| Relation | Central Utah Project; Western Waters Digital Library; comment letter no 25 there is mention of providing floods every two years does not a river flood every year and in the case of the provo river this flooding occurs in june floods in rivers start in the headwaters and is a continual process throughout the river drainage floods do not start from dams and reservoirs floods change the river courses this project is designed with stream bank stabilization large artificial rocks places in the outward 25.2 252 bend of the created meanders floods always contain waters with sediment and yet sediment erosion is to be controlled uNa natural unatural unnatural tural turai tunal cottonwood recuitment recruitment depends on the dynamics of flood flows that cause surface scour and sediment deposition page P 318 how will this occur when the stream banks are stabilized can you really call a flood a movement of water 0.1 01 oi ol to 0.5 05 05 feet deep that is released from a dam and reservoir flood plains contain many kinds of aquatic habitats old ox bows sometimes obtain new water from surface floods most often they receive new waters by hyporheic hypo rheic flows a form of ground water associated with rivers and has a unique largely blind and albino biotic community in its own right these habitats would be largely fishless and very promising for amphibians and amphibious fauna only fish lakes and ponds 15 feet deep are proposed in the PRRP and these ponds will have a continuous flow of 25.3 253 water input and fish from synthetic channels the entire flood plain in PRPP is designed for fish production will there be any attempt to create or preferrably have formed naturally temporary ponds of duration for 2 weeks to 10 months with no channels to the fish inhabiting waters these would be your typical mosquito ponds but the longer lasting ponds have greater biological diversity schneider and frost 1996 habitat duration and community structure in temporary ponds J N am benthol soc 15 15164186 15164 164186 164 186 there is comparison of PRRP with two other projects that have occurred P 335 3 35 this 1 assessment isfully is fully appreciated it would be of interest to me to know if the east fork 25.4 254 of the sevier and the bear valley creek have dams and reservoirs above their improved river reaches and even below their river reaches one can greatly improve the rivers by staying within the natural confines of the river it takes very little effort to improve rivers if the rivers are not heavily impacted there is the question of other aquatic resources I 1 have spent considerable time now in examining the collections of mollusks and leeches and amphibians in the nations museum collections this project will continue for another 5 years in part this project evolved out of a need to determine what the great basin and colorado river basin historically contained and in part out of a need to understand the geography of the aquatic fauna within these basins parallel efforts have been to inventory the aquatic fauna mollusks leeches and amphibians in the great basin there is a large disparaty disparity dispa raty between what was found 50 years and 100 years ago and what is found now the amphibians leopard frog woodhouse toad and boreal toad have been largely exterminated from heber valley probably do to loss of breeding habitat no fishless ponds of several feet deep the mussel margantifera margaritifera Marganti Margarit fena fera ifera falcata may no longer occur in the provo river although shells are still occasionally found as a reminder of past page im 2 of 5 4216 4 216 |
