| Chances of ZEBRA MUSSELS colonization in Jackson
Gulch Reservoir are very low.
Coal outcrops contribute CO2 to the lake, and CO2 concentrations are fatal
Given the adaptive nature of the quagga mussels, the growth and expansion
of Dreissena needs to be monitored for many years before any lake or water
body can be declared invulnerable to colonization. Environmental conditions that
they can tolerate should be studied further.
The potential is low for establishment of Dreissena at Jackson Gulch
Reservoir. The geology of the reservoir basin includes coal seams in the Dakota
Formation. Coal contributes dissolved CO2 to the water, and high CO2
concentrations are fatal for Dreissena and interfere with development of their
Compared with lakes across the U.S. with zebra and quagga mussels,
Jackson Gulch has much different water quality with lower CalSat Potential, low
pH values, and high CO2 concentrations. The conditions are Jackson
Gulch, therefore, are unsuitable for zebra and quagga mussel colonization.
However, given the ability of these mussels to adapt to their environment,
the growth and expansion of Dreissena needs to be monitored, and water-quality
conditions where they survive must be documented. More research needs to be
done on the potential for Dreissena to be transported downstream from lakes to
rivers and canals.
