NOAA ISEMP - Watershed Sciences - Bridge Creek, Oregon Lidar Survey, 2005

These lidar data were collected on September 27, 2005, for the <a href='http://www.nwfsc.noaa.gov/' target='_blank'>NOAA Fisheries Service - Northwest Fisheries Science Center</a> as part of the <a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/index.cfm' target='_blank'>ISEMP</a> (Integrated Status and Effectives Monitoring Program) for the Columbia Basin. Data collection and processing were performed by <a href='http://www.watershedsciences.com/' target='_blank'>Watershed Sciences</a>. The flight covered 122 km² and 26 river kilometers of <a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/projects_bridge_creek.cfm' target='_blank'>Bridge Creek</a>, a tributary to the John Day River in central Oregon. The flight was used as a baseline survey for the Bridge Creek <a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/projects_watersheds.cfm' target='_blank'>Intensively Monitored Watershed</a>, which is nested in the broader <a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/projects_monitoring.cfm' target='_blank'>Status and Trend Monitoring</a> in the John Day Pilot Basin. <br/><br/>Channel incision within Bridge Creek IMW, OR, has degraded instream and floodplain habitat leading to a loss of spawning and rearing habitat, increased summer stream temperatures and reduced base flows impacting steelhead using this system. ISEMP is collaborating with the <a href='http://www.nps.gov/joda/planyourvisit/painted_hills_unit.htm' target='_blank'>National Park Service</a>, NOAA-Fisheries, and the <a href='http://www.blm.gov/or/districts/prineville/index.php' target='_blank'>Bureau of Land Management</a> on a restoration project that will accelerate natural recovery rates of the processes that create and maintain steelhead habitat to substantially increase steelhead productivity within the drainage.

本激光雷达数据集于2005年9月27日收集，旨在为美国国家海洋和大气管理局（NOAA）渔业服务西北渔业科学中心（<a href='http://www.nwfsc.noaa.gov/' target='_blank'>NOAA Fisheries Service - Northwest Fisheries Science Center</a>）的<a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/index.cfm' target='_blank'>综合状况和有效性监测计划（ISEMP）</a>提供支持，该计划针对哥伦比亚盆地的监测。数据收集与处理由<a href='http://www.watershedsciences.com/' target='_blank'>流域科学公司</a>执行。此次飞行覆盖了122平方公里，并对位于俄勒冈州中部的约翰戴河支流<a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/projects_bridge_creek.cfm' target='_blank'>Bridge Creek</a>的26公里河道进行了观测。此次飞行作为Bridge Creek<a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/projects_watersheds.cfm' target='_blank'>密集监测流域</a>的基线调查，该流域是约翰戴河试验流域内更广泛<a href='http://www.nwfsc.noaa.gov/research/divisions/cbd/mathbio/isemp/projects_monitoring.cfm' target='_blank'>状况和趋势监测</a>的一部分。<br/><br/>在俄勒冈州Bridge Creek IMW区域的河道侵蚀导致河流和河漫滩生境退化，进而引发产卵和育幼生境的丧失，夏季河流水温上升以及基流量的减少，这些都对利用该系统的钢头鱼产生了影响。ISEMP正在与<a href='http://www.nps.gov/joda/planyourvisit/painted_hills_unit.htm' target='_blank'>国家公园服务</a>、NOAA-Fisheries以及<a href='http://www.blm.gov/or/districts/prineville/index.php' target='_blank'>土地管理局</a>合作，开展一项旨在加速形成和维护钢头鱼生境的自然恢复速率的项目，以显著提高排水系统内钢头鱼的生产力。
