• Aban Creek • Salazar Creek • Carnero Creek • San Francisco Creek • Torcido Creek • Jaroso Creek • Quates Creek • Several other small tributaries to Culebra Creek • Costilla Creek (Colorado portion) Culebra Creek extends from its headwaters in the Sangre de Cristo Range in the southern part of the San Luis Valley to its confluence with the Rio Grande. Although the historic Creek channel extends to the Rio Grande, water does not flow to the River as it is entirely diverted upstream. Costilla Creek is also within District 24, and its water use in Colorado is limited to conditions set forth in the Costilla Creek Compact (discussed further below). Stream Flow Measurement Points There are several stream flow measurement points along the Culebra Creek and tributaries within District 24. The most significant measurement point the USGS gauging station located at Culebra Creek at San Luis (ID No. 8250000). Gages are also located on Culebra Creek near Old San Acacio, and on Ventero Creek above and below Sanchez Reservoir. There is also a gage on Costilla Creek at the New Mexico state-line (ID No. 8261000) and several gaging stations located on canals that divert water from Costilla Creek in New Mexico (Acequia Madre, Acequiacita, Chalifu, Trujillo, Garcia, and Cerro ditches, and Eastdale Reservoir). Direct Flow Water Rights and Ditch Capacity Issues There are approximately 60 decreed surface water diversion points within District 24. Included are several small diversions at points located on tributary streams. A straight-line diagram for the District is provided as Attachment 1. In addition to structures that divert water from Culebra Creek and its tributaries, there are seven structures that receive water diverted from Costilla Creek in New Mexico. Included are: • Acequia Madre • Acequiacita • Chalifu Ditch • Trujillo Ditch • Garcia Ditch • Cerro Ditch • Eastdale Reservoir The straightline diagram in Attachment 1 does not indicate the Costilla Creek ditches, as water deliveries to these structures are administered under the Costilla Creek Compact. Water deliveries to the state-line are administered by a interstate "water master" that is responsible for equitable division of Costilla Creek waters in New Mexico and Colorado. All diversion structures on Culebra Creek and its tributaries are equipped with measuring devices. The majority of measurement devices consist of Parshall flumes of various sizes.
