The Economic Impacts of Trout Stocking on State Tailwaters In The Economic Impacts of Trout Stocking on Tailwaters in the Southeast Aquatic Resources Partnership (SARP) November 6, 2007 Prepared by: James Caudill, Ph.D. Division of Economics U.S. Fish and Wildlife Service Arlington VA The Economic Impacts of Trout Stocking on Tailwaters in the Southeast Aquatic Resources Partnership (SARP)1 Introduction This report summarizes the economic impacts associated with recreational angling for trout stocked in tailwaters in the Southeast Aquatic Resources Partnership (SARP). There are 11 member states in this report, including Alabama, Arkansas, Georgia, Kentucky, Missouri, North Carolina, South Carolina, Oklahoma, Tennessee, Texas and Virginia. Table 1 shows the 54 dams in these states included in this report. The main sections of the report include: (1) a brief discussion of the purposes and objectives of the Southeast Aquatic Resources Partnership; (2) a summary of the current stocking program at each of the dams; (3) a discussion of the economic effects attributable to the recreational angling of rainbow trout produced; (4) an estimate of recreational angling days, (5) an estimate of the retail expenditures associated with recreational angling on dam tailwaters; (6) the economic impacts associated with these expenditures; (7) an estimate of the economic value of the recreational angling on these tailwaters; and (8) a comparison of economic impacts and value with stocking costs. SARP Background and Objectives The Southeast Aquatic Resources Partnership (SARP) was initiated in 2001 to address the myriad issues related to the management of aquatic resources in the southeastern United States. These issues include significant threats to the aquatic resources of the Southeast, as illustrated by the fact that 34% of North American fish species and 90% of the native mussel species designated as endangered, threatened, or of special concern are found in the Southeast. Given these stark realities, and the predicted increased pressure on Southeast aquatic resources in the future, SARP was established with the following mission: With partners, protect, conserve, and restore aquatic resources including habitats throughout the Southeast, for the continuing benefit, use, and enjoyment of the American people. This partnership envisions a southeastern United States with healthy and diverse aquatic ecosystems that support sustainable public use. The SARP was formed under the realization that the individual members lack sufficient resources to effectively meet the aquatic resource management and conservation challenges throughout the Southeast on a landscape basis and must therefore work cooperatively to design a process that will attain the desired common goals. The intent of the SARP is to develop State and Federal partnerships that will extend beyond the traditional boundaries of fishery resource management agencies and will establish a commitment to truly work together for the benefit of the resource. It will shift the focus beyond what are individual Federal and State responsibilities to what are joint responsibilities to the resource. Long term success of this partnership will require a move to a higher level of coordination built upon mutual trust that will focus on making things happen at the ground level. The SARP is comprised of representatives from: 1 Significant help and assistance from Frank Fiss, Trout and Stream Fisheries Coordinator for the Tennessee Wildlife Resources Agency is gratefully acknowledged. Any and all errors of fact or interpretation are the sole responsibility of the author. The views and conclusions in this report do not necessarily represent those of the U.S. Department of the Interior or the Fish and Wildlife Service. 2 14 southeastern states (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia; inland and marine divisions in most coastal states). The U.S. Fish and Wildlife Service (FWS), National Marine Fisheries Service (NMFS), Gulf States Marine Fisheries Commission (GSMFC), and the Gulf and South Atlantic Fishery Management councils (GMFMC and SAFMC). All Southeastern Association of Fish and Wildlife Agencies (SEAFWA) states are invited to participate. Non-governmental organizations (NGOs), grassroots groups, industry, business, and private sector interests are also invited to participate. SARP focuses on six key issue areas of greatest concern and interest to the Southeast: 1. Public Use 2. Fishery Mitigation 3. Imperiled Fish and Aquatic Species Recovery 4. Inter-jurisdictional Fisheries 5. Aquatic Habitat Conservation 6. Aquatic Nuisance Species (ANS) This report focuses on one particular issue, the economic effects of trout stocking associated with fisheries mitigation. SARP Stocking by State Table 1 shows the dams by state which are considered in this report. Of the 54 dams, Alabama has one dam, Arkansas has eight, Georgia has two, Kentucky has fourteen, Missouri has one, North Carolina has five, Oklahoma has two, South Carolina has two, Tennessee has thirteen, Texas has one and Virginia has five. These dams are associated with 56,776 square miles of watershed and 592 river management miles. The Army Corps of Engineers manages 28 of the dams, the Tennessee Valley Authority operates 12, and city, state or regional power companies manage the remaining 14 dams. Table 2 shows annual tailwater stocking below each dam for recent years by state (some tailwaters may not be currently stocked). Both catchables (6-8 and 9-11 inch trout) and fingerlings are shown. Stocked catchable trout average about 4.1 million annually and fingerlings average 1 million annually, totaling 5.1 stocked trout on average each year. Table 3 shows annual stocking by state. Arkansas stocks about 1.9 million trout annually (38 percent of total), Tennessee 1.3 million (26 percent), and Missouri 760,000 (15 percent). The remaining eight states account for 21 percent of total stocking. Of the total stocking, 9 - 11 inch trout account for 77 percent of annual stocking, 6-8 inch trout account for 3 percent and fingerlings account for 20 percent. 3 Table 1.

ABSTRACT Most of the dams built by the Bureau of Reclamation were completed before environmental regulations such as the Clean Water Act, National Environmental Protection Act, or Toxic Substances Control Act existed. The management and operation of dams was instituted under conditions where the ecology of the downstream habitat was unknown and largely ignored. Changing or modifying structures, flow regimes, and land use patterns are some of the efforts being pursued by the Bureau to reconcile or mitigate the effects of impoundment to comply with these environmental policies and to maximize the potential for recreation, fisheries, and water quality in tailwater habitats for the water resource users. The purpose of this report is to provide a reference document intended to aid in the management, compliance, and problem solving processes necessary to accomplish these goals in Bureau tailwater habitats.

  • Utilization of Unique Tailwater Habitats Below High-Head Dams Has Become
    Brown Trout Population Response to Trophy Regulations and Reservoir Discharge in a Large, Southeastern U.S. Tailwater by: David P. Dreves, Jeff R. Ross, and Jarrad T. Kosa Bulletin No. 111 March 2014 BROWN TROUT POPULATION RESPONSE TO TROPHY REGULATIONS AND RESERVOIR DISCHARGE IN A LARGE, SOUTHEASTERN U.S. TAILWATER By David P. Dreves, Jeff R. Ross, Jarrad T. Kosa Kentucky Department of Fish & Wildlife Resources March 2014 Partially funded by Sport Fish Restoration Funds Sport Fish Restoration Project F-40 “Statewide Fisheries Research” ABSTRACT Reservoir tailwaters can be an important resource for developing quality trout fisheries, especially when managed with special regulations. The objective of this study was to evaluate the effectiveness of a 508 mm minimum length limit and a one-fish-per-day creel limit on improving the size structure of the brown trout Salmo trutta population in the Cumberland River below Lake Cumberland, Kentucky. The purpose of the new regulations, which did not include gear or bait restrictions, was to increase the numbers of quality (381-507 mm total length) and trophy-size (≥ 508 mm total length) brown trout in the 121 km tailwater. A significant increase in brown trout electrofishing catch per unit effort was observed across years for small (< 381 mm), quality, trophy-size trout, and all sizes combined. As brown trout electrofishing and angler catch rates increased over time, no corresponding decrease in growth or condition was observed. Reservoir discharge was positively correlated with warmer water temperatures and lower dissolved oxygen in the tailwater. Growth and condition of brown trout in the tailwater were inversely correlated with an index of discharge from the reservoir.

First, my co-authors and I have conducted a review of positive interactions in freshwaters to establish a direction for future research. By outlining case studies and causal mechanisms, we illustrate the diversity of positive interactions, and set the stage for a comprehensive look at the role of context in shaping interaction outcomes. Our research directive focuses on the value of both basic life history and experimental research, then using those findings to investigate these interactions under different contexts, in different levels of ecosystem structure, and at multiple geographic scales.

  • Tailwater Recovery and On-Farm Storage Reservoir: System Overview
    Tailwater Recovery and On-Farm Storage Reservoir: System Overview Tailwater recovery (TWR) systems are a combination of financially assisted (by Natural Resources Conservation Service) conservation practices aimed at collecting runoff and storing that water for irrigation. As freshwater resources for irrigation decline, this surface water storage structure is a viable option for capturing and recycling precipitation and irrigation runoff. Figure 1. Top: Section view diagram of a TWR system installed in Mississippi’s Delta region. Middle: Plan view diagram of the same TWR system. Bottom: The TWR system shown in diagrams. Potential practices in TWR systems • Critical area stabilization (342) • Pumping plant water control (533) (NRCS practice codes): • Irrigation water conveyance (430) • Access road (560) • Irrigation reservoir (436) • Irrigation water management (449) • Water control structures (587) • Tailwater recovery (437) • Precision land forming (462) • Dikes (356) In-Field TWR System Practices Precision land form- ing (land leveling, land grading) is used to direct water to one end of the field by grading the field with a slope of 0–0.1 inch per 100 feet run for rice and 0.1–0.2 inch per 100 feet run for cotton, corn, and soybeans.
