation of the absolute geographic distribution of the species. Data Source:This watershed level data set was derived by intersecting Calwater PWS with point and line features depicting Coho salmon distribution. These features are derived from a subset of data contained in thedevelopers file geodatabase (©Environmental Science Research Institute (ESRI) 2016). This is an ongoing project developed by CDFW Northern Region Data Management and GIS with assistance from CDFW Biogeographic Data Division and Pacific States Marine Fisheries Commission. These data are based upon confirmed observations of Coho salmon. Effort has been made to identify and correct watersheds that were erroneously selected due to inaccuracies from using data of different scales. The observation data that are the basis for the distribution were compiled from a variety of disparate sources including but not limited to CDFW, U.S. Forest Service, National Marine Fisheries Service, timber companies, and the public. Forms of documentation include CDFG administrative reports, personal communications with biologists, observation reports, and literature reviews.This derived dataset is meant to be continually updated as additional information is acquired. As such, any copy of this dataset is considered to be a snapshot of the known Coho Distribution at the time of release. It is incumbent upon the user to ensure that they have the most recent version prior to making management or planning decisions.Data Usage: Examples of appropriate uses include: Coho salmon recovery planning Evaluation of future survey sites for Coho Validating Coho distribution models Examples of inappropriate uses include: Using this data to make parcel or ground level land use management decisions. Using this data set to prove or support non-existence of coho at any spatial scale. Assuming that Coho are prevalent throughout the entire watershed. All users of this data should seek the assistance of qualified professionals such as surveyors, hydrologists, or fishery biologists as needed to ensure that such users possess complete, precise, and up to date information on Coho salmon distribution and water body location. Please refer to "Use Constraints" section below.

June 2016 VersionThis dataset represents the "Observed Distribution" for coho salmon in California by using observations made only between 1990 and the present. It was developed for the express purpose of assisting with species recovery planning efforts. The process for developing this dataset was to collect as many observations of the species as possible and derive the stream-based geographic distribution for the species based solely on these positive observations.For the purpose of this dataset an observation is defined as a report of a sighting or other evidence of the presence of the species at a given place and time. As such, observations are modeled by year observed as point locations in the GIS. All such observations were collected with information regarding who reported the observation, their agency/organization/affiliation, the date that they observed the species, who compiled the information, etc. This information is maintained in the developers file geodatabase (©Environmental Science Research Institute (ESRI) 2016).To develop this distribution dataset, the species observations were applied to California Streams, a CDFW derivative of USGS National Hydrography Dataset (NHD) High Resolution hydrography. For each observation, a path was traced down the hydrography from the point of observation to the ocean, thereby deriving the shortest migration route from the point of observation to the sea. By appending all of these migration paths together, the "Observed Distribution" for the species is developed.It is important to note that this layer does not attempt to model the entire possible distribution of the species. Rather, it only represents the known distribution based on where the species has been observed and reported. While some observations indeed represent the upstream extent of the species (e.g., an observation made at a hard barrier), the majority of observations only indicate where the species was sampled for or otherwise observed. Because of this, this dataset likely underestimates the absolute geographic distribution of the species.It is also important to note that the species may not be found on an annual basis in all indicated reaches due to natural variations in run size, water conditions, and other environmental factors. As such, the information in this dataset should not be used to verify that the species are currently present in a given stream. Conversely, the absence of distribution linework for a given stream does not necessarily indicate that the species does not occur in that stream. The observation data were compiled from a variety of disparate sources including but not limited to CDFW, USFS, NMFS, timber companies, and the public. Forms of documentation include CDFW administrative reports, personal communications with biologists, observation reports, and literature reviews. The source of each feature (to the best available knowledge) is included in the data attributes for the observations in the geodatabase, but not for the resulting linework. The spatial data has been referenced to California Streams, a CDFW derivative of USGS National Hydrography Dataset (NHD) High Resolution hydrography.Usage of this dataset:Examples of appropriate uses include:- species recovery planning- Evaluation of future survey sites for the species- Validating species distribution modelsExamples of inappropriate uses include:- Assuming absence of a line feature means that the species are not present in that stream.- Using this data to make parcel or ground level land use management decisions.- Using this dataset to prove or support non-existence of the species at any spatial scale.- Assuming that the line feature represents the maximum possible extent of species distribution.All users of this data should seek the assistance of qualified professionals such as surveyors, hydrologists, or fishery biologists as needed to ensure that such users possess complete, precise, and up to date information on species distribution and

The Coho Tasks Database contains the Implementation Tasks from tables 9.1, 9.2, and 9.3 of the Recovery Strategy for California Coho Salmon (2004). The data was normalized and cross-referenced to Calwater 2.2.1 watershed units. Some updates were performed in 2005 and are noted in the data. The database contains a set of related tables primarily related to the TASK table. The TASK table includes a description of the activity to perform. The PRIORITY table contains the description of the coded TASK.PRIORITY column. Similarly, the LEVEL table contains the description for the coded TASK.LEVEL column. The TASK_FOOTNOTE table is a many-to-many bridge between the TASK and FOOTNOTE tables. This captures the footnotes for tasks from the original document. Finally, the TASK_CALW contains the mapping of TASK records to Calwater 2.2.1 records. A task may be mapped to zero or more TASK_CALW records. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000714.

Juvenile coho salmon seek slow velocity areas as rivers rise during storm events. Studies have shown significant increase in juvenile coho salmon growth and survival when they have access to slow water refuge in off-channel ponds during these storms. In addition, off channel features also provide habitat for several other animals including reptiles, amphibians and numerous bird species. In 2014, Humboldt Redwood Company (HRC) identified an abandoned overflow channel that had the potential to become off channel habitat in Lawrence Creek located within the Van Duzen River watershed and asked the National Marine Fisheries Service (NMFS) to partner on the project. NMFS conducted the physical surveys, created the design, and a small competitive internal grant from NOAA provided funding for part of the project construction. HRC worked on the permits, donated heavy equipment and operators as well as several large logs with root wads to build the instream structures.

In-stream habitat data include measurements of a variety of physical and aquatic stream attributes that collectively reveal a great deal about stream condition for salmonids and trout. Characterizing and inventorying the physical conditions that define stream habitat for salmonids is an important part of the habitat restoration process. The California Department of Fish and Wildlife (CDFW) collects data on a number of physical attributes of streams and classifies these streams by one of several habitat types. The in-stream habitat data collection process involves two distinct steps; identifying channel type and assigning a habitat type. These in-stream habitat data are used for a variety of purposes including analysis of stream suitability for supporting salmonid populations, as part of larger and more complex watershed assessments, and to establish baseline conditions against which future assessments can measure change. They are a critical part of determining restoration priorities and identifying salmonid refugia. The California Salmonid Stream Habitat Restoration Manual published by the CDFW, describes the process of using in-stream habitat data and other data and information for identifying streams with restoration potential and working through the stream restoration process.The objective of stream inventory reports are to document the current habitat conditions and recommend options for the potential enhancement of salmonid habitat. Recommendations for habitat improvement activities are based upon target habitat values suitable for salmonids in Californias streams.

Critical habitat includes the stream channels within the designated stream reaches, and includes a lateral extent as defined by the ordinary high-water line (33 CFR 319.11). In areas where ordinary high-water line has not been defined, the lateral extent is defined by the bankfull elevation. Bankfull elevation is the level at which water begins to leave the channel and move into the floodplain and is reached at a discharge which generally has a recurrence interval of 1 to 2 years on the annual flood series. Critical habitat in lake areas is defined by the perimeter of the water body as displayed on standard 1:24,000 scale topographic maps or the elevation of ordinary high water, whichever is greater.See the final rule (73 FR 7816) for descriptions of areas excluded from this critical habitat designation. Excluded Indian lands were not clipped out of the data.

This dataset was created using the 123 PISCES extant species range layers listed below in the table. The PISCES datasets were converted to rasters using GIS and then map algebra was used to calculate the total number of species in each huc12 watershed. Using GIS, an extended table was created to provide species lists by watershed using a one to many table relate. Species presence data was provided by PISCES: Moyle, Quinones and Bell (direct addition), Moyle and Randall (gstpoly), . These layers were generated by PISCES on 10/30/2014.
