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.

研究目标：本调查包含两大核心方向：1）评估并核算州级水资源工程北湾输水管道（North Bay Aqueduct, NBA）因夹带作用导致的幼体三角洲胡瓜鱼（delta smelt）损失量；2）监测卡什泻湖群（Cache Slough Complex）及普罗斯佩克特岛（Prospect Island）周边幼体三角洲胡瓜鱼的丰度与分布。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胡瓜鱼是否会将该区域作为产卵栖息地。未来对普罗斯佩克特岛的修复工程将需要增设更多监测站点。
巴克泻湖（Barker Slough，隶属于卡什泻湖群且连通北湾输水管道）内存在三角洲胡瓜鱼幼体，是限制北湾输水管道抽水作业的判定标准之一。1995年发布的《三角洲胡瓜鱼生物意见书》要求以“近期”（72小时内）为监测频次，在巴克泻湖及周边区域的3个巴克泻湖监测站开展监测，并将三角洲胡瓜鱼相关信息发布至万维网，以供相关方参考制定水资源管理决策。

采集数据指标包括：水温、表层电导率、水体透明度、采样水体体积、潮汐阶段、采样时间、拖网深度、底床深度以及渔获物信息。

野外作业地理范围：萨克拉门托-圣华金三角洲北部区域。
监测站点总数：共8个监测站。
数据记录起始年份：1995年。
项目单元完整数据库规模：10+兆字节（MB）。
数据文件形式：单个文件或数据库即可囊括全部采集数据。
