<br />Basalt, Pitkin County, Aspen and Redstone, the various communities in the Rio Grande Valley <br />and other communities all implemented "advance measures". Those "advance measures" included <br />prepositioning sandbags, mobilizing contractors for emergency work, reallocating funds for <br />floodfighting, setting up floodcasting stations and implement mitigation plans. <br /> <br />Knowing the "channel capacities" was a very important piece of information in flood <br />management and preparedness. By knowing the existing channel capacities and receiving a <br />reasonably accurate floodcast, it was possible for the local government officials and property <br />owners to determine what level of emergency flood protection was adequate. They could identify <br />potential breakout points, critical bridges and culverts and buildings in need of special protection. <br />The Division of water resources stream gaging network played a very important role in the <br />monitoring of spring snowmelt flooding. <br /> <br />Reservoir Ooerations <br /> <br />Chatfreld, Bear Creek, Reudi and the Colorado Storage Project <br /> <br />During the 1995 snowmelt runoff and spring flood, the flood control and "non-flood <br />control" reservoirs played a role in the detention of floodwaters and the reduction of flood flows. <br />This was evident is in the Gunnison and South Platte River basins. However, we learned that <br />there is a need to better coordinate the operations and releases of the reservoir pools during the <br />spring runoff season. The Board and Office of Emergency Management staffs are in <br />communication with the Corps of Engineers, Bureau of Reclamation, Denver Water Board, and <br />private reservoir companies regarding future operations. <br /> <br />Like reservoir operations aild releases, irrigation company diversions, operations and "by- <br />passes" can have a major effect on downstream flood flows and inundation of floodplain lands <br />and property. On the Roaring Fork, Rio Grande, Cache La Poudre, North Fork of the South <br />Platte, Lower South Platte and Upper, Blue, Colorado, and Lower Arkansas Rivers, the irrigation <br />diversions assisted in the reduction of flood flows. State agencies have no jurisdiction over these <br />private irrigation companies as to their flood protection responsibilities during flood. These flood <br />protection benefits must be viewed as incidental, This flood protection can only be obtained <br />through friendly negotiations and mutual agreements for securing flood control benefits, Local <br />governments cannot take such flood protection for granted annually without implementing better <br />management practices. <br />
