Riesel: A Local Treasure
By Daren Harmel
Did you know that there’s a world-famous outdoor research facility right here in central
Engineer and site manager Daren Harmel
The USDA-ARS Riesel Watersheds have provided valuable information to the water resource community for more than 70 years, making it one of the longest continuously monitored hydrologic research sites in the country. Long-term data sets are very rare, thus the 70 year data record from Riesel is extremely valuable for management of water supply, water quality, and flood impacts and for optimal design of culverts, bridges, detention basins and reservoirs. The information produced at Riesel is continually used by university, federal and state agency, and private consulting firms in hydraulic design, flood analysis, and infrastructure planning.
Currently, 13 water monitoring stations and 15 rain gauges are in operation to measure rainfall, runoff, and water quality on native prairie, improved pasture, and cultivated cropland. In addition to the active “edge-of-field” runoff sites, several larger stations located on Brushy Creek were monitored in the past.

Streamflow measurements at a Brushy Creek sampling station in the late 1930’s. This station was located on private land downstream of the federally-owned smaller watersheds.
Baylor University Geology Department professor Peter Allen says his department uses the Riesel Watersheds for senior and graduate classes in hydrology “because Riesel is an excellent example of a world-class hydrologic field lab with examples of instrumentation from weather stations to weirs.”
The Riesel Watersheds facility is an excellent site for visitors to learn about state-of-the-art hydrologic and water quality instrumentation. That’s because very few sites have the type and amount of instrumentation we have to measure rainfall, runoff, and water quality from small agricultural watersheds. Visitors also come to site the see the Texas State Soil, which is Houston Black Clay. This soil is infamous for its shrinking and swelling, which causes considerable soil movement and damage to building and road foundations.
Another valuable feature at the Riesel Watersheds is a remnant (native) prairie site, which provides a valuable baseline (natural background) view of water quality in the Texas Blackland Prairie.
The site is managed as a typical Central Texas farm and ranch operation and is designed to provide field-scale, real-world information, which is a real plus for Riesel. In a recently published paper on the history of Riesel Watersheds, I noted that in the mid-1930s USDA realized the importance of understanding hydrologic processes on agricultrual fields and watersheds and established three experimental watersheds. Of the three, the Riesel Watersheds and the North Applachian Expermiental Watershed near
Because water supply shortage, flood occurrence, and water quality degradation will increasingly affect the environment and future generations, watershed-based studies continue to be needed to solve these problems. With the Riesel Watersheds and ARS scientific expertise, we are here ready and willing to attack these new challenging questions and develop effective, economical solutions.
