BENTHIC MACRO-INVERTEBRATE
SURVEYS (BMI): Staff completed the
annual BMI survey in early November at five sites, between
REMOVAL OF FISH MIGRATION OBSTRUCTION: This past fall, during routine river-flow monitoring above Los Padres Reservoir, District staff discovered that a large rock slide had blocked nearly the entire river in a steep canyon approximately one mile above the reservoir. Staff was concerned that the slide could block both migrating steelhead adults and smolts. In early December 2007, District staff and California Department of Fish and Game personnel were able to create a small bypass channel around the edge of the slide by jack hammering out a few large boulders and filling in gaps between other rocks. Staff will continue to monitor the site.
SLEEPY HOLLOW STEELHEAD REARING FACILITY: The first rescued fish were brought to the Facility on May 14, 2007. As of December 31, 2007, a total of 10,846 fish has been stocked in thirteen tanks and troughs at the Facility. Most of the rescued young-of-the-year (YOY) fish started out quite small and represented a unique rearing challenge at the Facility. In addition, this year’s critically-dry inflow conditions increased the stress level in fish rescued from drying reaches and isolated pools, and many fish were infected with one of several diseases or parasites when they arrived at the Facility. With colder water temperatures dropping to as low as 43° F, disease outbreaks were negligible and mortality rates remained low in the last two months. Altogether, as of December 31, 2007, 2,976 fish (i.e., 2,829 YOY and 147 age 1+ juveniles) have survived, for an overall survival rate to date at the Facility of 27%.
