Some potential exists to switch management strategies away from Intensive Use (put/take <br />catchable trout) to Optimum Use (put-grow-take). In all waters, such a management strategy <br />would probably have to incorporate reduced bag and size limits with terminal tackle restrictions. <br />If this alternative is chosen, implementing it over time with a significant public education effort to <br />gain understanding and acceptance of this alternative would be best. The switch of management <br />strategies away from put/take to put-grow-take in standing waters may not require changes in <br />regulations, particularly on the west slope, where angling pressure is much lower. <br />Enhance and Protect Coldwater Habitat <br />Protection and improvement of Colorado's aquatic resources have been a high priority for <br />some time. Water quality research and investigations in support of appropriate stream standards, <br />DOW involvement with nonpoint discharge projects, public education and water testing through <br />the Riverwatch Program, water quality control at our production units, instream appropriations <br />through the CWCB, forest and land use plan review, EIS preparation, and review and habitat <br />manipulations on state and federal lands, all contribute to ensuring high water quality. <br />Nonetheless, with increasing pressures placed on our aquatic environments, there is a need to <br />increase and broaden our efforts. <br />Part of the debate in Colorado over the use of angler dollars involves what we are not doing <br />with the funds spent on fish production. The concern typically addresses the question as to the <br />appropriate allocation of funds between various DOW activities. Frequently, funding levels for <br />fish production and habitat protection/enhancement are compared. <br />Many aquatic habitat issues are not under the jurisdiction of the DOW, but with other <br />federal (USFS, BLM, EPA, Corps of Engineers) or state (Colo. Water Conservancy Board, <br />Department of Health) agencies. Nonetheless, the DOW is an active participant to the extent that <br />we are authorized to do so. DOW's lack of staffing for field investigations, data analysis, <br />negotiations, and review is likely limiting our (and other agencies') abilities to solve aquatic <br />habitat problems. <br />Becoming more aggressive in aquatic habitat protection and enhancement would require the <br />reprioritization of permanent FTE, some of which is currently occurring, as well as capital <br />expenditures for actual enhancement projects. Given the limited time and scope of this report, <br />any quantification of benefits (increased biomass of wild trout, recreation days) was impossible. <br />Acquire New Coldwater Access <br />A preliminary assessment of this option involved asking DOW senior fishery biologists for <br />their appraisal of potential new areas for acquisition. Although predicting options for new <br />acquisition or leases always involves guesswork, the prospects for significant new access are not <br />considered promising. Much of the high-quality stream access has already been acquired by the <br />DOW, with most recent purchases/leases coming in at considerable cost. An example was the <br />28
