POD! Fish- DFG North Bay Aqueduct Larval/juvenile fish sampling March-July (1992-2004)

Name of study: North Bay Aqueduct Survey Program element: 096 Program manager: Kevin Fleming, [e-mail] Project Lead: Michael Dege, [e-mail] Agency: Department of Fish and Game, Bay Delta Division Address: 4001 North Wilson Way, Stockton, CA 95205 Phone: [phone], Fax: [phone] Purpose/Objective: This survey has two major foci: 1) Estimate and evaluate larval delta smelt loss at the State Water Project’s North Bay Aqueduct (NBA) due to entrainment and 2) Monitor abundance and distribution of larval delta smelt in the Cache Slough Complex and near Prospect Island. Prospect Island is a CALFED habitat restoration site and this sampling is used to evaluate whether delta smelt would use this site for spawning habitat. Future restoration of Prospect Island will warrant additional monitoring stations. The presence of delta smelt larvae in Barker Slough (Part of the Cache slough complex leading to the NBA) is a criterion for restrictions on NBA pumping. The 1995 Delta Smelt Biological Opinion mandates monitoring at the three Barker Slough stations in Barker Slough and the surrounding areas on a "recent-time" (within 72 hours) basis, posting delta smelt information on the world wide web so that interested parties may use this information for water management decisions. Data collected: Water temperature, surface electro-conductivity, water transparency, water volume sampled, tidal stage, sample time, tow depth, bottom depth, and fish catch. Geographic range of field work: Northern Sacramento-San Joaquin Delta. Number of sites: Eight stations. Period of record (start year): 1995. Size for complete data base for program element in KB (MB): 10+ megabytes. Number of individual files: One file or database contains all data.

项目目标：本项目包含两项核心研究任务：其一，评估并量化州级水资源工程北湾输水道（State Water Project’s North Bay Aqueduct，NBA）因卷吸作用导致的幼体三角洲银汉鱼（delta smelt）损失量；其二，监测卡什斯劳夫综合体（Cache Slough Complex）及普罗斯佩克特岛（Prospect Island）周边水域的幼体三角洲银汉鱼种群丰度与空间分布格局。普罗斯佩克特岛为CALFED栖息地修复项目点，本次采样旨在评估三角洲银汉鱼是否会将该区域作为产卵栖息地。未来针对普罗斯佩克特岛的修复工程将增设额外监测站点。巴克尔斯劳夫（Barker Slough，为卡什斯劳夫综合体中连通北湾输水道的河段）内存在幼体三角洲银汉鱼，是限制北湾输水道抽水作业的法定判定依据。1995年发布的《三角洲银汉鱼生物意见书》（1995 Delta Smelt Biological Opinion）要求以“近期”（72小时内）为频率，在巴克尔斯劳夫及其周边的3个监测站点开展监测，并将三角洲银汉鱼相关信息发布至万维网，以供相关方开展水资源管理决策参考。

采集数据项：水温、表层电导率、水体透明度、采样水量、潮汐阶段、采样时刻、拖网深度、底床水深及渔获物数据。

野外调查地理范围：萨克拉门托-圣华金三角洲北部区域。

监测站点数量：共8个监测站点。

数据记录起始年份：1995年。

本项目单元完整数据库大小：10+兆字节（MB）。

数据存储形式：单个文件或数据库即包含全部采集数据，无分文件存储。
