At one location, East Branch Fishing Creek's
discharge is 19.7 cubic feet per second. The average discharges of the streams in the creek's watershed range from 63 gallons per minute at the headwaters of Heberly Run to 15,498 gallons per minute at East Branch Fishing Creek's mouth. The creek's watershed is
acidic. One contributing factor to this may be the presence of acidic
bogs. It is a
freestone stream. The average
pHs of the streams in the East Branch Fishing Creek watershed range from 4.32 to 5.76. The lowest pH occurs on Meeker Run and the highest pH occurs on Shanty Run. At two sites on East Branch Fishing Creek itself, the creek's pH is 5.34 (at its confluence with Lead Run) and 5.63 (at its mouth). The average amount of
aluminum in the streams in the watershed ranges from 0.024 milligrams per liter to 0.366 milligrams per liter. The highest concentration occurs on Ore Run and the lowest concentration occurs on the mouth of East Branch Fishing Creek. One stream in the watershed, Big Run, has a pH range of less than 3 to slightly under 7. The
main stem has a pH range of slightly over 4 to slightly over 6. During a study of the waters of East Branch Fishing Creek and its tributaries, no stream miles in the watershed have been rated as very good. 27% (9.23 stream miles) have been rated as good, 30% (10.21 stream miles) have been rated as fair, 14% (4.8 stream miles) have been rated as poor, 3% (1.07 stream miles) have been rated as very poor, and 26% (8.85 stream miles) have been rated as severe. The lowest-quality water tends to be on Meeker Run, Blackberry Run, Sullivan Branch, Ore Run, and Lead Run. Big Run, Quinn Run, and the East Branch Fishing Creek mouth have the highest-quality waters. East Branch Fishing Creek receives an average of 39.16
tons of
calcium carbonate per year. The number of pounds of acidity that flow through various streams in the watershed of East Branch Fishing Creek per day ranges from at the headwaters of Sullivan Branch to downstream of the confluence of East Branch Fishing Creek with Trout Run. The number of pounds of acid per day flowing through East Branch Fishing Creek itself ranges from downstream of East Branch Fishing Creek's confluence with Lead Run to downstream of East Branch Fishing Creek's confluence with Trout Run. The number of pounds of
aluminum that flow through various streams in the watershed of East Branch Fishing Creek per day ranges from at the headwaters of Heberly Run to downstream of East Branch Fishing Creek's confluence with Lead Run. The number of pounds of aluminum per day flowing through East Branch Fishing Creek itself ranges from at the creek's mouth to on East Branch Fishing Creek downstream of its confluence with Lead Run.

temperature on East Branch Fishing Creek in 2009 ranged from at various sites along the creek and its tributaries. == Geology ==
