Long-term Limnological and Aquatic Resource Monitoring for Lakes Mead and Mohave
Several fish species inhabit Lakes Mead and Mohave, including game, non-game, and federally listed species that depend on clean water and high quality habitat to maintain healthy populations. Lake Mead provides a nationally recognized sport fishery with an average of 205,1641 angler use days annually, making it the most popular destination for fishing in Nevada. Lake Mohave is also a popular sport-fishing destination that supports, on average, 45,1061 angler use days annually. Predominant introduced sport fish within these lakes include largemouth bass, striped bass, blue gill, and channel catfish, among others. The fishery is dependent primarily upon threadfin shad (forage fish) production as a food source. Lakes Mead and Mohave also provide habitat for populations of razorback sucker, a federally endangered fish endemic to the Colorado River system. Lake Mohave houses the Willow Beach National Fish Hatchery, which produces thousands of rainbow trout and raises imperiled fishes such as razorback sucker and bonytail chub for reintroduction efforts. Fish require high water quality and available food resources to maintain healthy populations. Monitoring and research are necessary to track populations and determine health status. Management of both lakes to meet recreational, wastewater, drinking water, hydropower, and flood management needs must be balanced to ensure the integrity of fish populations and their habitats are sustained.
