after this event, as well as minimum flows to provide for other uses before and after <br />the main season. The winter flows provide the minimum necessary flow to allow for <br />ongoing daily training by Durango's competitive programs. <br />The intention of these flow regimes is to provide for the City's intended purposes at the <br />specific structures. The regimes were structured such that from January until mid -March <br />minimum flow is available for winter freestyle, slalom and recreational paddling. At these <br />flows there will be sufficient depth in the main channel and definition in the features and <br />eddies to allow for fitness training, skill development, and low end recreational boating. <br />Given the dimensions of the river, the hydraulic that will be formed at this level, though <br />surfable in most instances, will not prove to be an attraction to out -of -town freestyle <br />boaters. This flow will provide for Durango's active training program as well as boaters who <br />choose to paddle recreationally year round. <br />Mid -March flows increase with the hydrograph in order to allow for increased power in the <br />river. This increased power allows practicing and training boaters to begin to prepare for the <br />higher flows of spring. <br />As river flows begin to increase in April, the minimum flows at the boating park structures <br />also increase. For the aforementioned training athletes these flows allow paddlers to begin <br />to tune their efforts towards the competitive season, and for recreational boaters these flows <br />provide added attraction and begin to prepare these boaters for the higher flows that are still <br />to come. Lastly, these flows, in comparison to alternative local and regional alternatives, <br />maintain Durango's reputation as an attraction. This is to say, in comparison to alternative <br />destinations, the Animas at the boating park will be a superior attraction. These flows will <br />be a marked increase from the off - season flow in terms of flow rate, power, and definition, <br />but will be largely limited to a single channel and single current profile. Features will allow <br />for play - boating and surfing at the drop structures in the hydraulic jump that will be formed <br />there. This hydraulic jump will be surfable in early April but will not have the size and <br />power that will be seen at later flows. Late April flow will be sufficient to provide a <br />hydraulic of sufficient size and power to begin to attempt more powerful and dynamic <br />
