Figure 8. Water elevation changes at Ives Island and depths at free embryo and larvae capture sites. Horizontal dashed lines indicate minimum water surface elevations needed to maintain water over capture sites. All sites were dewatered for short periods after free embryos or larvae were captured. Site 47 was dewatered less than 24 hours after one larva was captured there.
