Estimates of 7-day, 10-year minimum flows at selected stream sites in Puerto Rico

The 7-day, 10-year minimum flow of streams is used as an index for determining the capacity of streams to receive waste effluents. This index of flow was computed from streamflow records for 31 stream sites in Puerto Rico. In addition, there was a need for the 7-day, 10-year minimum flow at an additional 15 stream sites for which adequate streamflow data were not available. The flow index was estimated at these sites on the basis of available record, records at nearby sites, and comparisons with drainage areas.
