Hydrologic Data For Experimental Agricultural Watersheds In The United States

This publication presents selected hydrologic data for the calendar year 1968 and earlier years for some watersheds. It includes data include monthly precipitation and runoff, annual maximum discharges and annual maximum discharge and volume of runoff for 204 intervals of 1, 2, 6, and 12 hours and for 1, 2, and 8 days for 174 watersheds; daily precipitation for 157 watersheds; daily maximum and minimum air temperatures for 16 watersheds; and detailed information for 1 or more selected typical storm events for 116 watersheds.

This publication presents basic data on monthly precipitation and runoff; annual maximum discharges and volumes of runoff; and selected runoff events with associated data on rainfall, land use, and antecedent conditions for agricultural watersheds where research studies were in progress in the period 1956-59. Its presentation is a continuation of the activity of processing and releasing hydrologic data of general interest gathered cooperatively with other agencies.

This publication presents selected hydrologic data for 171 watersheds for the calendar year 1964. The data include monthly precipitation and runoff for 163 watersheds; annual maximum discharges and the watersheds for time intervals of 1, 2, 6, and 12 hours and for 1, 2, and 8 days; daily precipitation and discharge or daily air temperature on 58 watersheds, or both.
