Columbia River Basin Fish Facilities

This dataset includes various facilities used for fisheries management in the Columbia Basin, as well as key hydroelectric dams throughout the Basin. For the purposes of this dataset, a facility is a fixed or semi-fixed location where fish are managed, counted or passed, and generally where there is at least one data record in a Pacific States Marine Fisheries Commission(PSMFC) database. Not all dams fall neatly within this definition, but are included since they are a significant factor in fish distribution. A primary objective of this dataset is to link PSMFC's Columbia Basin fish data programs through a common location framework, while eliminating the redundancy of location data being mapped and managed by the individual program. While the facility location data will be managed by the PSMFC GIS Center as a single dataset, facilities can be separated and published into multiple map layers based on facility type or other attributes. Sources for these point data came primarily from Programs within the Pacific States Marine Fisheries Commission (PSMFC), including StreamNet, PIT Tag Information System(PTAGIS), and the Regional Mark Processing Center(RMPC), and their various state and federal partners. Locations have been checked and in some cases modified, to more closely match available imagery and/or regional hydrography, as appropriate. Inclusion in the dataset or depiction in the mapper does not mean that the facility is currently active. Basic types of fish facilities currently include:• Hatcheries, acclimation / release sites• Dams (categorized further for display purposes)• Fish traps & collection facilities (including screw traps, weir traps, etc.)• Fish passage facilities (including fish ladders and juvenile fish bypasses)• PTAGIS instream remote detection facilities** Note that not all PTAGIS sites are depicted in this dataset.We strive for accuracy and completeness, but expect that improvements to the dataset can be made.

本数据集涵盖哥伦比亚河流域用于渔业管理的各类设施，以及流域内的重点水电大坝。就本数据集的定义而言，设施指用于鱼类管理、计数或过鱼的固定或半固定场所，且通常在太平洋州海洋渔业委员会（Pacific States Marine Fisheries Commission, PSMFC）的数据库中至少存有一条数据记录。并非所有大坝都完全契合这一定义，但鉴于其对鱼类分布具有显著影响，故仍将其纳入本数据集。

本数据集的核心目标之一，是通过统一的位置框架，整合PSMFC的哥伦比亚河流域鱼类数据项目，同时消除各独立项目中位置数据重复映射与管理的冗余问题。尽管设施位置数据将由PSMFC地理信息系统（Geographic Information System, GIS）中心作为单一数据集进行管理，但亦可根据设施类型或其他属性，将设施拆分并发布为多个地图图层。

此类点位数据的主要来源为PSMFC旗下的多个项目，包括StreamNet、PIT标记信息系统（PTAGIS, PIT Tag Information System）以及区域标记处理中心（RMPC, Regional Mark Processing Center），同时整合了其各州与联邦合作方的相关数据。相关点位均经过核查，在适宜情况下还会进行调整，以更贴合现有影像资料及区域水文地理特征。

本数据集收录的设施或地图绘制中的标注，并不代表该设施当前仍处于运行状态。当前涵盖的鱼类设施基础类型包括：
• 孵化场、驯化/放流站点
• 大坝（为便于展示将进一步分类）
• 鱼类诱捕与采集设施（包括螺旋陷阱、堰式陷阱等）
• 过鱼设施（包括鱼道与幼鱼分流设施）
• PTAGIS河道远程检测设施
**请注意，本数据集并未收录全部PTAGIS站点。**

我们致力于提升数据集的准确性与完整性，但仍期待后续可对其进行优化完善。若您有任何更正、补充、建议或疑问，请联系邮箱 [e-mail]
