Prepared for United States Fish and Wildlife Service; United States Army Corps of Engineers; United States Environmental Protection Agency, Region 6; New Mexico Environment Department; Albuquerque Metropolitan Arroyo Flood Control Authority; Middle Rio Grande Conservancy District
Dear United States Fish and Wildlife Service; United States Army Corps of Engineers; United States Environmental Protection Agency, Region 6; New Mexico Environment Department; Albuquerque Metropolitan Arroyo Flood Control Authority; Middle Rio Grande Conservancy District, I am a resident and member of the public requesting a prompt, documented investigation and coordinated response concerning the drainage or retention area near 6440 Coors Boulevard Northwest, directly east of Sagebrush Church–Riverside Campus, Albuquerque, New Mexico 87120. POTENTIAL LEGAL ISSUE AND REQUIRED CAVEAT Rio Grande silvery minnow and critical-habitat impacts — Endangered Species Act §7 Potential federal review issue: agencies should determine whether the site has a hydrologic or discharge relationship to the Middle Rio Grande and whether federal action could affect the endangered Rio Grande silvery minnow or its designated critical habitat. Law: 16 U.S.C. §1536; critical-habitat designation at 68 Fed. Reg. 8088 (Feb. 19, 2003). FULL LEGAL CITATION AND ELEMENTS TO REVIEW Review Endangered Species Act §7, 16 U.S.C. §1536, together with the Rio Grande silvery minnow critical-habitat designation at 68 Fed. Reg. 8088 (February 19, 2003). The agencies should determine whether the La Orilla drainage has a hydrologic, discharge, groundwater, sediment, or watershed connection to the Middle Rio Grande and whether any federal action may affect the species or its critical habitat.

Federal Register, 68 Fed. Reg. 8088 — complete rule notice https://www.federalregister.gov/documents/2003/02/19/03-3255/endangered-and-threatened-wildlife-and-plants-designation-of-critical-habitat-for-the-rio-grande ISSUE-SPECIFIC EVIDENCE STATUS CURRENT FACTUAL BASELINE (reviewed August 29, 2026) Albuquerque Metropolitan Arroyo Flood Control Authority identifies the site as the Albuquerque Metropolitan Arroyo Flood Control Authority-owned La Orilla Outlet Water Quality Structure. Albuquerque Metropolitan Arroyo Flood Control Authority authorized the on-site work at the La Orilla Outlet Water Quality Structure; that agency authorization does not by itself establish that every required permit or regulatory approval was satisfied. Albuquerque Metropolitan Arroyo Flood Control Authority reported that approximately 8–10 turtles, primarily red-eared sliders, and several bullfrogs had been captured or relocated as of August 26, 2026; wildlife professionals were involved, work was paused after wildlife concerns, relocation was not complete, and no dead or injured wildlife had been found at that point. The supplied photograph directly depicts one beaver, and witness material records direct observation of at least two beavers and one beaver den; Albuquerque Metropolitan Arroyo Flood Control Authority stated that it had not independently confirmed the beaver observation as of its August 26, 2026 public statement. A supplied photograph depicts an animal appearing to be a deceased beaver beside a roadway. In a public Facebook post, Brittany Walters says Jenn Wilson photographed the animal near Paseo and Coors and identifies it as the same beaver the community had been trying to save based on matching tail notches; the identity and the cause, timing, and circumstances of death have not been independently verified. Supplied text-message screenshots report more than 40 turtles identified in the account as snapping, western painted, red-eared slider, and spiny softshell turtles, plus one unidentified snake, many bullfrogs, and a possible alligator; the counts and species identifications require qualified official verification. Historical federal scientific records document Rio Grande silvery minnows at a La Orilla Middle Rio Grande study location; that historical evidence does not establish that silvery minnows were present inside the specific Albuquerque Metropolitan Arroyo Flood Control Authority La Orilla Outlet Water Quality Structure during the August 2026 operation. Albuquerque Metropolitan Arroyo Flood Control Authority stated that water was pumped downstream along the structure’s normal drainage path toward the Rio Grande and that water-quality samples were collected; laboratory results were pending at the time of its August 26, 2026 statement. Albuquerque Metropolitan Arroyo Flood Control Authority stated that permanent drainage modifications were under consideration. The reviewed public record does not establish the full permit history, precise regulatory jurisdiction, specific discharge authorization, detailed laboratory results, all relocation destinations, complete injury or mortality records, or final permanent-design effects. Images of fresh soil, equipment activity, and wildlife at the drainage area, together with news reporting, document the concern, but the public record does not establish a federal permit, funding source, land interest, civil-works project, retained federal control, action agency, listed-species action area, historic property, or completed federal review. Those threshold facts must be identified before the cited federal process can be found applicable or deficient. Historical federal scientific records document Rio Grande silvery minnows at a La Orilla Middle Rio Grande study location; that historical evidence does not establish that silvery minnows were present inside the specific Albuquerque Metropolitan Arroyo Flood Control Authority La Orilla Outlet Water Quality Structure during the August 2026 operation. ISSUE-SPECIFIC RECORDS AND FACTUAL QUESTIONS Map the drainage and receiving waters; test for downstream transport of sediment, pollutants, or altered flows; identify federal permits and funding; determine whether designated habitat is within the action area; and obtain the species-effects and consultation record. WHY PROMPT ACTION IS WARRANTED Further filling, pumping, dewatering, grading, vegetation removal, cleanup, or animal handling could alter site conditions, make water-quality or wildlife effects harder to detect, destroy evidence, and foreclose less damaging corrective options. The available record warrants inspection and preservation now even though jurisdiction, permit status, causation, species, injury, and the elements of any violation remain to be established. COORDINATED REQUEST BY RECIPIENT ROLE United States Fish and Wildlife Service — Primary enforcement or regulator Request immediate coordination among the action agency, the Service, water-quality authorities, and watershed managers; protect hydrologic connectivity; and complete Endangered Species Act review before irreversible filling, draining, or discharge continues.
