<br />3 <br /> <br />Comments on Naturally Flooding Wetlands Should be Used to Develop <br />Management Criteria (page 3). <br /> <br />I am somewhat confused by this paragraph. It needs to be more <br />clearly stated. If I understand the process, you intend to use some form of <br />monitoring to quantify fish population response to "manipulated sites", <br />"restored sites where levees have been removed", and '''existing reaches of <br />the floodplain that presently flood during recurring flood pulse events under <br />today's dam management scenario". I like this idea and believe that you do <br />not need a massive sampling protocol to compare the three concepts but <br />rather you should devise an index of relative success (e.g., standard wing- <br />net survey of the shoreline in each area at the same time during the annual <br />flood pulse period). <br /> <br />Comments on Nonnative versus Native Fish Enhancement (page 4). <br /> <br />If you design an intensive sampling effort for a short time period for <br />each type of area (preferably in a replicated experiment), it should be <br />possible to index both native and nonnative usage of the three types of sites <br />with one standard survey. Most of the nonnative fish you described will be <br />readily captured with wing or trap nets especially if both small and medium <br />mesh nets are used. <br /> <br />Comments on Goals, Objectives and Hypotheses (page 5). <br /> <br />The goal statement should include levee removai. For example; "To <br />restore and enhance natural floodplain habitats and functions that support <br />recovery of endangered fishes in the upper Colorado River basin through <br />selective removal of levees. <br /> <br />Since this is a.strategic plan for levee removal, 1 am confused why <br />there are objectives included for floodplain wetland restoration? I would <br />delete the heading, i.e. FLOODPLAIN WETLAND RESTORATION <br />OBJECTIVES. Then include 1. Reconnect flood plains with channel, with <br />the objectives under LEVEE REMOVAL OBJECTIVES. Delete 2. Evaluate <br />system responses. 3. Use manipulated......questions. and 4. Implement <br />adaptive management under FLOODPLAIN WETLAND.......OBJECTIVES. <br /> <br />Objectives 1 and 2 under LEVEE REMOVAL OBJECTIVES seem to be <br />redundant, I would replace Number 1 with Number 1 from the WETLAND <br />section. Objective 3; I recommend that the benchmark for timing and <br />duration of inundation should be the historical condition (e.g., percentage of <br />mean daily flow from a precontrol periOd) not the result of artificial flooding <br />in sites such as Old Charlie Wash. <br />
