Jill Hardiman Glen Holmberg Nancy Elder 2015 version 1.0 tabular digital data Reston, VA U.S. Geological Survey http://dx.doi.org/10.5066/F71N7Z6D Aquatic invasive species are often transported between water bodies on boats or boat trailers. Thus, contaminated boats and boat trailers are considered one of the primary vectors for introduction of invasive species into a new water body. This data set was compiled in response to a funding grant from the Bonneville Power Administration Technology Innovation group (Cooperative agreement #59650, Technology Innovation Project #276) to provide a GIS layer of river access points (boat ramps) within the Columbia and Snake Rivers and water bodies throughout the Columbia River Basin. This work builds on an earlier body of work by Wells et al. 2011, Prioritizing Zebra and Quagga Mussel Monitoring in the Columbia River Basin, also funded by the Bonneville Power Administration Technology Innovation group (contract # 00003373), which provided much of the past water quality, use information, and categorical values for the risk of introduction and the risk of establishment (referred to as risk assessment data) of zebra and quagga mussels for a water body. Updated information has been added by collecting additional data on use of water bodies, as well as combined categorical ranking methodology for identifying water bodies that may be high risk for both introduction and establishment of zebra and quagga mussels. This data set contains geographic positioning system (GPS) locational data for boater access points, use data (i.e. recreational, fishing), water quality measurements (e.g. calcium concentrations, pH), risk assessment data, and other physical attributes (i.e. size, elevation) from their associated water bodies where available. Although, some of the recreational use data has been updated since the previous work no new ranking of this data has been done. The intent of this data set is to provide an online, spatial database for states and regional managers to reference. The GPS locational data was compiled from various resources (including state, federal, tribal, local governing bodies, etc.) to identify boater access points along the mainstem Columbia and Snake Rivers and throughout the Columbia River Basin. Water body data attributes were also compiled from a variety of resources including state, federal, provincial and local governing agencies, as well as Tribes, universities, and public utilities, from which direct data calls were sent for information on monitoring activities, water quality data, and recreational use information. In addition to these agencies a variety of websites were used to download reports and individual data items for water bodies across many different states. A list of websites accessed throughout the data compilation process is included in the data source inputs section. This is the tabular data used to create the boatramps shapefile. The threat of aquatic invasive species (AIS), in particular zebra and quagga mussels being introduced, established, and spreading throughout the Columbia River Basin is a major concern to management and potential impacts to the Federal Columbia River Power System (FCRPS). The presence and colonization of AIS could potentially reduce efficiency and require significant and costly mitigation efforts to the FCRPS. Thus, the development of programs and tools to prevent new introductions and control the spread of AIS are needed. This information was intended to contribute to an initial prioritization of the placement of boat cleaning stations and also to identify additional information that may be needed for a more comprehensive prioritization process. The data set is for planning purposes and to aid in the prevention of the spread of aquatic invasive species, in particular invasive zebra and quagga mussels (Dreissenids) throughout the Columbia River Basin. Data was compiled from a variety of sources for this project. Not all data items were able to be cross-checked or validated for accuracy. They are presented in good faith that proper quality assurance and quality control procedures were performed prior to data being released by the collecting agency, reporting agency, or published on an organization's website. This data set may not represent all the available data pertinent to each boat ramp, but instead represents the data that was provided by the various agencies. As a result, there are many missing values across column attributes where data was reported by only one state or agency, and is not reported by others. Furthermore some attributes were collected opportunistically based on agency resources for particular water bodies and were not explored for all. Some boat ramp locations may not have any additional attribute data discovered for this data set. Another important distinction is that most of the attribute data was collected at the scale of the water body and not at the scale of the boat ramp. An individual water body often has numerous boat ramps and thus each access point within that water body will have the same attribute data. In the case of larger water bodies such as the mainstem Columbia and Snake Rivers, attribute information is typically provided at the reservoir scale or at the closest geographic location in which risk assessment data was collected to the boat ramp. Data updates were last referenced March 2013 and have not been updated since then and there is no current plan to update this data set. 20150301 Data was gathered over multiple years and from multiple sources and is considered up to date to March, 2015.

Cook WA 98605 509-538-2299 509-538-2843 jhardiman@usgs.gov This project was funded by the Bonneville Power Administration Technology Innovation group (contract number 59650) and in collaboration with Washington State University - Vancouver campus partners: Stephen Bollens and Gretchen Rollwagen-Bollens. This work also builds on an earlier effort by Portland State University Center for Lakes and Reservoirs, corresponding author Steve Wells. Glen Holmberg and Nancy Elder of the U.S. Geological Survey, Western Fisheries Research Center compiled a large portion of the data presented here. Tim Counihan also with the U.S. Geological Survey, Western Fisheries Research Center, was the project manager for this effort. Environment as of Metadata Creation: Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.1 (Build 3143) Service Pack 1 (Build 10.1.1.3143) No formal attribute accuracy tests were conducted. Data checks were performed to ensure that boat ramp locations were merged with the correct water body and water name associated with it's gps location. GPS locational information were checked for correct format and expected ranges. Data quality checks were performed throughout the process of merging new data to existing boat ramp data to ensure proper alignment with water bodies and data integrity. Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details about the data set and individual attribute data. Data is limited to boat access points within the Columbia River Basin, in particular emphasis is placed on boater access points, primarily being the presence of a boat ramp. Thus, this data set does not include all water body access points. Missing data values are common throughout this data set as a result of no data being available for a particular attribute (i.e. information is not collected by any particular agency), data was not discovered or reported, or data simply does not exist. Data was collected as time and resources allowed for this project. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable.

Boater access points (gps locational data for boat ramps) were compiled through direct data calls to various agencies throughout the Columbia River Basin and through web searches and from past efforts by Wells et al. 2011. This data set consisted of a gps point, boat ramp location description, and water body name. Each boat ramp access point was assigned a standardized water body name and unique ID in order to merge associated risk assessment information with that water body from the various disparate sources. A standardization of water body names was developed by USGS personnel in order to maintain consistency of water body names as reported by different agencies. Also a unique ID had to be established due to the fact that many water bodies have the same name within and across states. Data associated with potential risk assessment for aquatic invasive species were also assigned a water body name and unique ID. The data sets were merged using SAS (SAS 9.3, © 2002-2010 SAS Institute Inc.) by the unique ID and water body name. Data checks were perfomed each time a merge process was performed to ensure water body and risk assessment data were being properly matched. We did not obtain use or water quality information at the scale of the boat ramp, thus information associated with a boat ramp is at the water body scale, other than the location description. If a boat ramp location does not have any associated risk assessment attribute information these will have a “.” indicating missing values. The merged risk assessment data includes a reference locational gps point (Lat_ra and Long_ra) for the associated risk assessment attribute information. These are not necessarily the point of actual data collection (i.e. water quality measurements), but provide a reference for the water body location for mapping purposes. Attribute data associated with each water body was acquired from many different sources (see data source list), including direct from agencies (published and nonpublished data), publications, and web searches. These typically varied by state as to what recreation and use information was collected and reported, and results in many missing data values across the individual attributes for the entire data set (i.e. states that do not collect the same information). Additional water quality data (calcium concentration measurements and pH) and risk of introduction and risk of establishment categories were obtained from the Wells et al. 2011 publication as well as some past recreational use data for the individual states. Since many different data sources were used to compile the risk assessment attribute data, at times individual attribute data may have multiple values from different sources. In these cases the values that would indicate the highest potential for risk of establishment or introduction were reported, as in a “worst case scenario”. Data originators have documented to the best of their ability all of the disparate data sources used to compile the attribute information in the data sources list. 20150918 Entity point 1603 Boatramps_091815 GPS points for boat access locations, imported as an x, y data set using the lat and long fields for boat ramp locations GPS coordinates (latitude and longitude) were compiled from a variety of sources, including state agencies and British Columbia provincial agencies Water_Name A naming convention for the larger water body containing or connected (as a source) to the water body for which the data is for. The data source includes agencies in which data was collected, as well as USGS personnel, and a variety websites sources (geonames.usgs.gov, google maps) as listed in the overall data set description. Water_Body Standardized naming convention for the water body in which the data is associated with to be used to merge to other data using the common water body name and a unique ID incorporating the name. Water body names came from agencies collecting information and USGS personnel standardizing across the agencies. County Name of the county in which the water body is within. An individual water body can cross more than one county, so multiple counties may be listed. Additionally, in order to adhere to a unique ID a county name may be different than the associated GPS location if a water body crosses multiple counties and/or states. County names were supplied by agencies collecting the data, or added to water body locations using a spatial merge process within ArcGIS using census data from 2010 for the county spatial layer (http://www.census.gov/geo/www/tiger). Countycode A four letter code derived from the first four letters from the county associated with the water body. Some county codes may differ than the county which the GPS point may fall within if the water body crosses more than one county. Naming convention of the first four letters from the county column or the standardized county code applied to that water body. ST_Provinc A two letter abbreviation for the state or province (BC=British Columbia) in which the water body falls within. At times a waterbody will cross more than one state and will have two listed or just one for naming convention purposes. Data source was from collecting agencies or USGS personnel. Location Description of boat ramp location where available. Various sources from state, federal, provincial and local governing agencies. ID A unique identifier code created for the water body. Unique ID was typically made up of the Water body_First four letters of the county name_state abbreviation. This was modified for water bodies that covered multiple states and counties to a simpler format, which may not include the county code and state abbreviation.
