Merkys

The Merkys originates in the Oshmiany Upland (Aŝmena Upland). It is meandering in its upper and lower courses; it is fed primarily by groundwaters. There is high water from March through May. At 14 km from its mouth, the mean flow rate is 35.2 cu m per sec; the maximum flow rate is 498 cu m per sec. There is ice on the river from December through March, but the river does not freeze over for long (up to 1.5 months). The Merkys is used for floating timber.

Arvydas Povilaitis (2008) states that absolute values of deviation between the observed and estimated loads constitutes less than 10% from line of equivalence when testing MESAW model for the Merkys river (subcatchment #1).
For example, for the Merkys river subcatchment #1 Povilaitis (2008) reported that 60% of the total TN load is retained before the outlet, while the FyrisNP model simulates 26% retention for the same subcatchment.
