Hydrologic investigations to improve runoff and streamflow forecasting procedures and flood frequency evaluations were continued from prior years. Studies were made of flood flows versus causes and of flood frequency statistics versus basin physical and hydrologic environment factors. Fiscal year cost of those studies was $5,500.
