WSDOT - New Zealand Mud Snail Maintenance Areas

This dataset is to inform WSDOT and other state agencies of a known invasive species currently found in Washington State waterways. The New Zealand Mud Snail (NZMS) has been identified in a number of locations throughout the state. If in-water work is necessary within water bodies or connecting tributaries within a two-mile radius of the documented location (latitude and longitude), all personal gear (waders, tools, instruments, etc.) and heavy equipment must be fully decontaminated before being used at any other site. Transport to a secure site for cleaning/decontamination is allowed as long as precautions are taken to avoid any dropping of mud or debris between the work site and the cleaning/decontamination location.This dataset is used as a general reference layer for geographic information systems at the Washington State Department of Transportation (WSDOT). It is maintained by the WSDOT ESO office. Updates to this dataset are on an as needed basis.本数据集用于告知华盛顿州运输局（Washington State Department of Transportation, WSDOT）及其他州级机构，目前在华盛顿州水域中发现的已知入侵物种。新西兰泥螺（New Zealand Mud Snail, NZMS）已在该州多个点位被检出。若在已记录点位（经纬度）两英里半径范围内的水体或连通支流中开展水下作业，则所有个人装备（涉水裤、工具、仪器等）及重型设备在用于其他作业点位前，必须进行彻底去污消毒。只要采取防护措施，避免在作业点位与消毒点位之间洒落泥浆或碎屑，即可将装备转运至合规场地进行清洁消毒。 本数据集作为华盛顿州运输局地理信息系统（Geographic Information Systems）的通用参考图层使用。该数据集由WSDOT ESO办公室负责维护。本数据集将根据实际需求按需更新。
