Notes |
Records fair except those for estimated daily discharges, which are poor. Flow primarily regulated by control structure S-355 upstream and G-211 downstream; occasionally S-334, S-336, G-119 upstream and S-338 downstream also affect L-31 canal flows. The control structure S-24 located near the Tamiami Trail bridge is not used for regulation. The manual operation gated culvert S-24A, that is located 2 mi upstream is inoperable. Positive flow is to the south and may reverse for short periods. Discharge computed from relations between stage vs. area and index velocity vs. mean channel velocity. |
