Streamflow data, including average seasonal flow, average annual flow and other information is shown in Table 3.12-2.  The basin does not contain flood ALERT equipment.  Reservoir and stockpond data, including maximum storage or maximum surface area of large reservoirs and type of use of the stored water, are shown in Table 3.12-3.   The location of streamflow gages identified by USGS number and large reservoirs are shown on Figure 3.7-4.  There were no runoff contours for this basin. Descriptions of stream, reservoir and stockpond data sources and methods are found in Volume 1, Appendix A. Additional information on surface water in this basin can be found in Section 3.12.5 - Perennial/Intermittent Streams and Springs and Section 3.0.2 - Surface Water Hydrology. Where available, the header for each section provides a link to the data web site.
