Relation Central Utah Project; Western Waters Digital Library; remains high for several months while the root systems penetrate into deeper water sources the success and extent of these marsh communities will largely depend upon frequency and duration of flooding by goshen bay brackish waters Mos mosquito guito gueto problems and control the greatest contributing factor to mosquito production in the proposed project features associated with the goshen bay dike is the frequent reflooding flooding re of lands behind the dike the average north south gradient of lake botton in goshen bay behind the dike is approximately 0.00012 000012 or 012 .012 012 percent this means that an increase in water depth of one foot will cover a zone 8800 feet wide across the bay assuming a five mile length to this zone that would result in flooding of over 5000 acres of mosquito breeding habitat with water from 0 12 inches deep the acceptable range for most mosquito species in simulations some years are projected as having as much as an eight foot vertical fluctuation in water depth in goshen bay most years the value is closer to two feet 10000 plus acres of flooded habitat the utah county mosquito abatement district estimates that it would cost approximately 90000 per year of 1981 dollars to contract the additional mosquitoes in goshen bay following diking if the majority of the area frequently flooded and dried becomes vegetated with saltcedar salt cedar control of mosquitoes will become extremely difficult the highest production of mosquitoes is often in salt sait saltcedarsaltgrass cedar sait salt saitgras gras s vegetated areas table 2d ad 2 but the dense cover prevents good penetration of larvicides applied from the air thus percent of kill is often low the dense saltcedar salt cedar vegetation does not allow ground application of larvicides deer and horse flies deer and horse flies called tabanids taban ids have aquatic to semi aquatic larvae they are found as larvae in the mud of areas c completely flooded at least during the spring and early summer and in exposed but wet soil 3 95
