21_-_2018__Dam_Safety_Inspection_Letter_for_Crystal_Springs.pdf

This is a dam safety inspection letter dated November 1, 2018, from the Nevada Department of Conservation and Natural Resources Division of Water Resources regarding the Crystal Springs Dam (J-123, NV00189) at Ash Meadows National Wildlife Refuge. The inspection, conducted on October 3, 2018, classified the dam as a Low hazard structure with an overall FAIR condition rating.

The letter outlines three required long-term (2-year) corrective actions: 1) placement of erosion protection on the embankment face where gullies exist, 2) implementation of a rodent control program with backfilling and compaction of any discovered holes, and 3) removal of vegetation within 25 feet of the structure. Photos documenting the erosion gullies and vegetation issues are included. The letter emphasizes that while these are maintenance issues not requiring new permits, future modifications may require plan submittal and approval. The dam owner is reminded of their responsibilities under Nevada law (NRS § 535.030) for safe operation, maintenance, and compliance with state regulations.
